My car is a 99 TA with a 383 stroker, ported 241s' ms3 cam, 102/102 intake, ud pulley, lid, 1 3/4 lts, x pipe ran out the back. It has a th350, 3000 stall, 12 bolt with 3.73 gears on a 28 inch tire. The car made 432 hp on motor and 548 on a very conservative nitrous tune by lane at hinsons. The only things I am changing is taking them 241s off which makes my car have a 10.3.1 cr and putting on a set of tfs 225s with roller rockers and getting my cr to about 11.1 What do you guys think the car will make on the Dyno with the head and rocker arm change????

I was just wondering what to expect. I did want to get my hopes too high and be disappointed on the Dyno. And I thought some of you might have some experience with a similar setup
