Did you read the part about them being on a 464cu/in tall deck small block? Nice heads if your motor can use them, most forum members wont be able to use them.....Or maybe I'm wrong as I tend to go on the small side when it comes to port volumes on my builds. My low 12 second 355 motor had 175cc intakes and a 650 Holley on it and I'm sure none of these parts would be recommended by most forum " experts " for a low 12 second car running 118MPH trap speeds.

The car body is a C4 that's about as far as I would go. It is a track prepped Ford 9 inch rear end 1/4 mile race car and should be in the low 9's for something to brag about.

I would agree if not for the 7000+DA.

the altitude correction factor would change things. N.H.R.A has a chart.

There is also several correction calculators on the web, dragvette & wallace racing are a couple to name a few.
