Now needing 360 build ideas!!

If you can get a reputable machine shop to check them over I'd save $1200 and go with the iron heads. Some cast or KB pistons will be fine too. Stick it at 9.5 or so compression and maybe use some ARP rod bolts but honestly guys ran stock bolts for 30+ years with no problems so...

Yeah refresh that bottom end, cam it, intake, carb, alittle head work and exhaust (can do headers but dang are they a PITA and really manifolds will take you into the 13's easily). Save your $ here for the next engine IMHO.
