Which carb should I go with ? Ok I do not know alot about carbs and far from a pro. I currently have a 91 s10 with a built roller 355 chevy, 10.1-1CR, brodix ik200 heads, 1.52 roller rockers, rpm air intake it's been gasket matched, comp cams 282 extreme energy cam, 3000 stall, 3.73 gears, 100-200shot of nitrous and a 650 holley street avenger.
I am looking upgrade the my carb without breaking the bank. I called holley and they suggested this carb : 4150 Street HP Carburetor
750 cfm
"Double Pumper" Mechanical Secondaries
More info on Holley 0-82751 no choke
I called my local speedshop and they had this carb for a few bucks more and said it is lighter with see thru fuel levels and 4 way idle screws :
Proform #778-67200
Race Series Mech Secondary Carb
Now I have been searching the web to get more info about the proform carb and not getting much luck. Any suggestions on which carb I should get or if there is another in the same price range I should consider. BTW the speedshop ordered both carbs so I can compare them in person but did not try to steer me in either direction

The holley would be better for you, but the Pro Form is a PITA at time unless you can tune really well. It is not easy for someone that is not a general carb tuner. Get the holley.

Thanks, I guess holley it is. You just confirmed what little reading I have found about proform is true. They are good carbs but difficult to tune, some even said they had to get a shop to tune it
I'll just get the holley to be safe, I am a fuel injection guy learning this carb thing and don't ned the headaches plus everyone I know over 50 can tune a holley

my vote is for holley hp street line, or the regular hp line.
they are awesome carbs out the box and require almost no tuning.
the street hp 750 recommended is what u need
