600 CFM on a LS2?

Hey they,

I have a 2008 LS2 engine off a Trailblazer SS and I'm wondering if I can put a 600 CFM Edelbrock w/elect choke on it.

The holley DP that is on it is junk, and I'm looking for a quick and dirty carb for this, my local autoparts store has on one on the shelf (shocking!)

Is 600 CFM too small?

thanks!
Nick

The 600 Eddy, works fine on my stock 5.3....if you are street , I would say use it. More power/strip fun, I would go with a Quik fuel carb, in the 650- 750 cfm range. my bro has a DP 650, on a 383 S-10. The truck is a solid 12.5 ride ...out of the box, no tuning? Nice carb...Longhorn

Understand, that the edelbrock carb, likes no more than 5 psi on fuel psi Not a race carb...Quik fuel/Holley, would be my choice Let the rest of the boys play.....longhorn

What he^^^ said. I personally would skip the edelbrock because they can be a finnicky pain in the @ss. You will get better performance out of holley street avenger. Quick fuel or Pro form would be my choice. Vacuum secondaries in a heavy truck with a mild engine will yield the best results.

Re: 600 CFM on a LS2?

You know, I did some digging around and ended up with a Holley 670.

The carb on there now is a Holley, we'll find out tomorrow if I did the right thing.

I'm a Q-jet man at heart, but I'm old enough to know I should try new things...

If successful I'll post some burnout pics!

You made a good choice. That carb will work great for your application.
