I have ran C&S carbs for 10 years how in the world are you running 105-106 jets.Engine temp should be around 180-195 for a alky motor to run good.I have ran 94 front 96 rear in all my carbs.I now use a C&S aerosol billet carb real sweet !!I run a 377 with a 630 lift roller cam and Brodix alum heads at 7300-7500 RPM.With a Edelbrach 1711 fuel pump with a Barry Grant mech bypass however C&S now makes a real good mech bypass that I would use.

we got a gaerte carb last year and you send them your engine specs,what track size, etc and they completely set you one up or rebuild yours. it comes back a little rich so y ou have to down jet a few numbers but its flowed and everything. Sounds like your not wanting to buy a new one, i wasnt either but the results were worth it. they said its like adding 40 HP. It was very smooth as well. hope this helps some.

I spend my carb out to rebuild every winter.But the carb was on a 408 last year. This year we run a stock 350 bottom end to prove a point, so that some of other guys will step up and run mods this year. they all think you have to run big motors to compete. This year were going to run a 383 and a 421. I was looking for how jet it for the diffent motors.
