Just wanting to know if you guys knew of any differences in the intake manifold and injectors from a work truck 6.0 (I think LQ4) and my stock 5.3.
Also what did everyone agree on the flex fuel injector size? I believe last I heard was somewhere around 80 lbs.

Which company should I buy stage II heads from?

What year 5.3?? 99 5.3's had 19 lb/hr injectors if my memory serves me correctly. 2000 up had 24.7 lb/hr injectors. Intake should be the same.

Do think my engine likes antifreeze cause it is pinging its *** off. I thought you'd be able to answer every one of my questions.

I'm really looking forward to meeting up with you guys in Memphis alot this year. I'm going to check out the money races in Choctaw this weekend, and if the competition is steady and even, I'll have to get you guys to start coming down for a little profit.

Choctaw? Is that east, west, south, or I'm hoping north of Greenville? Would it be less than 2 hour drive from Memphis?
