Suggestions for a 318 build
Just to give you a combo idea I have a 318 that I built that was in my cuda. I chassis dynoed the car at 301hp to the rear wheels. Should be close to 400 crank hp. I don't want to confuse you with the bottom end because it's a mutt. I posted it but ignore it. Just plan on between 9.0-9.5 - 1 compression and a stock displacement 318. with the cam, heads, and an air gap intake instead of a six pack like I used.
348cid
1970 318 block bored .025 over
.060 over 283 pistons with custom dishes and crank clearanced
3.58 stroke small journal cast crank from mopar rods cut to 2.100 journal
chevy eagle rods, 6.000 long, large journal
Rebuilt stock cast magnum heads with 2.02 intake 1.625 exhaust valves
Guide cut down for retainer clearance. Bowl hogged NO HAND WORK!!
I had Hughes engines redrill the intake pattern to use the older intake.
Lunati off the shelf cam 225 @ .050 duration .480 lift intake 225 @ .050 duration .480 lift exhaust 108 deg LSA Installed straight up. The magnums use a 1.6 rocker from the factory. It increases the lift to .512
Stock rocker gear and mopar perfromance head swap pushrods.
Six pack intake and carbs
TTI headers and TTI 2.5" exhaust
Stock windage tray
This engine ran beautifully!!! It has a little idol lope, ok vaccume (you might have to use a vaccume accumulator can for power brakes), and did the boogey very well with 4.10s infact my father liked it soo much when I decided to put he hemi in my cuda he wanted the entire setup for his 67 coronet convertible.
