Mr. Rahn that is one very clean and impressive engine. No really fancy parts, just ones that will do the job very well for a long time. Nice to see that you don't need the C heads, shaft rockers and such to make almost 1000hp.

No, but it helps if you want to make 1200...

Very cool build Mr. Rahn.... Car runs OK too...
