You will be fine. The biggest thing to get our GTs moving is gears and weight reduction. Add 800+lbs and you are climbing a much steeper hill. Autos are good once you put have J-mod, stall, tune for higher shift points but still.

There is no such thing as a 351 svo in any of these ex cop cars. The largest a 281 can go safely is a 324. The SVO heads are like lt4 heads to you fbody guys. The are still 2v though. The SVO intake is the precursor to the Bullitt.

Instead of racing for money race for a bumper sticker. And go find the gayest one you can and place it there!
