lol yay 19 sec 1/4 miles your the bomb diggity . lol im just playing atleast your responsible and going to a strip. but i cant remember if the 280 is a rwd or fwd. if its a rwd get a locking differential and it should drop your times close to a seccond. other than that just keep shaving weight, finding ways to hook up (launch, get traction) better. and add hp bit by bit and work on shifting and rts and just keep going at it. practice makes perfect. even if you dont mod it if you practice youll start shaving 1/10ths of secconds off

I think a limited slip differential would be better all around, but I guess if your diff can be locked and unlocked like a 4x4, and you are serious enough about just drag racing then go for it.

yea there are better choices than a straight locker. the tru trec system uses clutches to lock it under hard accelaration but still allows the outer wheel to turn faster in a turn. the only down side is that turning from a stop the inner wheel will chirp trying to catch up with the outer wheel. but other than that its a good all around system. i just said locker cause he was talking about 1/4 mile runs. but yea a limited slip of some sort would be the best if you still plan to street the car

You don't have to remember facts like that for muscle cars. They all send the power to the correct place (like all my favorite cars).

no i mean i remember more than if its fwd or rwd. but imports kinda just dont catch my attention that much regardless of if it has a v8 in it or if its rwd. ive just always been more fasinated (sp?) with muscle cars than i have with imports. but yea if your talking about sending the power to the correct place (as in rwd) then i deffinatly have to agree. fwd and awd is cool and all. but rwd is the drive train capable of doing wheelies down the track

don't even bother modding the stock motor. You'll never get the performance you want. Best bet is to find a good SR20DET. You can find a good Red top (220HP) for 2500 or so and a good Black top (240HP) for 3500 hundred. The swap is a 2 to 3 day process for a good shop.

i would hope he would be in the mid 14's with a red top....240's usually run in the mid to low 14's i've seen it quite a few times myself ...it might weigh a little more(not sure though) but it should be well capable of a 14 second pass....depending on driver(big factor)

The 280 weighs more than the 240, and has less hp. I believe the 240 is 2300lbs. and 150 horses, while the 280 is 2800lbs and 135 horses.

Engine, suspension, drivetrain.

With times like that, I would think changing from points to electronic might make a tangeable difference.

Wow, thats sad.

Well, lets start with getting some more air into that old girl. Start with an intake, then move to headers and an exhaust system.

Nopi
Im sure youll find almost all your needs there.
