Yeah, it wasn't until 1992 that the LT-1 replaced the L98. Here is the website I found that information at:
http://www.idavette.net/hib/c4hib.htm The dates are fuzzy, but the L98 started out with a hydraulic flat tappet cam and iron heads, and made 230 hp, but a BUNCH of torque. The mild cam and tuned port runners didn't allow much power above 4400 rpm, which is what limited the hp number.
Then the L98 got aluminum heads and higher compression, and went up to 240 hp, I think that was 1987.
Then the L98 got a hydraulic roller cam and was good for 250 hp. That stayed until 1992 when the new generation small block 350 with the LT-1 intake and reverse cooling configuration made its debut with 300 hp. It made less torque than the L98, but had much better top end power thanks to its new 6000 rpm redline.
It's a little trivia but it's interesting. If you can get ahold of that torquey L98 tuned port injection, it would be fantastic in a truck!!!
