looks good.

what pistons do you have? flat tops? dished? with 64 cc heads on a 383 with flat top pistons you should have near stock compression.

if you're gonna spray get bigger injectors. I have 37s and I don't plan on any forced induction.

well the wet kits not going to be effected by the injector size.
but if your buying some get some bigger ones, 30# will be close to maxed with stock fuel pressure

i would skip that part, and just get a 9 inch or 12 bolt if you really plan on racing it.
im sure the stock rear end will hold for awhile, well maybe till you sprayed it with some good tires. lol

also i would wait till you get the heads flowed, then have someone make a custom cam for it.

I don't know what porting is done on your AFR heads but if they are the full competition series CNC porting from AFR with no additional hand work, I'd say you could expect 385-400rwhp with a spot on tune and 6spd car NA.

Well the rear end is already in, when I break it I'll get the 12 bolt. The heads are CNC Competion ports. I have 6 on the floor. Gonna order Spec stage 3 with the steal fly wheel. The pistons are flat top.
