Are you going to modify it or just clean it up and run it that way?

I think he's going to find some dummy to go up there and install it with him. . .
 
We have two porjects going on Stu.  We are ralleying on a member on the 27th to put his engine back together.  And one of us is going to slide this sucker in.
 
We suggested he freshen up the motor, new front seals, timing chain, rear main seal, Valve seals, stuff like that.  The motor is a 72 and has been sitting around for a while now.
 
I don't know if he is going to do that or not.  If I had it here, I would do some head magic to it for him., slip a 4 BBL intake on and match the intake to the heads.  A little 550 would do wonders and he woulf get great gas mileage.

Don't forget to remove the pilot bushing,before the torque converter goes in!

Does that engine have some stiffer springs in it...possibly from being hooked to a manual transmission? I wonder if it has any other little goodies in it? I have "340ized" a couple of 318s with great results. I guess it all depends on what the OP wants out of his project.
 
It is too bad that they never made a 318 4 barrell manifold to match the smaller intake ports on the 318. I tried using a 340 cast iron intake on a 318 once. It did add a bit of torque but it did not work very well because this engine combination had too many mismatched components. After I figured out what the previous owner had done wrong I was able to make it work quite a bit better, but it never had the proper cam to take very much advantage of more air and fuel that the 340 manifold provided.

It amazes me why Chrysler did some things the way the did.  Like a larger rear bearing cap on the 318 and 340 than the 360.
 
Can you imagine what a 318 would be like if it was better matched?

I think it is more important to ask, why did the 360 end up with a smaller rear main cap? The 318 was built for truck work and it did just fine at that. On the other side, I totally agree that it was never turned into a hotter engine like the 302 Ford was. There are so many little questions which really don't have answers, it's like durability was the norm, build it yourself later for more if you want, more than enough material to make it more powerful and still hold up on the bottom. Compared to simple SBC or SBF, you don't have to worry about cap walk below 500hp, you don't have to worry about stock rods until 450hp range, punch the old 318 heads for stock 360 valves (1.88 over 1.78 and tulip the bowl) and you can add 75hp over stock, port match the heads and get a 318 specific 4bbl intake from Holley or Edelbrock and you are talking 145hp over stock (oops, add an RV level cam, you know, .440 lift, tiny still, but better than the .394inch stock cam). A heck of a lot can be done to the 318 than most realize, where a simple balance of the 2bbl stock engine will give around a 20percent across the board improvement in power, mileage,  and performance. And stock components sure beat the heck out of Ford, Chevy, BOP, and all Japanese engines. Heck, even the pre-Magnum roller engines have a ton of potential, and most all the parts swap without a problem (until they went electric fuel pump, etc.). And a four inch stroker crank will fit for a 390 cubic inch monster (+.030) if that is what you want, Ford can only go 347 from a 302 and Chevy go 383 from a 350. Goes for strength as far as I am concerned. In fact, I personally think a weak 318 is stronger than a weak 302 or 350.dana442010-03-08 00:30:54

I have to agree that the 318 is one of the best engines ever made. How long were they in production...50 years? That sure says a lot for the design and durability of this small block engine!


On a side note I have used a Scat crank kit in a 350 SBC to bring it out to a 396 CI displacement. The added stroke required some extra work relieving the block to accommodate the new parts and not all engine blocks will work. All forged parts made it a very strong engine.

And to think the engine went through some evolutions in that 50 years and still outlasted the competition

That's the whole point. I know stock for stock, the 318 will outlast any other engine I have witnessed stock survival. I had a 318 in my first 68 Charger. The original 318 had 265,000 miles on it (the kid used to make weekend trips to Mexico to buy stuff for a couple years, built up quite the mileage). The motor was pulled in favor of a 383, but the original 318, never opened, was honed, valve grind, rings and bearings, and stuck in of all things, a 71 Mustang and bracket raced in a 12.30 bracket consistently for a couple years. It took another 65,000miles of pounding before the engine, still running, was removed in favor of another 383 to bracket race (in the Mustang of course).

Yes, I have had much better luck for durability with the 318/360s I've
had compared to any  383/400/440s. of which I've had 6 or 7. 
200k is nothing for a SB. I don't dog 'em any more, so this one will
remain totally stock. It's a '70, not '72, so it has the higher
CR.  The 70 Barracuda it came out of was 318 stick and belonged to
an older woman!  8000 original miles!! That car is now living on
with a 44 6 Pack. under it's hood. Transported from OH to NY just as a
body donor, essentially.



Good question, I wonder how it differed spec-wise compared to one hooked to a 904 or 727.

I thought, the only diff was the timing.  But from the looks of those springs, who knows.  Maybe it was made on St Patricks day.
 
I want that flywheel and clutch.  LOL
