Welcome aboard thirdgen.org.

Personally, I don't understand the draw of a carb on an LS engine. I know there are a couple of members with very fast track-only cars with carb'd LS1's, but for the street, it just doesn't make a lick of sense to me.

Since you're talking about the Performer carb package, I assume you want this to be a street car. In that case, at least use an overdrive transmission (TH700R-4).

If you decide to stick with EFI, then go with a 4L60E transmission.

Thank you man


the carb is good for me because i like old school and the car not for daily used but for weekend


can i uesd th400 because is Stronger than th700R4 ?? for street racer

If your intent is to street race, I will not contribute further.

youre better off with injection. switching to carb is going to be more expensive than you think.

yeah i once checked the prices, for it turned out it was going to be almost a grand more expesive

Honestly, think of all the money you'll save with FI rather than going carb and fuel injection is the way to go these days, just my though.
