The specs are below....although my question is really about who is the best supplier.

416" 340 +30
4" Steel crank, H-beam
Dynoed at 575hp@6500, 550lbs torque @4700
Ported J Heads flowing approximately 270 @.600"
Gary Stinnet HP950 on Super Victor
Cam: 627"/637" 276/281 @.050"
3300lb A-Body
Low gear 904
5.13 Dana
4-link
16 x 33 GYs
Stock front suspension
10.40 @125.00
1.37 60'

The car works well the way it is currently setup. However, I am looking to push it over 600hp to gain mph when running Super Street and a couple tenths padding on a 10.60 index.
