Default Anyone have any idea ??

I had an 01 Mustang Bullitt quite a few mods... decide to trade it on craiglist, so anyways i came across this 97 Trans am and traded... its in the shop gettin transmition work done to it.. havent really got to drive it much. so i was just wondering if anyone had anything comparable to this that could tell me how it runs for a daily driver or for a drag car.. i was told this car pushes out just over 600 hp..

heres the list of mods..

Lt4
Bottom End Rebuild: The crank
was turned .010 on the
mains, and .020 on the rods. The machine work was
done by Midwest Machine in Tulsa. The rods were also
resized to match the crank. Clevite 77 rod bearings,
and Federal Mogul main bearings were used. New rings
were installed also at this time.

Top End Rebuild: the heads were milled and mildly
ported by Kessler Engines in Bartlesville. They were
milled .030, and new valve guides/seats/etc. were
installed. A complete valve job was done.
Felpro
gaskets were used all around. The intake was also
gasket matched, polished and painted.

Trans was rebuilt quite a bit stronger than stock. Corvette sirvios, gears, clutches and 3500 stall converter



Valvetrain:
Cam kit bought from Combination Motorsports
(www.cmotorsports.com).
Comp Cams XE 224/230 .536/.544 w/1.6 RR's 112 LSA
EX Components Hardened pushrods
EX Components Titanium 7 degree locks
EX components single springs good to .600 lift

In addition to the kit, I bought:

Dude!... We're all F-Body people so we'll always welcome a new person into the fold but I think someone "took you for a ride"!... 400ish HP is my best round about number! I wouldn't say 600!!! Also, as long as you had it in great shape, car for car, I would have held onto the Bullit!

trading a basicly stock mustang for a Trans am with motor work done and i got ripped? bluebook wise maybe i did... car for car i didnt... this motor has 5,000 miles... mustang had 120,000.. needed a new clutch and synchros in the tranny the trans am has vette rims and tired on it.. looks damn good to me... it was worth taking a little loss to have the t-tops and added power i think..... maybe i'm a fool... im sure it dont have 600 hp... just what the old man was sayin...

Should have gone with a LS1 T/A that's where all the aftermarket is at
But either way welcome to ls1tech, the 97 T/A is still a bad *** car. With what you have listed, i would say more less around 430rwhp n/a

i honestly think you couldve easily gotten a ls1 car for you bullitt, and an unmolested one at that (with these cars and shady people, sometimes stock is better!)

I also think 420whp is over estimating it, ive been wrong befor, i hope i am.

it wasnt a dark red trans am was it? I learned my lesson, traded my 2000 gsxr 750 for the dark red 94 i have now. Some people have NO CLUE about working on a car. Mine almost burned down!

lesson in life #872 - stay away from dark red trans am's on craigslist

well at least you have a better car now.those 2v 4.6s dont go worth crap without boost.your new car will kick the crap out of your old one.

and I think lt1s are just as good as ls1s,and run as good too.
