I think

Because you build what you like have or want, I think having a,goal of 3k unrealistic, at least for me. I'm not going to but the cheapest parts just because of cost. I'm going to buy pistons and heads that give me the parameters I want, same with rods, bearings etc.. I don't see being happy with an engine just because I only had 3k in it and it ran 13.50s. If I had to build a small block it would be a early 360 block with 340 pistons for 372 cubes with a stock crank.
It's funny how the logical choice for a sbm is removed from the conversation.
3k engine to go 13.5's ???? :realcrazy:
Anyways, the 5.9 is left out for reasons posted in post 19. If it was cut and dried, it wouldn't be any fun now would it ???

It's just one more bs thread that has no meaning, 3k for a 318 or 5k to go 10s, just wacked.
 
Why can’t you guy’s get the 318 vs 340 thing? Even if 360 was part of the choice’s, I can buy and build a teener with 3 grand that will stomp your 360 you bought and built for 3 grand.
Put down the crack pipe
 
Well
here's what you do;
buy the early hi compression 340; sell the heads, sell the used cam.
Install any half-decent junkyard heads and a free 318 cam .
Now you have a big bore 318 with a serious bottom-end that will burn rubber with 3.23s to say 80 mph or more.
I have done this and highly recommend it.
I got the 340 for free because it had sat in the junkyard with the intake off, and some of the pistons were seriously pitted; no big deal. I got the 318 heads for swapping the 340 junk onto a buddys 69 Satellite 318. So I was into this thing for gaskets, rings, and a few hours work.
And, I had to buy some headers to stuff it into my 65 Valiant wagon.
And I had to buy a V8 904/ with attached 273 to get the power out the back door. Plus I wanted the adjustable rocker gear. So that was another $50.
The thing went like a raped ape; even with the 2bbl top end on it that also came from the Satellite.
That was about 1974, and was the most fun I ever had, until 1999 when I built my current ride.

Thats almost funny……….. almost, but not really.
 
I agree, it wasn’t. Common sense wasn’t either. Why is that so hard??
Well, I guess I could say it wouldn't be common sense to click on a thread that plainly states 318 vs 340, and 1st post said 360's not included... and bring up 360. Yes, the world is aware you can buy a good running 5.9 magnum for 300-450 dollars. It's why i left it out of the discussion.

all well and good,But I have five 318 engines sitting here that I would love to unload on someone.
But There is a waiting list should I decide to sell the 340 engines.

For sure 340's bring the money. When it comes to resale, no contest. The very reason for this thread. On a modest budget of per say 3k, is the 318 the smarter choice if a person doesn't have an engine ?? speaking of performance, of course
 
I agree you can put money into any engine and make it go be it chevy ford or dodge, and i have several 318 engine cars that run very well. but I am old school and drove the 340' in the day, and I still have one. The saying in 1970 was a dummy can drive a 340 and win 90% of the time. But it took skill to race well with any 383 roadrunner or a 440 GTX for that matter. I saw many a dart wax 440 B bodies because the owners did not know how to control them. To me the 340 Dart was like riding a 900 Z-1 kawasaki. it was a pussycat at an Idle, but one twist of the throttle and that bike was gone!
back then the street was not like the track, lots of dummies who thought they were fast.
The fastest did the most with the least. But I like your post, anything that keeps the Interest
up in the old mopars is fine with me.

You sure put up a good hissy fit...
 
If a 318 is doomed to never equal and or out power 340/360 cause of it's slightly smaller bore 22/42 cid difference. A 340/360 should never come close to a 440 80-100 more cid and a 340/360 bore don't even come close to a 440's, so why waste your time with any small block?? Why?? cause every engine has a reasonable power ability and there's a lot of overlap, most performance NA engine's are gonna be 0.9-1.4 hp per cid and even more for some people. For a 318 250-350 hp ain't that big of deal, 350-450 hp is very do able but most are gonna go with bigger cid and very few are gonna try the 450-650 hp even most 340/360 guys won't try with stock stroke cause rpm needed gets to high for most.

I don't see how people think a 0.060" 328 10.5:1 cr zero decked eddy head and 750 airgap with a 235 ish cam with .500-.550 lift 4000 stall and 4.56 gear ain't gonna take down a lot of cars on the street, or what ever well built 318 someone does, sure there will always be faster cars but that's the case almost 99.99% time with what ever engine you run.
 
i run a 410 stroker in my car . 360 magnum based. but if i was doing a car that was more show than go, i would be temped to find a 318 magnum out of a truck. would have to be way cheaper than a 360 and set it up for peppy performance with decent gas milage. Love my 410 but she sucks the gas!!!

I have personally seen two 318 cars WITH 2 barrel carbs run 11.70's in the quarter mile and one of them was a B body.

That's impressive !! Must have been like a stock car (circle track) engine ?? 2 bbl as in stock car 2bbl ? That would be fun, certainly not the norm and I like that !

NHRA stock eliminator
cheater cam .462 lift 336 duration intake, .473 lift 348 duration exhaust on 108 centerline
5.88 gears
stock carb
fenderwell headers
full interior, bench seat.
I believe this car has been a race car since new, showed 30,000 some miles on the clock.
I'm pretty sure this motor was built by a stock eliminator specialist back in the day.
I tried to get as much out of the guy as I could cause when I saw the 2 barrel carb, I knew it had to be a 318 which the guy confirmed.
I was stunned to say the least.

I'll take one of those stickers.
 
well, I thought the title and opening post was pretty clear. Folks will throw out anything but what the thread is about, regardless. If it was about stock stroke 360's, somebody by post 4 would say "why not 408". It's who we are here.. unfortunately. I really thought this subject was worth the conversation. I'd take the 340 in a heart beat both for free. But, if I had to buy and build, would a guy be better off with a 318? Even up to 4k to spend?? Just food for thought.... which motor goes faster ??

Yeah cause you can get a 318 for free. There's been a few here on the forum offered for free. Very recently.

I've gone 12.90s with a 600 dollar engine.

Exactly. 340 has 22 extra cubes and better heads, intake, cam, rods and exhaust manifolds, but you can't find a cheap 340 any more (I'm old enough to remember when you could). 318's, on the other hand - well, one of my Studebaker friends ended up with a 70 Fury with what appeared to be a complete, probably good running 318. He thought he'd be able to sell the motor for a few $$$. Couldn't even give it away. Finally just scrapped the whole car.

If you don't already have either motor, then the 318 is so much cheaper to get into than a 340 that it makes more sense to start with the 318 - which was the point of this discussion.

On the other hand, if you already have a 340 and a 318, starting with the 340 makes more sense. Dollar for dollar, you'll get more out of the 340. Especially if you're on a budget, because it's not just the extra 22 cubes, but also that with a 340 you're starting with better intake, heads, cam, etc.

But it's fair to point out that 360's are still cheap, so unless I already had a good 318 sitting around, I'd start with that.
