Since you have it apart, you could pick up some new rods and forged pistons. Then build it for boost with the correct ring gaps and what not. Then get a small blower cam, new springs on the stock heads, and run it!

I've taken a 5.3 iron block and bored it out to 3.905 with forged pistons, H-beam rods and Manley 4" crank to build a forged 383. It's going to have CNC ported 243 heads, overdrive balancer and 2.8" pulley driving my Magnusen 1900. The engine should be done this week. There was a similar build in one of the magazines with a bigger blower that made 680 crank HP. I'd be happy with 550. It hasn't been cheap but will be just what I want. The engine should be done this week and I'm pretty excited about it.

Plan your build very carefully, and watch your budget. Gonna be hard to beat a shortblock like this one. https://ls1tech.com/forums/forced-in...ck-2599-a.html
