600CFM Edelbrock carb
 

Would a 600CFM edelbrock carb be good enough to put on an 351 with a performer intake and full exhaust? Or am i cutting it to close?

Thats plenty. Theres 10 and 11 second NHRA stockers that run only a 600 cfm carb, A couple months ago one of the mustang mags run a carb test on their in house drag car with 351 (very built engine) and went quicker with 560 cfm Barry Grant carb over a 750

awesome. Thanks

Carter AFB versus Holleys
 

My thoughts are that the Carter AFB or Edelbrock air valve actuated secondary carbs need a higher rated CFM than the Holley or Demon vacuum diaphram actuated secondary carbs.

If it's a Holley or a Demon, I would use a 625 Road Demon. If you're set on an Edelbrock, I would use a 750 cfm carb.

Hmmm, mixed opinions. Anyone else have something to add?

i picked up .2 by switching from a brand new box stock 650 edelbrock to a new box stock 650 holly dp.

either carb is good but thats just my experience in one case.

im going for more of a streetable carb,, that is why i went with the edelbrock. But will the 600cfm carb cut it on my 351 engine?

right now i have all this stuff for my engine that has to still be installed.

4.030" pistons
performer intake
full exhaust - 3"
Mac stubbie headers
stock heads(rebuilt)
pullies
and im thinking maybe a custom cam from crane


will the 600 CFm carb be enough for this combo?

i've ran edelbrocks and hollys on the street ... both are good carbs..

and in your case i think the carb you mentioned would be enough for your motor. just make sure to tune it.

with a 600cfm carb on your engine, you'll have alot better vacuum signal to the carb, better throttle response and torque where you need it, and torque where the power-band is on your engine.
