Now.
I have a 74 302 block ..it was in good shape but going .40 over with flat top Hypereutectic pistons.
stock crank was in good shape so polish and back in. rods are fine - will go with ARP bolts.I would use 289 or Boss 302 rods (5.155") and skim ~0.035"/0.040" of the piston- that will get you piston out the top of block ~0.010" @ TDC for a piston to head clearance ~0.035" with a 0.042 gasket. If your getting brave on camshaft deepen the valve pockets at same time.
new bearings all round.
I have a set of good worked a little 351 heads from 1970. going to bolt them on and see how they are. ( I know ...just get Aluminum heads ) These are free mind you.
This is the Cam I have Ford M-6250-312 matched with lifters and springs.
then a performer intake a holley carb.Do the lifter bore groove mod ( you can buy the tool from Comp Cams or build your own if you have access to a lathe ) , check for lifter rotation when you do your cam pre-assembly checks, run the cam in with some light springs at first start for 20/30 minutes with a straight 20 or 30 oil plus zddp additive and 2/2500 rpm.

then headers (not sure what yet)

thoughts?

Thanks all who chime in
