270@500 is REALLY good for a LT1 casting. 185 however, is a little weak. I'd expect to see around 200ish @ .500 on the exhaust side.

Did you do this port work yourself?? What were your overall flow numbers???

Yo Wayne. I see you are from DE. I think I talked to you before...anyway you should come to the F-body shootout at MIR raceway tomorrow. There will be lots of f-bodies in attendance and will be a fun time. BTW, LT4 heads flow ~240cfm out of the box..not sure on exhaust numbers.

Matt -

You bet I'd be there had I not blown my engine last weekend. Thats why I'm all over this sight trying to construct a new stroker setup. I should be on the road in a couple weeks so let me know how it goes...
