Yep, today at lapeer dragway I turned a 13.55 @100 in a 305 tpi with headers and nitto drag radials (1.90 60 ft). Never touched an internal yet, but the blower will come this winter. Ill try and have a friend scan the timeslip this week.

Mid 13s is moving for an NA 305, especially when the motor is claimed to be untouched. What have you done to the intake, suspension, etc?

i dont see how a stock internal 305 could possibly run a 13.5,full ex.4.10s and sticky tires or perhaps a bottle!!

I'd like to know. If you tell me, I will be going after a junkyard tpi motor instead of my carbed 305.

With a 100mph trap speed I want to know whats up with that 305? What bolt-ons does it have?

If it was originally a manual car then it has the L98 cam in that 305, so thats good for a mid to high 14 right there. Slicks will probably drop another 3/10ths off that time at the least. With full bolt-ons, and a completely ported intake I can see a 100mph trap speed.

How close are you to sea level?

what year t56?

a couple years came with some pretty steep 1st gears, which could really be adventageous for launching that thing.

i say it's very possible.

there is a guy i use to read about adris shultz or something who managed mid 13s on a 305tpi and original 5spd.

Vid would be better than a slip.
My 88 Formula which was originally an Auto, now a T5 with 3.73 gears only gets a 92mph trap speed.

There is only 1 year with a steep 1st gear, that is a 93 since that year you could get either 2.73 or 3.28 rear gears with a T56. 94+ got 3.42 gears stock on all T56 cars.

after many years of experience with tpi cars,seen many things happen but i would really have to see this car run cause there is no way a (stock)305 is gonna run 13.n e thang without a ton of gear and full exhaust or nitrous,the mph is not there for nitrous so whats really goin on???????????????

Alright, let's see here. Since his car is G92, IF he had a 5 speed originally, then he did get the bigger cam and the 3.73 gears out back. If it was an auto, I believe they only got 3.42 or 3.23. Now he has to of had at least full exhuast, aftermarket runners, and a lot of intake mods to reach a speed of 100 in the 1/4. I highly doubt just swaping over to a t56 with drags will get that kind of result without some other things helping it out. So what's this car got done to it? Just remember guys, anything is possible, this is just hard to believe if he is stock with only the mods he has listed in his sig.

May be he had a very strong tailwind and was running down a very steep track or a very short one . So in my opinion NO WAY for a stock 305 TPI with that time.

That would be very impressive to run a 13.55 with a bone stock 305. I'd like to know how much the car weighed and what the DA was. I had a stock '85 TPI 305 in my Cutlass for a couple of years. It was the hyd flat tappet cam. It would run fairly consistent 14.9s bone stock in a 3650 lb car w/ driver and a 4L60E/3.23 gear. It ran a best of 14.88 just shy of 90mph. That was with a 1.90 sixty foot.

Clocks could have been off.

Cold air-cold fuel-good track-......I know he had two of these things at least but damn that`s hard to believe without seeing it! I gotta friend with a 92 5.7 with headers and free mods with BFG dr`s and his best at ubly is 13.90 with a 1.8 sixty...Oh yea 2500 stall w/ 3.42 and a A-4 What`s up with that little wheezer?
