IHRA HP rating for 1998 LT1

[KRatcliff]

I don't race the IHRA enough to know this, so I will ask here. What is the HP rating on a 1998 Firebird LT1? I thought it was 325 hp, but that seems too low in my mind.

It's 325.

Thanks! It has me drooling to run B/FIA.

I never quite understood, or took the time to understand, how a 98 Camaro / Firebird can run an LT1 in "Stock". Maybe this is a good time to learn.

It is the only V8 that Pontiac submitted for 1998. No performance advantage at all. In fact, it is probably a mistake for me to run one instead of claiming a 1999 - 2002 and running a LS1.

But I am fond of the LT1 and it is cheaper so I don't mind being a little slower than the others.

Makes me wonder how one would be any slower it it were called a 1997.

Because it is a paper car none were built only on paper, GM did not have enough budget to give out LS1's and they wanted to win Manufacture Cup. You all complain about the Ford paper cars but Ford just copied what GM did! You have heard the term Monkey see Monkey do?

And now I know the rest of the story. Referencing NHRA's 1997 engine blueprint specs for Chevrolet, based on bore / stroke numbers, it appears the only thing cited is LT1.

If that is the case, would it be safe to say that since 1997 was the first year for the C5 Corvette that a guy could claim a C5 as a 1997 LT1, even though every 97 Corvette produced came with an LS1?

98 Chevrolet engine blueprint specs have LT1 numbers listed too. Does this mean any 98 Camaro, Corvette, Firebird can run LT1?. Based on what I am reading, the first year LS1 bore/ stroke / rod length numbers show up for Chevrolet or Pontiac is 1999.

The 1998 F-Bodies are all listed as LT1's.

The Corvette was not submitted from 97-99. The first year for an LS1 Corvette in the guide is 2000. So you can't claim a 97-99 Corvette at all.
