which intake and carb
 

this is what my combo is going to be a 306 bottom end edelbrock heads full exuast a comp cams cam not sure of which one yet still waiting to get the intake and carb and a set of 373 gears my two choices for intakes where the weiland stealth and the edelbrock air gap what one do you think i would benefit more from and the carb im not sure if i should go with a 650 or 750 im definatly going to be using either the speed demon or the mighty demon just not sure what cfm.

I'd use an RPM and a 650, but that's just me.

Take care,

i have the rpm with a 650 on a 306 with gt40 heads in my 67fb and it runs great. i think it might be a little over carb'd though.

Rpm and 650 is a good setup.

Definitely
 

do not get hung up on the latest wonder product craze,go with the Holley 650 and the Eddy Air Gap.

If you ever notice in any of those magazine test,they always test a Demon without a choke horn on it and the Holley has a choke horn it.

If having a choke horn does not matter to you,get a Holley 650HP series carb and the Eddy Air Gap,just my opinion and 2 cents.

well, i think you need to think of the total combination not just a couple of pieces. if you run either intake or carb and put in a cam that has specs that dont coincide with the others then you are wasting you time. so build your motor around the power band you want to run in (ex. 1500-600 rpm, or 3000-7500 or idle -5500 rpm),decide what cam will then put you in the power band you want to live in and then the intake and heads and carb to match. here is my 2 cents worth, and if some gives me a penny for my thoughts, then someone is making a penny.

good points tarmon.





p.s. I had nothing but problems with my Holley carb, switched to an edelbrock, and it runs 100% better (x'cept for the current cooling problem)..

well IMOFHO,

holley's make more power

Holley's ROCK! The trick is understanding them. I can, and probably do, build them in my sleep, but it hasn't always been that way. Before I understood them, I thought they were junk because every time I took one apart, it didn't run right after I put it back together. Now, I have no doubt that they are the best overall carb on the market.


If they ever could have given the Predator a better idle circuit, it would have been the best, but they haven't, so go with a Holley.
