Chevy began producing one-piece seal, roller tappet motors in '87 and I have seen the blocks for sale for $100 or less, some complete with dog bones and spider, some even with the lifters for that money.

I also would not be trying to build an 11:1 or 10.5:1 motor if I had to run it on pump gas swill. You can make plenty of power with 9.5:1 to 10.0:1, using a streetable cam and operating off pump gas with no problems.

I also would not be using 6 inch rods. Their length puts the wrist pin up into the oil ring land and you have to use filler spacers in the pin bores to provide support for the rings and to prevent the ends of the oil rings from falling back into the pin bores if they rotate around the piston (which they will).

Roller block, L31 heads, 9.5:1-10.0:1 static c.r., 0.035"-0.045" squish, hydraulic roller cam (good to about 6200 with roller hydraulic lifters before they pump up) with around 230 degrees duration @ 0.050" tappet lift, Scat cast steel crank, Scat 5.7" I-beam capscrew rods.

Don't try to make life any harder than it is.

what kind of power would that make

(86-94 350 by the casting number. May or may not be finished internally for roller cam, but is a 1-piece rear seal. Pull the intake. If it's all still there and a roller motor, it should have the spider, roller tappets and dog bones.)
