Hey everybody how you guys doing well and kind of new to the this web.
I putting together a Twin MP70 turbo LQ4 with some good rods and pistons,well from reading in this site and the LS site dicided to go with the 4L80E tranny.
Well the question is I got the tranny from a guy that just had it rebuild by GM as well the stock converter the tranny doesn't have no more than 600 miles on it,you guys think should I open it to put a shift kit or live it alone for now.
also how much horse powr are they rated in stock form,I was also thinking in runing the stock convr. for now ,well if I need to get a convr,I'll get it.
well I'm shooting for 600 to 800HP and I want the car to be good on the street [going to drive it alot on the street,weekend warrior].
Any advice an what should I do.........

Thanxxx.
