Hello all , I am looking for Jon Spassov or Steve Ray. They built an engine and I have receipts but no details on the build. I cant reverse engineer anything without details on the build. Your help would be greatly appreciated. The engine is very well built procharged 496. BAM and other calcs show its producing 700-800hp. receipts show all the right stuff including custom JE pistons at 8.75 to 1 compression. JE has the specs that show 109 CC heads dished low compression built for blower use. I am trying to track down the cam specs etc. Its in a very fast Nordic Heat 28 I just bought. Thanks in advance.
