Hello there. I'm new to the site and figured I'd check to see what I could learn here. I've got a sbc 400 that I've decided to build to put in my wife's Firebird. It's going .030" over and the cam I'm using has a lift of .462"I and .480"L...the duration is 218/226@.050". It's actually a comp cams 4x4 xtreme energy cam but it works for what I'm aiming for...torque. My question is, or questions are...what else do I need to bolt to this puppy based on the cam/engine. Heads, intake, compression ratio, etc.?
