new to ls1's with some questions
 

im building my 1st chevy (just got rid of my 88 mustang gt with a 4.6 dohc motor) car and i have decided to run nitrous. im running a complete 99 camaro drivetrain with a m6 tranny in a 68 camaro and i will be running a carbed ls1 system.
what size carb would you guys recommend? the motor is stock right now, but it will be fully built.
i was wondering if any one is running 9's with a t56?
what size fuels pumps are you guys running with big shot system?
and would multiple fuels pumps be necessary?
which block would you guys recommend i build on for my app lsx block or ls7? car will be driven close to everyday & i will be running a big shot (450 shot max) on a weekend or two but a 200-250 mostly
thanks in advance guys
