I've talked about this engine asking q's before on here. Its a 504 chevy big block. My builder is assembling so the details are at his shop. I trust his knowledge, he used to work on early nitro cars in the 60's or 70's. He's good. The heads were a cnc pro comp Aussie head. I actually talked with a few guys who use these heads seen it myself and they were fine but when my builder torqued the studs they pulled. One of them deals. Glad he caught it and said no fixin, no glue no way.
The bottom end is all forged eagle, mahle pistons,. 4 and 3-8 stroke, jesel rockers 700 some lift cam. All good stuff no scrimping. I have been around long enough to know that ofcourse brodix 18 degree and dart and so on are great but what about these 320 freedom fighter patriot heads. Rec ports. Were also looking at a set of oval port trick flows but really want the big numbers and the engine is designed to run rec port, opinions please. motor will make over 700 on pump gas
