[GTO Karl]

71 T/A:

This time I will actually try to answer your question.

I do not believe at the level of performance you are at, that a change in carb will make a significant difference. I have run 118 mph with a basically stock 800 cfm Qjet on a Victor Dominator manifold. Most of the mods to my carb were for idle quality improvements for the cam I am running(about 10 degrees larger than yours).

I don't think a Holley would hurt, perhaps a well built one might run slightly better, but I think you could spend your money elsewhere. Your mph is in line with the et you are running, however, you have not mentioned whether you have a traction problem, or what your 60fts are.

Also, how much timing are you running, and what jets and metering rods are in the carb now? What altitude is the track you are running at?
