don't get discouraged by all the negative 318 talk,it's still head and shoulders above the 360.When they dropped the 340 in favor of the 360 it was a cold day at mopar.With it's long stroke and short rod ratio all they created was a pig.Not to say you can't create smething more out of it but why?If you want a fast drag car there are much cheaper ways of going about it without ruining aclassic car.The 318 has almost as much potential as a 340 and easier to come by.With the right cam along with a good dual plane intake and the right gears and 904 tranny (not 727)it has less rotating mass,it will spank a 360.The 318 and 340 rev quicker and in a light A-body it's by far the best combo buck for buck.I run a 1995 magnum 318 with xe264 cam with a power-product intake with Edelbock 750 and otherwise stock 9.5 comp.ratio motor in my 66 valiant along with a turboaction 904 and get 20+ highway and will run 13's all day long.Maybe not the fastest but thats not why I built her,she brings back memories of my duster and cudas of the past and looks good to boot.So don't give up your thoughts about doing a 318,I think you'll be very pleased with what you end up with.

Yes, the 360 was a pig in stock form as was the B block 400, but this was only due to low compression from the factory, nothing else. The rod ratio is 1.85 on 318 vs 1.71 for a 360. You'd never notice it in any street application and is still better than a SB Chevy. Less rotatating mass? Sure, the smaller the engine, the less the rotating mass you'll have, hence the availibilty of lightweight pistons and rods. Just because a 318 has less rotating mass doesn't mean I wouldn't drop a stroker B Block in my Duster.

What you've done is a great, sane build for a 318 and I applaud you for using a common sense approach. The only thing I would've done different is use a roller cam since you have a roller block.
