seen idk how many young folks come on here asking how to get a lil spunk outta a 318 to be told and preached how wrong it is to even consider hopping up a 318, most seem to fall off and drift away! not every body looking for all out race type of builds! i think a 350 hp 318 in a light A body might be a bit much for some pimple faced 17 year old to start with!! but that get told no,..build 600 hp or forget it,..thats skerry,..how bad things happen we wish didnt! let them build a 318,..thrash it out,..learn to do a burn out,..how to drive somptin with some power, not all that power!! thatll keep them in the hobby longer and teach them basic stuff too!! not every body needs a stroker or aluminum heads ether come to think of it! DWB!
might be a bit much for a 50 year old expert too.

Yeah I hear tell those Challenger Hellcats were a beast when they came out. People would punch it at a roll and wreck them at highway speed...

I don't imagine some broke kid was buying them...:)

Sort of like the Little Red Express in rainy areas. Someone would punch it in a wet corner and the 360's torque would swap ends and many crashed.
 
We don't need some dorky thread on the internet to settle this. We need a drag strip.
 
Can we put a fork in this thing by just agreeing that they will cost EXACTLY the same except for the cost of the block. If a car had a 340 in it that needed rebuilding would a guy go buy a 318 core because they are cheaper to build? What component is more expensive for a 340 than it is for a 318?


I just learned that on Youtube and Instagram there is this thing called "Engagement Rate". It is a metric that is used to determine how much engagement a user is getting from other users. I have read that it is something that can be addictive. Sometimes people will post controversial content to get more hits because in the algorithm, every engagement counts.

Here it would equate to someone who gets a dopamine hit from getting "likes" or 'thanks" on their posts or from how many pages one of their threads can go.

For such a simple topic the OP seems to relish that the thread lasted this far and over 100 people have voted.
Oh, and wouldn't you know it, the OP is a YouTuber. Hmm. Addicted to engagement?

I really like 318WR but Jesus H. Chrysler! Will it ever stop? A much better comparison would have been 3.58 stroke vs. 3.31". Or 3.79" stroke vs. 4.00". Closed chamber head vs. Open?

Well, my argument is FORGED 318 pistons cost more than FORGED 340 pistons.....and they do. So there's "SOME" of the leverage lost "RIGHT THERE". Here's the least expensive of the two choices.

340:
DODGE Speed Pro L-2316F 30 Speed-Pro Forged Pistons | Summit Racing

318:
DODGE ICON IC844-030 ICON Premium Forged Pistons | Summit Racing

Again, nobody can tell me my intents. I can tell you my intents and whether you believe them or not it's up to you. I remember when I bought a complete 340 for 125 bucks, ran well when pulled. That was a good deal. Getting a 340 in those days made absolutely perfect sense, even if you paid 300. But I'll state it again.... collectors and class racers has turned it into a lot more $$$$. All I was asking is have we reached the time in our Mopar world where even on a 3k budget is the 318 the faster engine ??? If you think 340 is still the bang for the buck, cool~! Unfortunately, 340 "only" guys have found 101 reasons of why it's all wrong, including me wanting attention LOL :D :D. Yet, all they have to do is just answer the question of "yes" or "no". If they even want to explain all their "why's", then post up!! But to all those that accuse me of "starting controversy" or "wanting attention"... LOL Sheez, really? Not a clue, simply not a clue.

  • First of all, fair market value on a 340 bare block that is known good will run you about 700-800 bucks. You now have about 2200 to buy heads, rods, crank, cam, lifters, valve springs, gaskets, intake, and carb. Good luck with that.
  • 2nd of all, if you want a good core motor, fair market value will run ya about 1400-1500. Now you have a foundation, but I doubt it will include forged pistons. I think you are talking gaskets, cam/lifters/springs/heads redone, intake/carb and a re-ring kit.
  • For the "free" running 318, I'm not buying crank, rods. Good aluminum heads, cam kit, 300 dollar set of pistons, might even go standard bore. I could go on and on, but the point is I think the 318 wins the race.

I assume the 300 dollar pistons are KB hypers, correct?

I am having a 422" 340 built by IMM and just had a 328" screwed together for my D100. I would have loved to do my own 318 but I have no enclosed shop space and Momma won't let me do it in the kitchen.
I guess you could say I am just an LA guy.
Here's the deal, I bought the 340 for $300 and it needed a sleeve. A few hundred. If you aren't afraid of a .040+ 340 block then you can get into the 340 game for not a whole lot more than a 318. Yes, prices on standard bore 340's are stupid but you are comparing the low side of 318 prices (free?) and the high side of 340 block prices (standard bore blocks?) to get the answers YOU want.

And your $3000 budget? C'mon man. If you got a $3000 budget you better be buying a damn gasket set, rings, bearings, Summit cam, and freshening that sucker up. It's 2021 ol' son. You aint getting very far on ANYTHING with $3000.

The most money I have in an engine, including the price of the engine, in my cars today is 1450, and it has aluminum heads. I think 3k would be "unlimited shopping"... LOL

You have a good imagination.

How much of that stuff did you get second hand, from a deal, have already, traded for, robbed off anther car ........
Take that $1550 you saved and you could go find a $400 340 that needed one sleeve and spend $150 on that and you could have bought those cheaper 340 pistons. You still have $1000 for a Pentastar shaped air cleaner and a foot print gas pedal.
 
Post 1362, friend. I don't imagine too much before I make it a reality. :)

What I'm saying is you are imagining scenarios where you would have to face the dilemma of spending $2000 on a 340 or going with a free 318. I already told you there was $400 340 blocks still being sold. I bought one. You're imagining that they all cost $700-$800.

730 aluminum the pair of heads brand new fully loaded shipped to my door. 400 bucks for the short block 360, including cam/lifters. 2nd hand RPM intake for fair market value (can't remember, but maybe 150 ??), 750 DP 2nd hand, maybe 150 ??

ok, an unusually great deal is cool !! We all want them. But the best deal I could find locally on a 340, I posted in the first post. 1500 intake to pan, good core.
 
Now you're bringing 360 into the chat? I remember a couple 25 or so pages ago you were trying to keep the 360 out of it.
In response to YOUR post 1361 where you said 3k is a shortcoming so to speak. It's 2021. I just said my most expensive motor i put together in any of my classic cars was 1450, not even half of the 3k budget. I just listed the parts.
 
When you really look at the "Horsepower PER Cubic Inch", the 340 is really low on the scale. Even the 2.2 Shelby and the 273 4bbl have more HP per cube.
And we all know the 360 E58 in the LRT was more than 225 HP....

So if you didn't get the 360 and found a $400 340 + $150 sleeve you would only have $2000 or less into it. Still under $3000. Your resale would be much more higher for it as well.

  • Resale is another whole subject. 340 has the market, which is why the 318 can be competition on a 3k budget.
  • 400 include crank, rods, pistons and all?? Just say'n, I could find a 440 6 pack at a barn sell for 50 bucks. We all know those great deals do come up now and then, but it's not fair market value.

It is known that Chrysler under rated those numbers. Mopar Manipulatin - Hotrod Magazine Aug/Sep '69 (I believe?) dispells that rating.

I think gross would actually be about 310 on a 340. I think they got the Net HP correct, about 245.
