Re: 1970 402 BBC build

I'm building one right now hopefully 500hp and 500tq. I have a complete rotating assembly cast crank fresh turned .010 and forged pistons w/rings .030 for a 402 or .060 for a 396. I have a Lunati voodoo cam 218 228 @ .050 brand new was installed but never ran. I pulled it because I went with a hydraulic roller and steel crank and rods. If your interested pm me. 400-430hp would be easy with this set-up if the heads are right.
