Local guy, pimp car looks stock. Made something like 580 on the stock motor, put some forged internals in. Should make 730-750whp:carnut stock cubes
I did the heads up, last week. Really happy with them, one casting was a little rough but finished up good. Stock valves, put a good valve job in them with a serdi. Should make some killer power.

roughed out, port came to the VJ nice. stock valve, this was @ 90/88% throat size at that time fit.

interested in doing something non ls1?

The intake rocker arm bolt. I know someone that ported a set of these 243 castings without removing the bolt pocket, and got the head to move 320cfm. But it changes other areas of the port, and causes some airspeed issues. That its better not to have to deal with just removing it and setting it up without it. This set didn’t get on a bench, this was on a budget. The car will be going on a dyno, if that means anything :slight_smile:

12

what do you want, the engine to do?
