I need cam advice. Even a tech advisor from lunati didn't seem to help much. I have a weekend drivin 84 cutlass.3.73 gears. Building a 357,flat tops.vortec heads (906) I'm wanting 400+hp , strong torque as my car is fairly heavy with 24x10's all around I'm not much worried about top end power since my car will only see the street. I plan to machine the guide bosses on the heads if needed. I'm also wanting a nice lopey idle. Lunati recommended 262/268 .468"/.489" I've read the vortecs want longer on the exhaust so that makes some sense just doesn't seem like a very big cam. Any advice?
