I hoping to do a cam next.

Ment to say i took my l99 out, cause the timing chain tensioner broke after a cam swap. Dont make the same mistake as me and kiss pistons, replace it with dog bone tensioner when u do ur cam, only a 20 dallor part

If you are going to do a cam on your L99, take a look at the GPI Cam kits with vvt. They have everything you need. I would also do the trunion upgrade and oil pump upgrade at the same time. I am about to do this in the next couple months. 6l80 reduces power about 17% from what I have seen.

On the same dyno with the new setup it made 640. Does this sound right? Do u lose that much thru an auto? Any comments welcome! Thanks

That seems to be pretty darn close...maybe a little low. When estimating RWHP based off of crank HP, I typically go with 12% DL-loss on a manual and 22% on an auto. Others may feel differently.

Does GPI use the traditional Stage 1, 2, 3, etc...?

I’m thinking Stage 2 for a weekend toy and occasional road trips?
