I was just wondering what the difference is between a camaro/trans-am ls1 the a corvette ls1? Why is the corvette rated at 25 more hp. Ive heard that the heads are a little bigger, but i want to know the true difference. Do the trans-am/camaro come with a manifold or a headers like the corvette?

I always wondered this as well.

Same engine. Intake and exhaust are the difference.

Plus some other minor differences such as the throttle body. I believe the actual opening size of the throttle body is the same, but the F-body has a different actuator mechanism. Peformance-wise, I don't really think there's any difference between the two.

Yes i already know about the whole camaro/trans-am being under-rated
thing, i just wanted to know the differnce. What actually about the exhaust and intake are different. I think the stock intake and TB for the camaro are 75mm? And the corvette is 78mm? Not sure though

funny u say, but when u modd them the same, LS1 Camaro dynos 10-15 rwhp more than the LS1 Vette (due to drivetrain loss of Hp in vette)

LS1 camaros put down more RWHP due to solid rear suspension as opposed to the C5s indenpendent suspensions. Camaros/TA are built for drag racing. They are a whole lot of fun!!!

my 99 camaro dynoed at 273rwhp stock that was an auto and my 99 vette did 317 stock but its a manual. both had 815 heads and the ls1 intake. you cant ask for a better comparison same year same engine but one is stick and one is auto so you be the judge

My 99 Formula was faster than my 00 C5. They put out the same or more power no question about it.

Corvette got a less restrictive air intake and exhaust system. Other than that, same motor.

corvette also has drive by wire as the f-body is still a cable assist system.

My 99 auto TA wount touch my 04 vette. The vette is a M6 and my wife was driving that and I was in the TA and she pulled hard in every gear. I drive the TA most of the time so I will never hear the end of it. haha

edit: forgot to consider the HP boost the LS1 got in 2002. That is probably why the vette is so much quicker than the TA. I did some research and the same year fbody has damn near the same 1/4 mile time as the vette.....just a slightly slower trap speed.
