I have a 350 bored .030 over, edelbrock performer intake, comp cam with a .49 lift, msd 6al ignition with a 55,000 volt coil. My uncle just gave me a edelbrock thunderseries 750 carb, i have a 650 on my car, i dont know wether to keep or to switch. Too much Carb or no?

Trench, how much RPM does the 350 see ?

keep in mind trenchdog73 "leaner is meaner".

my limiter is set at 6.5 but I usually dont take it above 5.5 if im not at the track.

As Denny W. noted the 750 will give you more top end power.However I think you will also see a decrease in throttle responce with the bigger carb.Also with the 750 you you will be dealing with mechanical secondaries witch also has an effect on street drivabilities.I would give it a shot anyways,You might like it.

If you take it to 6500 than Id say you could use a little more than what you have, personally Id use a 670 Holley Street Avenger. You could also install a 1" open spacer under the carb to increase plenum volume , has simialer effect to installing a slightly larger carb(doesnt always work that way though ). personally I think 750 is a bit much.
