has anyone ever heard of an f-body frame getting bent from too much torque or ever had their own twisted from too much torque, and how much would it be to fix it?

 

Yes, I've heard of it. In fact it was one of GM's concerns when they were increasing the power for the cars. I beleive that in 1990 you could not get the 350 TPI with T-tops because GM was afraid that it would cause torsion issues. It was only for one year though.

Yeah, if you are gonna put some major power behind a third gen F-body then you should consider SFC's. I'd also look into a STB and a Wonderbar. Those 3 things should make a day and night difference in the car on just a stock motor.

As for the price, well it depends. But its always expensive to straighten a frame.

 

what are SFC's and STB and Wonderbar and how much do they run ya if u can give me a ball park figure? thanks

 

I think what he's talking about are SubFrame Connectors and Strut tower brace. Sorry I dont know much about them but maybe you try a search with those keywords and see what you get. That all the help I can provide

 

alright thanks alot i will do that...with out u tellin me that i was clueless!

 

im goin to bed for the night but if anyone replies could they please email me or just a post is fine if u dont wanna email me my address is in my profile thanks

 

You'll see info on SFC's, STB's and Wonderbars all around the place here.

Subframe connectors tie the front and rear of your car together. They increase the stiffness of the chassis. Which also helps with hard launches and they increase the torsional rigidity of the chassis.

A Strut Tower Brace ties the two front shock towers together, decreasing flex in the front end.

A Wonderbar does pretty much the same thing as the STB, but it mounts in a different place.

 

Actually 350's and t-tops were not availible from 91-92. And 350's and t5's were not availible any year unless it was a custom job.

 

All this argument about what years were available with what options is monkey-spank and a waste of time. The answer is much simpler.

Just drive into your driveway where one wheel is on the driveway, and the other 3 are still on the street; and open the driver's door.

Then answer the question: is your car stiff enough? Does it really matter how much or how little power it has, if you can't even drive it on a slightly uneven surface without racking it?

A frame shop can fix it in a matter of minutes. It could be considered part of sub-frame connector installation, since nearly all of these cars are a little tweaked to begin with.

 

or even put a jack under one side of ur car and try to open the door. i can barley get my drivers side door when that side it jack up.. especialy when its on a lift. SFC are the best suspension mod u can get period.

 

My last Z had a severely bent frame. to many hard launches with the laughing gas. What made it so bad was that it was 91z 350tpi WITH ttops. They where dealer installed. Stupid me never added frame connectors and the results where pretty bad.
