I know who built the car and I know the pervious owner quite well. And it's funny how you know exactly what car I'm talking about and I didn't even mention a name. "do the math" there is no way your car could be making close to 400 on that setup and on 12psi. Just saying. On 12psi I don't dout it making like 320 maybe 340 but it's only a piston rod motor with bolt ons. Who are you kidding. But hey I made my point. I'll leave you alone. I never had a problem with the car or the owner! Just wanted to clear up the whole "ruffly 400" thing
