Well, if they're pulling (mind you, I'm talking about the '01-'02s here) 315rwhp minimum with a %15 drive train loss, that is 370bhp.
315 minimum? Very very few put down 315 on the rollers in stock form, it would have to be a generous dyno. Im appreciate your opinion of my engine, though.
Not the 01-02 cars, average for these is 300-315 rwhp.

Very true.its been said too many times, and some readers still dont see through the misconception..ALL ls1s will dyno within 10 -15 hp of eachother in stock form.As far as the SS,WS6 and Firehawks go,these cars are just badge and small body details that give these cars a higher resale value.My point, for those who dont want to admit it.....Take a stock Z28[manual] and run it heads up with a SS[manual] with equal drivers.I firmly stand by the fact that since the guy in the SS payed thousands more, they will cross the line within tenths of eachother..its the badges and the spoiler and hood that makes these cars stand out ,not the fact that the guy who could afford the base model can go heads up all day long....

There where i few details missed that i have said on some other posts.
2001: The LS1's got a lightly smaller cam, and they got a slightly different head core. Heads changed from casting #853 to #241. Also the LS6 block came on 15% on the F-bodies.
2002: 25% of the F-bodies got the LS6 block.
There is essentially no power difference between models. Like said its just looks and handling changes. Some of the SLP cars did get some select extras worth more hp's though. Also it is not uncommon for a LS1 to put down 315rwhp in its stock form. It happens sometimes. The norm though for 01-02 is around 305-310. The 97(vette)-00 is around 300+/-. But there are the few that put down 315, probably LS6 blocks on most, because of the better oiling, im not sure. That point still hasnt been tested.

I guess you probably know more about it than I do; I never dynoed mine. My gal and I went to dyno our Camaros and I was gonna do one run stock, one with the lid, and one with the cutout open but it was broken when we got there. Now that I have longtubes and a catless Y-pipe I'll really never be able to do it stock, so I'll never know what it would have put down.

Not to leave the corvettes out,they are just lighter,with a better aero package and GM gets a little more hp out of the cam.
True about weight being the straight-line performance difference, but I believe the cam specs are identical.
What do u think the reason for the hp power difference is???[corvettes vs other ls1s]Not the cost,or the wieght,or the looks.....GM,as i said. tunes the engines for more power.This might include the internals of the engine and how it performs.Do u know what gives the ls1 gtos 350 hp???Just some questions to your reply tommyv8..Do u also know cams can be tuned for more or less power??

So as you can see there has been basically very small differences in cams. The 01-02 is basically the same.
To answer some of your question 32valve. The vettes dont make more hp. There are equal to the F-bodies and sometimes actually make less power, because the independant rear suspension robs some hps. The differences are actually just weight. F-bodies are only about .2 behind the vettes on the 1/4 with everything being equal(not including ZO6's).
The GTOs rated at 350hp where jsut actually given the proper rating. The F-bodies where underrated by about 30hp. They should have been rated at 350 also. The speculation is that the vette owners would get pissed and GM would lose some long time vette guys. Dont know what made them change there minds with rating the GTO correctly. Maybe they discovered it wouldnt matter.
Also i just wanted to let you guys know that LS1tech just opened up a new Forum site for the mustang. Here is a link to it, you should go and check it out.

The reason is very simple. Spend $50k on a 350hp Vette, or $25k on a new f-body with 350hp. That doesn't look very good. Hence the reason they're rated lower than the Vette. Mine put down 325rwhp with exhaust/drop-in k&n. It's the slowest year made and was dyno'd with the LS1 intake and heat soaked like a SOB.
Goes back and see this was already answered....DOH!
