it may be possible, but i can't say for sure.
it looks like the intake valve size is the only difference ?
Hot Heads would be the guys to ask, i would think.
every time these early engines come up, it makes me think i need to build one of the 392's i have on the rack.
then reality sets in, and i realize my "shopping days are fast running out"................
so lately, i've been contemplating selling them, not because i have to, or they would be expensive to build, but because of health issues that require the funds to go there instead.
please keep us posted on this topic if you could.
