I never had a trans problem, but I didn't thrash it either. Well, I was hard enough on it to break the transfer case once, but the trans was OK.

I just took it easy during daily driving and hit the track occasionally. Shift kit, servo, and yank 2800 gave me 1.6x 60 foot times.

If u go 4L80 ull be sacrificing rwhp...R/

You can't run a underdrive crank pulley with a Radix, it will slow down how fast your turning the blower

Not to sound like a newbie, but how do I find out what trans is in my truck? I bought it to tow with, not to race it. 2001 Silverado 2500 series 6.0l. I bought it brand new but have no clue where the window sticker is! Not a HD model either.

You should have a 4L80E.

Anyways, the reason it will be too late is because I've just spent about 3g's on stuff to stay NA...once I put the ported heads on compression will be well too high for FI. The heads/cam should put me at 400rwhp or so, but it seems the radix will yield more power for cheaper. It's not to late for me to jump ship and sell all this stuff I have in favor of the blower.

Thoughts?

what is your current CR?
