Thanks guys! The car was dyno'd with a different carb on her. I wanted to start with a new, fresh one, so I ordered the same model & re jetted it to my elevation here in Vegas. I am not unhappy with the way the car performs, but if I can tweek it a little and make it a little better feeling, at least to me, that is always cool. I did already think about why did I not get a carb with mechanical secondaries. Most of the ones shown, at least on Jegs, were with vacume operated ones. Is there a conversion kit to change from the vacume to mechanical? I don't think I would go to that much trouble. I'll let you know how it goes!!

FYI The black spring, which is the heaviest & the one I have, shows on this chart, that on a 350 engine, the initial opening point is at 2720 RPM & shows " Not Fully Open" for top RPM! The other 6 springs show initial open at different RPM's as well as for top RPM's. Let me try to attach this chart.... Well, so much for the attachment! You can go to Jegs and find the Holley carb springs & click on the wrench symbol, which is the instruction sheet, you will see the chart there on the second page if you are interested!

Thanks again !!
