Default Carburation

I have a 383, stock heads (w/leaking valve seals), Comp Cams 12-211-2, Holley 4150 (PN 0-80145), Hedman headers, MSD 6A and 4 speed with 3.36 rear gear.

My plan is to install a Keisler TKO-500 next year. My fleeting plans have included new heads (what kind ????) and fuel injection. Lately I have been reading about Lars and many others concerning the original quadrajet and it's good points.

I've read many times the manufacturer Rebuilt Qjets are not that good. So I guess that I would need to find an OEM quadrajet and rebuild it or have a professional do it.

My 1973 started out an L-48 before I bought it. How do I determine what quadrajet to buy since my motor is not stock any more? I live in the San Antonio, TX area so I'm sure there are several business establishments that could take care of my needs. I just want to have some knowledge before I go there.

Any suggestions?

If you still have the stock Q-Jet, it can be easily tuned to support a performance motor. Lars is the man for advice on that.

Do you have the original carburetor? What is the compression ratio of the engine? What are the camshaft specs?

If you dont have a q-jet to rebuild, I have a new (less than 1 hour run time) JET Performance Stage 2 Q-jet. I bought it new this year to use on mildly built 350, but have since sold engine and bought new ZZ4 w/ recommended Speed Demon 650 mechanical sec. carb. The Q-jet cost me $360. If your interested, send me a PM. I'll give you a great deal on it, as I dont need it, and like I said its like brand new. I could use cash towards a new clutch thou.
