Sounds like a good combo with the 1.5 rockers. I had a Edelbrock 750 but couldn't get the thing tuned...I didn't want it to beat me but I gave in and went with the 650.
No no, stock Magnum heads, 1.6 ratio.
With the 1.6, on the [email protected] LA Hyd cam above, the lift toes to .539, IIRC. Or something like that. I’ll have to find the card. It’s an old Crane grind on a 108, single pattern.
