On the dyno the car was running very lean. I beleive that is was because the intake manifold gaskets where sucking air and
oil from the lifter valley. It was very obvious when I changed the gaskets. The car made 323HP and 354 torque to the rear wheels through a toploader and jag rear. Torque curve was very broad and peaked at about 3500.
HP peakes at about 5300 where it remained the same until 6100. By 6500it was down almost 50HP. This is where I think I can get more. I think the car is under carburated with a 600CFM vacuum secondary holley. Looking for suggestions and experience on a larger carb for this package. Also, I was wondering how much HP I would actually see by going to roller rockers.
Suggestions?
Thanks
Rick
