Yeah, thats about right. the G92 305 has good power and was on par with L98 back in the day but L98 has 230-245hp depending on year and 330-345lbft torque which goes along way in drag racing. Your car is quick but these L98's running low 14's can only hang with Lt1's for little while.
Lt1 has 275-285 hp depending if it is an SS or not. 6speed and 3.42's and your seeing 14 flats to high 13's. I have seen it many times before. Unless he launches bad and your launch is perfect, he will run you down.

ya you shouldnt of bet...
on the highway LT1 got great top end and will murder you up there since tpi doesnt have much of a top end power
off the line you could possibly get a 1/2 car or so off the line but he will just fly by you after that.
what are 305 tpi's like low 15s?

how are the gears to low, if u calculate it at red line w/ the car is doing about 160mph, 157 technically. I though i read some where that after about 120-130 Third gen camaro intakes act like a N/A supercharger, boost is created just from the amount of air flow?
ok
didnt u say
ps one thing u willl learn fast is the members here dont like bs i learned it now u ned to.
, - im seventeen, got a 89' Iroc TPI 305 G92, pushing about 400 horse at the fly. 36347.1 miles, far from a rusted body. ......Just for props- but I aint allowed to drive by myself

yeah your G92 305 with those gears is probly the quickest 305 car produced. Mid 14's is quite possible when driven good.
Lt1's are low low 14's to high 13's

i hit 130 no prob in my L98 with just catback at the time. 2.77 gears and lots more left. 145-150 would have been possible.
My friend owns a 00 WS6 ans he only hit 160.

my mommy gave me my keys back just not my license plate. lol
and the motor was rebuilt stock, the race is w/ Fast_LT1_Z28.
I dont know how he drives but i need to start practicing lauching, he wants to run the quater mile. I dont want to run funny juice in my car, im figuring, headers, w/ cutaways then dual cats 3" piping and dual racing mufflers. "true dual" not the fing stock setup.
Everything really works fine except i need an alternator.
would it be good move to get a turbo setup when i do the headers. wastegates, boost controllers and a better intake.

Uhhh... Hell yeah a turbo would be a good idea. it is tricky to do and can be expensive. I would stick to full exhaust with cutouts and big headers/longtubes and open up that TPI base and mild cam to go with it. Then just add a supercharger kit and you will be fast.
Or how about gears. Get some 3.70's and a set of slicks/drag radials. Sell your 3.45's to me LOL
please

thanx for the back up and the exhaust really might help but i dont wanna dump more than $3,000
And unless u put in 4.11's, why do a gear change, theres no point in dropping 3.73's
You just want a cheap barely used rear end

Well, 3.70 could help you some over the 3.45's. 4.11's would be great too but not sure where to get those at for ninebolts
I got 2.77's now and 3.45's would be perfect for my car. LOL doing 3.27's in spring cuz i have them but 3.45's would run great for my setup now and what I plan on doing down the road. LOL

cool, well 3000 in the right places will make a good running car.
Consider doing some World S/R torquer 305 heads for more flow. Port them out some and add a Superram and cam to match. People say superram is too much for 305 but with heads and cam, it will be perfect. That alone should be good for 50hp+

well if you serius about doing this TT setup thies alot more then you would think to it. ALOT more. your gonna want to use a stonger piston. conecting rods. diffren't crank. diffren't head bolts mayb even heads. and diffrne't exaust. new vavle springs. and then the turbo's the costom piping for them. and the the headers for them.. it's gonna be a toatl 3k if you do it your self. but you'll be well over 500hp. a guy just did this in MN and it's pretty sweet. i'll post pics of his motor later. and some other dude in MN has a 8x trubo car. but just somthing to talk about... and you gonna get you but handed to you in the race
