I got a 91 camaro z28, me and local shop are considering dropping a LT1 in it and twin turboing it at bout 15 psi *to start with*. What i'm wanting to know do i need to drop my 700R4 for a 46LE auto tranny. Do i need new motor mounts and what bout wiring everything up. Last but not least i can think of right now the Rear end what all do suggest going to a 12bolt or 9 bolt. The car will be steet/strip/show. But we want a nice sleep look so we don't plan on a high rise hood or nethign. Also bout intercooler placment what do u all suggest behind the radator or maybe 2 side mounts?
