Thanks for all the replies guys. I'll keep everyone posted on how it goes. Just in the planning stages now. I gave my 89 Nighthawk to my son, so I decided to build a Monte Carlo SS to replace it.
I put up a photo album of the NIGHTHAWK if y'all are interested in it. Have raced it against a 2010 Camaro SS and a Shelby GT500 and killed them both! I designed the engine using Dyno Sim racing software, the actual engine was almost exactly HP and TQ as predicted. Getting ready to upgrade the transmission and torque converter and while out put on E-Tec 200 heads with ceramic coating, thin head gasket to bump up CR to 10.55:1 and a Stealth Ram intake, may switch out Crane gold 1.5:1 rockers to 1.6:1, haven't decided. That is supposed to bump us to 478 HP with 498 TQ.
The SS will have a 500-600 hp Texas Speed motor in it. TCI Super Streetfighter transmission, Vigilante torque converter, Moser 12 bolt, Baer brakes, lowering kit (nose down by about 1 inch). Haven't decided on rims yet. Have to look at subframe connecters. Spohn suspension and urethane bushings.
Any suggestions appreciated, especially for external mods, I want my car to look like no other SS, like the Nighthawk is unique.
