Paul:

This brings up a question to me:  how do stock eliminators (required to be
TOTALLY stock with the exception of blue printing, balancing and headers)
make enough power to be in the 9 sec. range with QJ's if the above is
accurate?  Just a question. You have much more knowledge about carburators
than I do.
