ok so i just got a new 1990 trans am and it has 350hp crate, and there are stress cracks at the top of the door, so is that a paint stress crack or is the metal actually cracking from all the torque. if so wat can i do to prevent any more.

 

i doubt it is stress cracks from the body and tq more then likely it is just the paint cracking, if it had t-top which the way u worded it u don't then i could c it being stress crack but unlikey from what u said plus u would need way more power then a create motor comes with.

 

k thanks, ill just touch it up with some paint then, and no it does not have t tops.

 

Actually, where the roof meets the back of the door is one of the places to look to see if the cas has had a hard life. The 3rd gen cars were pretty flexible and a strong engine prodded by a heavy foot could really stress the bodywork. You need to ge a body shop to properly weld things toghether before painting and install subframe connectors and strut tower braces to stiffen things up.
