I’m getting an “honest” 370-380 from mine.
I’m sure I’ll forget something, but basically-
Crower 60242 cam
Original Intake gasket matched
96 heads cleaned up and lightly ported
Ultralight rods
Flat top pistons
Block zero decked
.027 Cometic head gaskets ,CR is at 9.6:1
Original Q-jet
Original distributor recurved
Oversized RARE manifolds and mandrel bent down pipes
RobbMc 550 fuel pump
Track times are in my signature. That’s granny shifting with my original Muncie
Honestly, if I were to do it all over again, I would have just stroked it.
