Default FunFest Engine Trivia Question

Sorry guys did not know where else to start this thread............

At the FunFest, there was a magazine sponsoring a Corvette engine trivia contest. The question was " Name 6 of 7 highest HP output RPO engines offered for Corvette".

Of course i developed a brain cramp and could only think of 4. Now that I have had some time to think about it, this is what I came up with:

'65 L78 396 / 425
'66 L72 427 / 425
'67 L71 427 / 435
'67 L88 427 / 430
'71 LS6 454 / 425
'06 LS7 427 / 505

I really don't know if these are the correct answers. They are my thoughts to the question. Do any of the experts out there have the real answer? I won't be able to sleep without knowing.

Thanks.

I thought the engines you listed were measured in gross hp ( horsepower measured without engine accessories and exhaust) , whereas today we measure in net hp (which includes those items). So, you really cant compare a 425hp big block with a 350hp ls1, right? I thought that the LS7, LS6, LS2, and LS1 engines were all more powerful than the big blocks of the 60s and 70s? Maybe someone can clarify.

How about the ZR1 Double O/H Cam engine with 405HP?

There were 2 ZL1 Vettes built in '69 with all aluminum blocks and heads. I don't know if 'actual' HP was ever determined, but I believe that I've rerad that some believe it to be close to 600 hp. Anyone have specifics on the ZL1s? Zuti

Thus the difficulty of the question.

I believe the contest rules stated advertised HP. So, I assumed that regardless of measurement standards it was the advertised HP of that particular era.

As for the ZL1, I don't know if that was a RPO edition.

I'm more confused than earlier. Thanks for the replys.

How about the early 66 427 that was released at 450HP and then rated down to 425HP because of insurance?

I filled it out, but the way it was worded was somewhat tricky.

It specifically said "advertised" hp. The reason I figure they did so, is 1, the L88 was only advertised at 430hp. The ZL1 was just a block option for the L88, it wasn't it's own engine desgnation.

Also, in 1970, there was an advertised option for the 460hp LS7, although no known cars were produced with it. The LS6 -425hp didn't appear until 1971.

They wanted 6 of the 7 highest adertised hp engines (hp in the year that engine was introduced), their RPO number, and the years that engine was offered.

If you look at the list above, 405hp doesn't quite make the cut.

If the 06 LS7 were rated the same as the older engines it would be pushing 600 hp.
