rohrt, may be wrong, but I think what Tom was getting at was with the edlebrock carb and the engine set up for a 2bbl, the carb would dump to much fuel for the engine. Maybe not as much of a HP loss but still very inefficent, not any gain either.
From everything I have gathered, the stock pontiac intake with a well tuned q-jet outperforms any aftermarket part up to 5500, and the performer intake will either slightly drop or not change at all the performance.
