Will flex fuel parts work on 2000 5.3?

[5.3olbessyZ71]

Thanks for the heads up on the pistons man. I will definately look into a set of forged pistons.

One more question. So the injectors and fuel rails are a direct drop in? Just need a tune to run them? or will it just run rich in the meantime?

I looked into the 90mm TB from Edelbrock. Looks like a good product, are there any other manufactuerers you would recommend for a 90mm cable TB?

Also, what is the size of the stock 2000 5.3 throttle body?
