Disagreement respectfully noted

Ok. If it's in print and GM released the info is should be a simple task for you to post some facts to support your disagreement or at least direct me to some location on the web where I can read those facts.

1995 Firehawk, LT1 rated at 315 sae net hp.

1994 Chevrolet Power-The Official Factory Performance Guide" 1994 General Motors Corporation Page 10

There is an actual reference to an actual gross number for the GEN II LT1, but I cant locate it at this time.

the small, hard bound, "drivers book" that came in the owners kit.

Don't quote me on this, but I read in an old Legend magazine about the development of the LT5, and believe it was stated they were seeing 445 SAE with open headers on the dyno.

The next gen ZR-1if it wasn't killed off would have been 450hp.

Actually, if that was in the old Legend magazine, whatever article that was must have been talking about the Record Run engine which, slightly modified, made 440-hp.

Also, no engine could make "445 SAE with open headers" because the SAE test standard mandates a full exhaust system.

Stock LT5s made 375-hp SAE net or 425-hp gross with open exhaust.

The so called "third generation LT5" which would have gone to production for 1995 had additional improvements, including variable valve timing, and would have been rated at 475-hp SAE net. The development program which was that engine ended when the ZR-1 was killed.
