OK, I almost have the LS1 in my truck ready to go. First off, let me explain what I have. 68 Chevy C10. LS1 basically stock, but with a COMP 236/242 .581/.581 110+2 cam, dual springs, shorter pushrods, LS2 timing chain, 700R4 trans with 2800 stall, 4.10 gears. Truck weighs approx. 3500lbs. This will mainly be a driver/cruiser with occasional autocross duty, and little to no drag racing or trips to Mexico street racing.

I've determined that I need somewhere around a 750cfm carb, but not sure which carb I should get. For the past several years I've had a 570 Street Avenger on my old 350, so I do like the Street Avenger series, but not sure that I will get full advantage of the 770 SA with vacuum secondaries. I know where I can get a good deal on a 750 Street HP, another friend of mine has a 750 DP, but I really like the hard core gray 750 Ultra HP. I just can't justify a $700 carb right now.

So here's my options. Which would you get and why?

-Holley 750 DP Price $150 (used)
-Holley 770 Street Avenger Price ~$400 (new)
-Holley 750 Street HP Price $400 (barely used) ~$500 (new)
-Holley 750 Ultra HP Price ~$720(new)

I would go for the street hp no question. But, if strapped for cash, the old 4779 Holley DP is tried and true.

Street HP would be great.

Thanks for the advice, guys. I finally bought the used 750 Street HP. I should be getting it in by the end of the week. I'll post pics when it gets here.
