Re: L-72, final assembly
If the heads are virgin, I would seriously doubt they are 108cc...which I believe is what the AMA spec is on them. That's what you want them to be, but from the factory they left plenty of room.
As for who makes the GM cams, I was thinking it was Crane, but you 2 said Comp, so it very well could be. All I know is that our next one will come from the GMPP book. Pete, any idea who grinds GM's cams?
