Yeah it is the GT40 Lower section of the intake only. The KB sits on that.
I have a set of roller rockers. I know there are different things I could do at with it, but it is almost 10 years old without a breakdown and it is very reliable. That alone is just fine with me. I can smoke the tires up to 4th gear which can get scary if not careful. E ca is what the engine builder suggested at the time. I am only running 6PSI. Plan to get a Snow Methanol injection cooler and put it in this winter. Should be good for a couple more HP.
Hey it is just a fun car. I'm not trying to kill myself in it!

here is the engine.....
