Anyone running a carb motor with this blower, i need some help and have a few questions about this setup thats been sitting in my garage for nearly 1 year now.

1. What size carb will i need? i have a 650 DP jetted up 5 sizes. i think i need more fuel than that. the motor is a 350, has 2.02 1.6 valves, .509 280 lunati cam, nothing big, but only thing stock in the motor is the crank (and its magnaflexed and all the little junk)

2. What kind of exhaust can i run, i currently have Long tube headers and im not sure what i should run, should i jsut get a custom exhaust built??

3. any suggestions on how to make it run good.

4. When i run the motor at half throttle it perfroms well, but under full acceleration the motor just falls on its face, and doesnt move, basically dies, but literally doesnt.

 

I have a 142 on a ZZ4 in a 72chevelle with a 600 holley. You should be alright with that carb as far as running goes.Id say a 750 for max power as Ill be moving up shortly. Sounds like a problem in the secondaries like theyre opening but the fuel isnt getting there. Did you play with the timing at all? The freer flowing the exhaust the better; I have 3inch duals. Look at vaccuum hoses and **** like that around the advance and secondaries.

You know what, today i think im going to go and buy my *** a holley 750 with vaccum secondaires just for the hell of it, im tired of jacking with this car, im in a pissed off mood so im going to go blow money, now everyone pray that this does the trick!!

Well as far as free flow exhaust, would u call Open headers free enough!!

Well, im about to go buy it and slap it on, thanks for the inspiration!!
