Cheapest ways to increase power

-
You can do a lot with nitrous but the orignal poster siad he didn't want to use nitous. Also, headers, 4bl intake and 4bbl for a \6 is going to be close to a thousand bucks not to mention the $400 or so for a basic nitrous set up. That is close to the cost of a sb swap.

Building a \6 to make v8 levels of power is something you have to want to do, its not going to be cost effective compared to an engine swap. I will try and dig the photos out tonight and post them. I know a guy that built a multi-point fuel injected and turbo charged \6 for a 39 Willys pick-up he built for his shop truck. Even that engine doesn't have the power of a mildly warmed over sb but for a shop truck its perfect. This guy also has a blown hemi in a 41 Willys pick-up that he uses to scare women and make small children cry.

Can't argue with any of those points, but still, more people will be around the hood of a slant powered hot rod than any other at a car show...simply because they are something different.
 
The original poster's question:

What are the cheapest ways to increase power on a 225 slant six?

For a second there I thought the question was "How superior is a V8 to a slant six?"

Then I realized there's just a bunch of retards with poor comprehension skills responding to this thread.

I have also seen a guy who machined his stock /6 manifold to accept a 350 cfm Holley 2 barrel which has the same bolt pattern as the 500 cfm version
 
Actually they just make an adapter plate to put a Holley on the stock 2bbl manifold so there is no machining required.

With such a low post count, perhaps you missed the post regarding name calling. I refer you here:

There have been some good answers here with some great info for the OP. I think it would have been a bit more constructive to put your own two cents worth in about the OP's original question instead of trying to stir the pot by name calling. That was uncalled for. Besides that, there may well be someone here with a family member who has Down's syndrome. Did you ever think of that?
 
I hope no offense was taken by any actual handicapped people, I used it in the slang sense and figured it would be taken as so.

I just didn't realize that asking "How to get more power out a Slant Six" in the "Slant Six section" would lead to everyone simply telling him to rip it out and install a V8. Just seems... out of place, you know?

I'll put my guns away now, I don't hang out on the computer to try and make enemies. Peace?

Get used to it man. The V8 guys will never leave this section alone. I swear even if you ask "what kind of spark plugs should I use in my slant" they will say swap a v8 in there!

pick up a set of these motor mounts..letting you keep your stock K member, save a ton of work and money.
you're immediate parts list for a v8 swap

engine
torque converter
tranny (bellhousings are diff)
driveshaft (new or recut and welded)
8.75rear end if you plan on anything more than a mild 318
motor mounts
headers

now all of these parts you can spend whatever you want on, pending buddies, luck, spare parts.
example:. a torque converter can be had for $50..or 500...you get what you pay for..performance gains at the track are tremendious with a good 3000 converter (ATI, TCI)..but for street use, a decent 2500 B&M can compromise for 200)
remember stock and reused components only go so far with performance in mind (converter,gears,ignition components)

a stock slant six will run a 19.00 quarter mile with hwy gears( for the street racer above that outran some geo's.lol)
the best a (my) moderate 318 will do is 14.00, 3,91 gears.

paid 900 for a complete, running, 318 with an intake, cam, carb, headers, polish/port
paid 400 for a 727 tranny plus rebuild
200, completete rear end with posi, 3.91's
200 custom driveshaft
new ignition components/dist 300ish

so basically you can run 14's for another 1900-2300 plus a ton of elbow grease.

i dumped this setup for a 408 stroker, (4000 motor by itself, 900 ATI converter)....to run low 11's,

long story short, you're best bet is a mild 318 or 360 swap if you want any form of (performance) on a budget...even with a milling, cam, super six intake, and all the sixer go fast parts, you're gonna still be driving a 14.50-16 second car pending your budget, fastest streetable /6 i've seen ran a 14.30, with a full bodied car, and that motor was worked, been racing a long time, built alot of mopars...smallblock is the way to go.

You need to talk to Tom Wolfe (Shaker223) whose basically stock 225-inch /6 engine-with a Buick Turbo in a 3300-pound '70 Dart ran 12.95.

His car had a 225 with a 904 and stock converter, stock head, stock 225 cam, and a stock exhaust manifold with a turbo flange welded to it (NO header). I think you are selling these turbocharged basically stock slant 6s way short on how they can perform compared to a stock 340.

I never saw a stock 340 run faster than 14.40s, and I HAD one.

Tom's /6 was a lot faster than that (12.95) and had minimal mods (runs 11-flat into a 15mph headwind, now...)

I'm of the opinion that an A-body turbocharged /6 with only about $2,000 in mods can run mid 11s. I am not sure you can do that with a 340/360.:read2:
 
If it makes anybody feel better, I scrapped my plans for a 451 stroker to go with a slant.
 
Can't argue with any of those points, but still, more people will be around the hood of a slant powered hot rod than any other at a car show...simply because they are something different.

I will agree that was very true when I had the \6 in my car, but I didn't get the driving satisfaction that I do from the 360. I even had a sticker on the valve cover of the slant 6 that stated; "This is not Your Grandma's Slant 6". But after a year or so of hanging around the car waiting for folks to go "Wow" when they saw the built \6 it was time to build an engine that had enough power to scare the crap out of me! :)

I hear ya, Dave. ...and a real nice car you have, too.

FYI, RabidScott, I'm a dyed-in-the-wool slant loyalist, and I'm sick and tired of V8 guys insisting that every slant should be replaced with a small-block (especially in a so-called slant six forum like this).

