    From a Dig, I'm sure he would pull maybe 2 cars on you, if he sticks it, and then it will stay like that most of the way. I ran up against a buddy of mines C5 Z06 and that was about what it was. Though he is producing more hp than me. I thought it was weird that I stayed that close to him.

    that kind of stuff is anybodys race... theoretically the vette should be faster, maybe not much at all.. but somewhat... but with even a slightly better driver the t/a can win... take me for ex... im bad at launching so i can get beat by a car i should never lose to stat wise, but yeah you get the point... driver error can make a wayyyy bigger diff than most people think

    LS1s in Vettes are throttle-by-wire, LS1s in f-bods use cables.

    Hot Rod took a new '98 WS6 (320HP) and a new '98 Vette (350HP), both M6s bone stock and tested them back to back on a dyno. The WS6 actually dyno'd higher. Whatever the vette might gain w/ that "better flowing exhaust" is given up w/ the IRS.

    Keep in mind too that the LS1 in the F-bodies was underrated.

    the vettes do have that true dual system though, compared to the f-bodys ypiped single. you'de think it would make more horsepower since it'll flow better. assuming they do make the same amount of power through the crank.

    He must have been the worst driver ever. I have more done to my car and the 05 Vette I drove would kill my car in any race. The LS2 has 50HP more and a few hundred pounds less weight. I guess lots of people get vettes and don't know how to drive them well

    back at ya. OP asked what differences there were, not which dynoed higher.

    Exactly, the title of the thread is "engine difference between WS6 and vette", to which the answer is NOTHING other than the TB (wire/cable), I have my doubts about the supposed cam diffs '98-'00 myself. But he certainly didn't ask about the exhaust either. I mentioned the dyno tests as proof that even with that non-engine difference it isn't enough to show up and help at the rear wheels.

    Agreed, although the OP's question wasn't real specific. He simply stated engine difference, which is open to interpretation, and someone had already expanded the topic by mentioning weight. Arguably, the TB could be considered not part of the engine either.

    The cams did change, 99 had the most agressive cam, 98 had the worst flowing heads. 01 and 02 have the ls6 intake manifold but the smallest cam which is why they have only about 5 more hp than the 98-00.

    That makes me want a bigger cam.

    The differences in stock ls1 cams is very minor, aroudn 5hp or so, not even a noticable difference.

    would it make a noticible HP difference if us 01-02 guys put a 99 cam in our cars?

    As I stated earlier in this thread `98-00 F-body cams are all the same.
    Whether the `98 heads are substandard to other's is purely speculation based on the casting process differences. Even if they did flow less it wouldn't be enough to notice a difference.

    Yes the difference would be noticeable but not worth the expense of the cam swap. So if you were going to do it go with an aftermarket Cam.

    It would be like 10hp at the crank at the most, not worth the work it wouldnt even shave .1 off the 1/4mile time, maybe .1 if your lucky.

    there's no way I'd go any where near a stock spec cam if I was going to swap them.
