Thread: different size carbs?

Actually, you can still buy them. Depending on the company, you can get them better than new. Of course, thats the standard on GM products.

Have 2 Chevy 350s. Both are basiclly the same, head and cam wise. Both have Edelbrocks (Carter) , one is a 600 and the other a 500. You can really tell the difference performance wise.

About the total timing, how do you check that with a timing light??? if that is possible to do it that way. 32-36° is what I hear people say you want, but I don't know how to check it........

My 350 SBC is set to a total of 36° and I think that’s probably good for most SBC’s. First, you'll have to mark 36° on your harmonic balancer. An easy way to do this is to measure the circumference of your balancer and divide the measurement by 10 (360° ÷ 10 = 36°). Measure that calculated distance clockwise from the 0° mark and make a 36° timing mark on the harmonic balancer. If you want a different setting, just do the math.

Disconnect your vacuum advance. Connect your timing light, and run your engine up to about 3,000 RPM (for only a moment while you check the timing). Loosen and rotate the “dizzy” to make any adjustments you need.

Timing 101.

DRG I dont by into the CIX2 theory either, if that were the case my near stock 454 would need over 900 CFM. John

My panel truck 331 SB 650 Holley ran very strong. Went to big block with 750 Holley with mechanical secondaries. 389 GTO 650 Holley. Actually if I remeber right I took the carb. off the GTO when I sold it and used it on the 331 chevy. I always had good luck with the Holley. easy to tune. Little cold blooded maybe.
