how much hp can a 86 camaro take with t tops w/0 flexing. and then with sub frame connectors? i was thinking of puting a ls3 of 620 hp in the car.

 

Welcome to TGO. Even an LG4 (a puny 305) will put stress cracks behind the drip rails of a coupe, though I suspect that would be eliminated with SFC's.

Really has little to do with power like mentioned - it's simple driving. Entering a driveway at an angle so your air dam doesn't scrape flexes that car alot. Engine power has very little to do with it - until you get into stickies and clutch dumps, 1000 hp motor won't flx the car anymore than 150 hp.

 

put the subframes on anyway. GM didnt stick the 350tpi behind a Ttop car for a reason. I had cracks in the corners of my doors in my stock formula 350.

 

Hardtops all cracked along the upper corners. Its just body flex, V6's got it just as bad

Also, 350 and T-tops were available, just not all years

SFC's are a good idea for any 3rd gen, V6, stock, super mods, whatever

 

I'd say that car would want quality subframes and a 6 point roll bar, with 620hp you're well into the 10 second range at the track and it would be a safety requirement regardless.

 

Didnt GM beef up the later years chassis inorder to accomodate the 350?

 

agreed, first time u hit the 11.99 sec barrier there not gona let you do anymore runs. A 6pt is required at 11.99s and 6pt means door bars, hoop and rear bars... trans tunnel bars are not included in a 6pt. And putting 6pt bars (hoop, trans tunnel and rear bars) is not legally a 6pt roll bar.

 

No.

I'm going to move this to chassis and suspension, since this isn't an engine swap topic.

 

No, T-top cars got the little snubbers in the door jambs but thats it. 92 cars got some extra adhesive to quiet rattles, but no chassis changes

 

11.49 or faster and 13.49 for convertibles.
