I bought these heads from a friend, but he had sent them to a guy named Jeff down in Harlingen, TX. He has a very good reputation on these LS1 set-ups. They are P/P with 2.00 and 1.57 Manley swirl posished valves with a back cut and a .045 mill with 7.35 push-rods.

For some reason the PI has been pretty tight. If you over stall it it will spin so it's more of a 2000 stall then flash. The PI feels good on the street, but if you want killer 60ft at the track and you want a PI you would need a 4200 or 4400 on a N/A set-up. I had a loose stall before advertized at 3800 and man my 60ft would average 1.65. I had a good feeling about this converter on Nitrous because I've noticed a tighter (3400 - 3600) TC will yield better ETs and MPH. Sort of like in FI set-ups.

I'm averaging about a 1.74 right now on the 4k. You can probably call PI and explain to them that you want a loose stall for a N/A set-up. This is the second re-stall and it is still tight. However I have a friend with a 4400 PI and he gets killer 60ft on 6.0. something in the 1.5x. With those stalls the TC may become inefficient on the top end so you may have to lock it at around 85MPH depending on gears.

I don't know the STR and it's a 10.5 not a 9.5 if I'm correct. If I would do it again I would get the 9.5.

You have one what? Go back to second grade with those sentence fragments. Are you telling me or asking me that you have one? If your are going to ask a question just ask it right and don't try to instigate something.
There was weight reduction with the removal of the passenger seat, the center console, the spare and that's all I can think of right now. I don't know the race weight. Once I weigh it I'll let you know.