HOWEVER, I'm also sick of slant newbies asking how to make their stock slant a Honda-killer (usually on a limited budget). If you have to ask, you probably don't have the resources to do so.

I LOVE my slant, but if the goal is to beat up on your average, modern import, hopping-up a slant will leave most folks unfamiliar with slants VERY disappointed, and they end up swapping in a V8 anyway (or getting another car altogether). Making slants fast takes more time, money, experience, experimentation and patience than a V8 swap. Simple as that.

What most V8 guys don't seem to get is that making as much power as cheaply as possible isn't everybody's goal. People who love slants don't normally have that "never enough power" syndrome (Slantzilla and a few others excluded :) ). Some of just like being different. If I could figure out how to get that through the heads of the V8 pests who constantly insist on an engine swap, maybe they'd leave us alone for a while. But I doubt it.

But just because someone HAS a slant doesn't mean a slant is right for them. It takes a passion to work with these engines. My comment was to save the OP some time and effort if that's not the case. If it is, he's not going to get the answer in single forum post.
 
I agree, you have to have a passion for the slants and making a ridiculous amount of power out of a slant is not a cheap overnight bolt on. However if you want to have an amazingly reliable engine that still gets good gas mileage then you want a slant. I have an 83 D150 pickup with a slant and a granny low 4 speed with the super six setup and as long as I stay under 70mph I get about 18mpg in it. ON TOP of the fact that some dick drained my oil when I left it at the bar one night and I drove it almost 60 miles before I found out that it had been drained because aforementioned dickhead brought an oil pan to make sure I didn't notice that it had been drained. I found out then added oil back to the motor and it is still running strong. That is why I love slants and I will stand by them. They are beautifully engineered motors that will stand the test of time unlike the new throw away POS Hundas that crap out at 100k miles.

DING, WE HAVE A WINNER! :cheers:








Oh yeah I would also just like to say to anyone that is offended......

Well here's the thing too, i have always hated v6's, and inline 4's.
So inline 6's aint my thing really. I only tolerated the slant 6 because it was a legend.

But i'm a big block v8 guy. I would slam a 426 Hemi in ANYTHING(well any mopar) if i could. Smallest v8 i would ever use is a 318.
 
Well, for a brief moment, I'll try to stick to the origional question. Cheapest way, 1: gears. Slants come with lousy gears for acceleration, 2.94's in the ones I had. If you are really cheap, (like me), a 60's International Scout (model 80) has almost the same track as an A body, the perches are even close enough to work. They come with a 4.27 gear ratio. With the help of a lift, I swapped one in in a little over an hour, and WOW, what a difference. Later I milled .100" off the head, (at least lap the valves to make sure they are sealing), added a 2 barrel, and had a reasonably "snappy" car. The 5.0 Camaro's were popular around here at the time, and I never even came close to getting beat by one. Not saying much, but there it is.

That said.... I stuffed a bone stock, $100 '65 383 2 bbl into a 4 door '72 Valiant, with the only power adder being a $30 iron 4 bbl intake, it ran in the 14's at 94 mph. using only 1st and 2nd gear due to the 2.76 rear gears. It got 20 Mpg, and was my daily driver for 4 years. Fast with a Slant will cost some jingle, unless you really can turbo one as cheaply as they say. I'm following a turbo /6 build right now as it interests me alot.
 
You can do a lot with nitrous but the orignal poster siad he didn't want to use nitous. Also, headers, 4bl intake and 4bbl for a \6 is going to be close to a thousand bucks not to mention the $400 or so for a basic nitrous set up. That is close to the cost of a sb swap.

Building a \6 to make v8 levels of power is something you have to want to do, its not going to be cost effective compared to an engine swap. I will try and dig the photos out tonight and post them. I know a guy that built a multi-point fuel injected and turbo charged \6 for a 39 Willys pick-up he built for his shop truck. Even that engine doesn't have the power of a mildly warmed over sb but for a shop truck its perfect. This guy also has a blown hemi in a 41 Willys pick-up that he uses to scare women and make small children cry.

Well here are some pictures of the turbo \6 I mentioned above. One correction; the engine is now in a 39 Studebaker pic-up not a 39 Willys that I mentioned.

The intake and header were fabricated by Rick and he uses a FAST efi controller to run it. The turbo is off a Buick turbo v6 and I believe the inter-cooler is from a Saab.

Enjoy the photos:

You just have to realize that if you're into something that isn't mainstream, you'll get comments like "put an 8 in it". You'll go nuts if you let it bother you. I used to modify VW Bug engines when I was younger, because they were cheaper to work on. So, I know how you feel. (The first car I drove after my warmed-over Bug was my 70 Challenger R/T w/ 383, 4 spd and 3.91 gears. I never went back!)
 
Dave thanks for posting the pics of the /6 with the Buick supercharger. I am convinced that when my V8 blows or wears out I will do something similar. I have loved /6's since my first car a 72 Gold Duster and have been talked out of doing a performance version of one but that won't work next time.
 
Hi Raleigh Rocket: You suggested milling a 225 head 0.100 to increase power. I want to mill my head but have a couple of other questions if you don't mind. My current compression is 8.2:1. What will 0.100 mill raise compression to? Can I use all stock valve train?
Peace,
Taz
 
For "Seat of the pants" power on a true budget start by getting rear end gears (3.55/3.91/4.10) a two barrel manifold and carb and a free flowing manifold (Dutra Duals or Headers) and single exhaust. That will have you back on the road in the shortest amount time and money. The other upgrades you can do later as money allows.
