I'm running cam A right now. Lunati wanted it installed at 104, it came out to104.5, so I left it right there. 5.5 degrees advanced. Makes good power, idles nice at 1150 with 12 inches vacuum. 185 cranking psi.
Heads are cnc Indy/RHS, flowed 296 at .600, but down to 292 at .650. My combo made 562 on a real, calibrated, local dyno that ain't customer friendly. My guy says it's accurate and I believe him. It made 488 on a chassis dyno (tuner shop)4 months later and 45 miles away. So please let's not do the dyno dance....numbers are numbers.
Just researching to pick a cam for my combo I'm building this winter. Only difference is I will be using Edelbrocks with Hughes full CNC deal. Really trying to get closer to 600. I think the heads will really help, but more cam can't hurt. I run a 4 speed with 4.10 gear.
I've read LSA wider than 108 is a power killer. My machinist feels the same. Seems like back in the good Ole days i never even heard of anything wider than 106. Just hoping to get a better understanding of LSA.
