It costs less to build a naturally aspirated 650 HP 8.1 than LSX. Enough to be worth it. And stock 8.1 bottom ends are good for 500 HP and make more than that in HP3 trim they tested them for 40 hours at WOT held at the power peak before production. I love the LSX small blocks but the 8.1 doesn't live in thier shadow for HP per $, stock HP, or HP with equal mods.
Good luck with the prodject, sometimes you have to do something different to live with yourself. You wouldn't regret a 8.1 powered 1500. I know big block 1500 trucks were the trucks to race back in the day when you could still get them. That Coolside would be nice to duplicate.

The GMPP LS7 dry sump Camaro test bed looked and ran really nice. The dry sump install didnt look too bad to replicate. Battery to the truck and trim the oil resevoir 2-3". It ran a 12.00 @115 with a bum T-56. The driver said 11.6's were in the cards with a working trans. This was with a stock 203°/230° LS7 roller cam.

GM is under MANY more contraints than an aftermarket engine builder is under. To get the durability that GM needs for a production car, they had to use some pretty exotic materials like titanium. That stuff isnt cheap. Sure folks can easily build an LS2 with bigger power numbers, but power is only 1 part of the equation.
The 8.1L swap is cool simply becasue it is rare. An 8.1 in a rcsb would be awesome. 496SS sure has a nice ring to it.
It would be nice to get a pair of those ported and polished iron heads that GM used on the Coolside 2 pickup concept.
