Isn't "Pro Systems" the carb company that claims to have a 4500 metering system on a 4150 carb

I heard that it was suppose to be a a good carb and thought of buying one for myself.

Why are you not keeping it ?

The carb was great, I had Pro-Systems do another carb for the new engine. BTW the carb is sold.

That is good to hear as I am considering one of their carbs for my new motor (540).

I still have a 950 QFT from my 496 that I never did like and instead spent some time working on an old 850dp that outperformed the QFT.

Good luck with your new build...... (is it posted somewhere here?)

Build is not on here. I built a 454 small block. Everything new except the cam. Dart Iron Eagle tall deck block, 18 degree Dart heads and intake, 712 lift and 280@50 on 106 CL with 4/7 swap 11-1 CR 2 inch headers. MSD E-Curve Dist. 1.65 T & D shaft mount rockers, Crower lifters. Should be in the 750-800 horse area, goes to dyno a week from wed.

I've bought 2 carbs from Patrick and found both were running rich as installed. Had to have both set up on chassis dyno to get correct A/F
