    Believe it or not I was a Mustang guy before I was an F-Body guy - about 8 years ago. I purchased a '95 Rio Red Cobra. It totally dissapointed me when I wen't to the track and ran low 15's in the low 90's. Didn't really know the car only made 245 horsepower until after I bought it

    '91 turbo fox, '97 vette

    Funny, I had a C5 vette demand to see my '92 5.0's bottle when I had a nice mild H/C/I combo on it and smoked him by more than a full second. It was great, he'd been talking all night about my car because I told him that I thought it would go quicker than his vette. My first runs were in the 13s, and after seeing me run badly, he decided to line up with me. I'd finally gotten the tune straight, and ended up running a 12.0@112 mph to his low 13 something. I can understand why he expected that I was spraying.

    I found out later that my engine was starving for fuel at the normal 40 psi, and needed 55 psi to bring the AFR down into the right range. That night I had also worked my way up from 10* timing up to 18* where it ran perfectly. Later on a dyno it made 253 rwhp at 10* timing and 40psi of fuel pressure lean-popping through the intake. With 55psi and 18* timing it made 311 rwhp SAE on a dynojet without ever leaving the dyno between the runs.

    Just a lesson for all you guys, you never know what to expect from those 5.0s. Anything could be lurking under the hoods: bolt-on 5.0s, H/C/I stroker Windsors, turbos, blowers, nitrous, hell you even find an LS1 every now and then. My car only weighed 2960 lbs without me in it, and it still had a full interior and had not be significantly lightened (spare tire, jack, differential dampner, and a couple other minor things.

    Just a fair warning to all of the LS1 guys out there that don't want to be embarrassed because you've seen how slow those old stock foxes are.

    BTW, don't flame me. I own a '97 vette, and love the LS1, too.

    Your average 5.0 is a joke. It was one of my first kills. However a built (dunno what he had done but it had at least a large cam the way it rattled my windows) 5.0 got me easily once by about three lengths to 80 mph.

    The 5.0 is my favorite engine, and the '87-'93 foxbody is still my favorite car in existence. So, I'm sorry to admit it, but yeah you're right. The average 5.0 that you roll up on in an LS1 is not really even a race. I don't really even consider racing them when I'm in the vette unless I can hear something going on under their hood.

    Still, I wouldn't talk shit to one of them that I saw at the track without something serious in my car.

    Shittin' on LS1's and LS2's ain't no "pretty built" 5.0. More like a really built 5.0. When you have a car that's so far behind, running 15's on average in stock trim, even getting into the 12's can be a pretty extensive task. I've raced 306 motored cars with mild heads/cam/ & intake when my LT1 sported nothing but cam & bolt-ons, and beat the crap out of them.

    You can make them fast, but it takes a lot!

    Yeah my friend has an 89 5.0 stang and has put a little over $10k into it. Supercharged and heaps of other goodies. He's pushing 600rwhp, too bad he can never get the thing to run...or else he can't traction and always breaks something. Now he needs a new rear end. They are fun to build and all but it's tough to maintain them when they have so much power and you can't get any traction. It becomes somewhat pointless after a certain point. Unless you have tons of money to work out the rear end and suspension as well...

    '91 turbo fox, '97 vette

    I was shittin' on LS1s with just a H/C/I package. It was an 11 second combo:

    AFR165 heads ($1300)
    FTI cam ($325)
    Ported Cobra intake (free + $250 for porting)
    Long Tube headers with matching H-pipe($300)
    Underdrive pullies ($80)
    24# injectors ($150)
    75mm MAF ($150-$200 don't remember)
    65mm TB ($150)
    255LPH fuel pump ($90)
    4.10 gears ($150)
    4 cyl springs (free)

    Races with stock LS1s wasn't even close. An LS6 Z06 would've been a decent race, but not from a stop. Eventually I blew up my stock tranny and put a Tremec TKO in its place. Could've kept running the stock tranny but wanted to be able to power shift, and I had plans for nitrous until the car was wrecked.

    It depends what you call "really built." I would consider that combo decent, but not really built. "Really built" to me means internal work like a stroker kit, or better internals. Then again, there wasn't much left to do on that combo except add some type of forced induction or go into the internals. Still, that's less than $3k in performance modifications, and that car flew. In fact, because it launched really well, it was quicker than my turbo car through the 1/4 from a stop - different story from a roll, of course.

    Just under 3 grand. And made an 11 sec car. Very nice, shows the 5.0s can be great drag cars. What numbers are you pushing?

    '91 turbo fox, '97 vette

    Before the long tubes and the port job to the cobra intake, it made 311 to the wheels as mentioned in the earlier post. Afterwards, I dunno....320 or so?

    The twin-turbo 5.0 on a stock shortblock (including cam), with GT40X heads, and a GT40 intake made 420 rwhp, which to me is less impressive than 320 n/a. Nothing really to write home about.

    My current single-turbo combo on a "really built" 331 stroker will push around 700 rwhp on 93 octane, and with the turbo maxed out will make over 1000 rwhp. If I change my tranny and throw in an auto, it probably will cost me about 100-150 rwhp. I think I've built a motor that can propel my street car (with a/c and a full interior) into the 8s.... it's all bench racing for now, though.
