Corvette Small Block Power Chart
I just noticed an interesting graph at CorvetteBlogger.Com. It is a GM graph that shows advertised horsepower for all Corvette small-block engines. Wow, since 1996 output has really increased dramatically.
Be aware that the graph is clearly labelled "advertised horsepower". Comparing the pre-1972 output figures with the later ones is erroneous in regard to actually comparing "real" output. Remove ~80 horsepower from the pre-72 (SAE Gross) horsepower figures so that you can compare apples to apples.
Here is a link to the graph:

With the factory rated HP of 230 @ 4,800 rpm I always wondered what it would be at 5,800-6,800 rpm. These motors are certainly capable of more rpm than 4,800. The factory LT-5 is rated at 375hp at 5,800. I know it's cammed more and compression may be up, but it looks like they de-rated hp on L-98 by lowering rpm.

If you look right below the picture, you will see a link for a HI RES version, click on it and then click on the picture again, it will be big enough for you for sure. It does not fit on my 22" monitor.

There was nothing derated about an L98. It made what it made and it peaked early. Turning it above 5000 RPM without modifying the induction system is a waste of time.

It's still just a photograph of a slide. Anyone have the original slide? Would be cool to print out and hang up.
