just buy the 4.8/6speed. grab a 6.2 have the rod/main cap bolts swapped out to ARP, throw a spec'd cam into it, mill the heads if you want to stay N/A, put a 3200 converter and put it on DRs. you'll have 12.4-12.99 easy.

my CCSB has a 6.2/milled heads/cam/LTs/3200 converter/4:10s(it had 3:42s when i ran it) in 96* weather it went 13.0 @ 103.8mph. my truck is faster on my street tires from a roll, but can't do any kind of 25mph and below without it blowing the tires off of it.

Daryn C went 12.4x with his SCSB with a 6.2/milled heads/mild p&p heads/LTs/3600 converter/3:73s/dunno what size DR/Slick.

 

RPM is a place that has a lot of knowledge, my buddy works there. High end stuff rolls in and out of there.

Just spend the money for the 6.2 and be done, don't waste the time on looking for a 6.2 and what not. If you can afford it go for it.

I take that you are in the Claymont/Wilmington area?

 

I'm in newark off pleasant valley road between old baltimore pike and rt40. thats why I say RPM is about 20min away.

Can't get a regular cab 6.2 from the factory.

 

Then get the 5.3. Many people have the 4.8 and have done with it. I just come's down to personal preference. Either of the engine's are going to be awesome!

I skimmed over the whole thread and miss the 20 minutes away, I apologize.

 

I don't think you can get a V6 or even 4.8l with the new 6 speed auto. So unless you want a 4l60e you need to get a 5.3l.

 

ii have a rcsb 5.3/4 speed .. full bolt on and cam went 13.50 ... new times to come in the winter with the stall ..

 

your truck is a freak of nature

5.3/6l80e supercharged, or turboed will get you where you wanna be and be a hell of a roll racer.

 

Correct. You have to get the 5.3/6.2 to get the 6-speed. The v6 & 4.8 liter still get the 4L60E.

 

just get a 5.3/6l80e truck and get a specd cam and a blower...
