Right off hand the seperation looks very wide for a naturally aspirated setup, but need to know a lot more about your combo - heads, exhaust, intake, carb, stall, gearing, weight, transmission, fuel, nitrous use, etc. Clay

Never mind my previous postk, I found your other thread. The heads you have are hurting the outright power you need to get down track. I think you can have a really torquey setup but 11.90's are going to be tough. I would like to see some video at the track also as you might benefit from changing other things on the car. Stall could maybe be a bit lower and you could probably lose some gear. Really need to work on the total package to get the most out of what you have. Start with the camshaft you have and run it as is and get some information to work with. Anything you buy now is a stab so you might as well try what you have and then you can learn and spend your money more effeciently. Clay

If you're not doing the head work yourself, get some quotes. It might be more cost effective to get another set of better flowing heads.

A bigger cam would likely be in order.
