That's a great time man. I expected a little better MPH increase but oh well, still nice gains.

Next up is the Underdrive Pulley then heads im thinking the Patriot Stg.2 LS6's and put 2.04/1.60 valves in correct seats milled to 61cc on .040 gasket or should i go 59cc on .040 gasket. then 1.85 rockers (hey every little bit helps). with 1.85 rockers and heads milled to 59cc on .040 gaskets would i have a problem with PTV? cam right now is a .588 lift

Skip the 1.85s IMO. If you really want to change your lift and such get a custom cam for your combo.

i really dont want to deal with another cam swap and with the better roller tip rockers it would help with stability and valvetrain weight...imo

full cam specs will help figure out your scr and dcr. lobe design too if its a comp cam. on a 64cc chamber my compression is at 11.0:1 so a 59cc head would have me runnin race gas on my setup.

You said heads were next as well, a cam swap isn't really more involved than a head swap. But to each is own, just figured I'd offer my 2 pennies.

BTW, I've heard some good things about that 228R cam anyway

Thats a great cam...basically the same as mine but a hair more agressive. i wish i went with that cam now. i would say that 59cc is too much for that combo. i can check it out later tonight. im ready to leave work now!

nice et, there is no doubt that ls6 intake works well. i helped a buddy swap one onto his car and he got .2 new best on the gtech.

you said you left your gate on but down. people have said for years that you see less wind resistance with the gate up. i always ran it up or took it off. i think down is the worst but never did any tests to prove it.
