I like the 750 holley, on my 351W. Running vac sec set at 2400, also put the secondary kit on to rejet. Using 80 in the sec and 76 in the prim. I think I will go 78 on the prim this spring. Also a 50 pump helps. Plugs look very good.
Have a ??. What gas are you guys using with high comp and carb? I am at 10:5 or 11. This motor likes a lot of advance thus need some high octane?
Anyone use a mix of high octane-lead with Sunnoco Ultra? I am can buy cam 2 110 at a local station.
Thanks,
