1970 Trans Am Project

Sweet! Do you have a time frame on that build? Ive thought seriously about staying with a 400 and doing almost the same thing. I had Dave@ SD performance spec me a 400 build a year or so ago. It used his stump puller hydraulic roller and 290cfm KRE D ports and an RPM intake. He was claiming they usually end up in the 500-525hp range and 525-550 ft lbs of tq with a long flat curve.

the time frame on my build is about six to eight months. jim lehart at Central Virginia machine services is building the engine for me. he is a very popular pontiac builder and there is a little bit of a wait but he does a great job.last year he built a 461 stroker for my 69 GTO and it is insane.



I am sure SD performance would also build a very nice engine. I have those kre heads on my 461. we went with the 246/248 can and ported the heads to 330 CFM and used the Torker 2 intake.
