    What are you smokin?? They are high 13 second cars stock. And 0-60 under 5 seconds. Virstually the same #s as a LS1 f-body. From a higher roll would be your best chance of winning.

    i wouldnt worry about it if i were u...the GN had 235 bhp and 330 lb-ft...and as u already kno it doesnt have as much whp...from what ive just looked up it seems they are fast as hell off the line but dont have a whole lot up top...i wouldnt worry about it if i were u. plus its a 3500+lb car...so id think ud have the advantage

    ur right 0-60 is 5 sec...but everything ive looked up says 1/4 in 15.8 unless its modded...now the 87 GNX runs the 1/4 in 13.43@ 103mph...but we are talkin about a 86 grand national...not the 87 turbo

    Performance: Grand National: 1/4 mile in 14.23 seconds @ 98 mph. GNX: 0-60 in 5.5 seconds, 1/4 mile in 13.43 seconds @ 103 mph.

    I've seen plenty of drivers push stock GN's well into the low 13's...and many slightly modded ones go low 12's-high 11's....a friend of mine had a slightly modded GNX....no way my WS6 could beat that thing....it was wicked quick! Even a stock 86-87 GN or GNX is going to give you a good run for your money...

    Here's a cool video of a pair of modded GN's racing a Viper...

    trust me its no 15 second car. There is no car that runs 0-60 in 5 seconds then runs a high 15second 1/4. And as far as the power #s. the cars were underrated quite a bit. GM won't ever let anything have a HP # higher than a 'vette in print.

    The Grand National will run the quarter mile about as fast as a first gen TT Stealth. I raced one with my TT Stealth when I first got it and we stayed within a bumper of each other. The Stealth was stock at the time so unless you are worried about a car capable of a 13.8 in the quarter mile, then I wouldn't worry too much. The real problem is if he is REALLY stock, those cars are stupid fast with a few hundred dollars in them. The GNX is few and far between, so I doubt that if anyone has one they would be willing to beat on their car for a race.

    86 then went intercooled... I dont know tons about them, but definetly 13s stock and factor in that the tire technology has come a long way.

    2000 trans am ws6

    well i have a 00 ws6, my pops has the 86 gn with a lil bit more beefed up turbo and we went to the track.. he was runnin drag radials and i was completely stock.. i beat him all 3 times, but he did manage to run a 13.2. he was just a lil slow off the line with turbo lag. but thats all good. if hes stock it would be a good race but ull most likely take him. especially since some of the 98 t/a's have better cams.

    I bet you could pull a 6.3 0-60
