i bought the truck already built, heres what the previous owner had to say about the engine:

Block was fully prepped, bored .030, decked, align honed, etc..
Crank is stock with I think standard journals.
Stock rods shot peened, ARP bolts
New pistons – Don’t remember mfr or ring specs. Probably around 10:1.
Everything balanced
Cam is a GK A6HZ84P 230@.50, 284 adv / .470 109 CL. Notes indicate it degreed in at 107 and no additional offset.
MP lifters and pushrods
Roller chain, Melling HV pump, MP windage tray.

Heads are Mopar smog prepped by Hensley Racing in Knoxville, TN.
Glass bead, magnuflux, Milled .010, new guides, new seats, new locks, 10 degree retainers
2.02 / 1.60 valves
Don't remember chamber volume.
Unknown springs – maybe MP but don’t remember for sure.
Spring installed height 1.65 at 100 lbs seat pressure – Coil bind at 1.10
No additional machine work other than mill and cut for the 2.02 valves – no port work.

Never had it on the dyno, but similar engines I’ve built come in at around 375 hp.




ok, now my question is if i switch to edelbrock RPM heads (LA style) whats my compression ratio going to be? can i still run pump gas? also with an air gap intake (already on the truck) and a holley 750 with full length headers whats my power going to jump up to with those heads??
