    Default Proform 1050 carb?

    I was able to pick up a Proform 1050 carb recently and I want to start with the original jets, PV's, etc. for a tuning baseline. The kid I bought it from changed everything all around for his application and "can't remember" what the stock sizes were. I am having trouble finding any specs online. Does anyone know what jets etc came in this carb stock? It looks like it might have had jet extensions judging from a notched float, but those are missing, and the PV's and jets are way off (he had this on his 350 street motor). Any help here would be appreciated.

    go to mortec.com , scroll down to where it shows carb specs, look up a similar holley with the same size, run that jetting as a base tune up

    Dare to be different, if it turns out great you can claim you planned it that way.

    Mortec doesn't have any listings for a 4150 1050CFM Carb.

    Holley has that info on their website. Need the full model number from the carb which is stamped on top of the carb body.

    What's the specs on the motor anyways. Most of the 1050s are either set up square at like 92s which probably isn't your case since it has PVs so you probably have progressive linkage and something like 82/88s or something like that for stock. Either way look it up it will give you the stock jetting and pv info and everything else you need once you figure out how to decipher it.

    I was just wondering how they get 1050 out of a 4150 throttle body. I see Quick Fuel has them too.
