I wonder if you can punch it out and use the GM 8.1/496 rotating assembly in that block otherwise I prob wouldnt bother spending big money on stroker kit.
Just reuse the crank and rods...grab a nice set of higher compression pistons. Put some good springs on the heads and nice specd cam.

My fbody/ls friends have a guy that builds most of their engines but he loves big blocks might have some good info when you're ready

8.1 is a tall deck. Has the same bore as the rat block 454 but a longer stroke to get the cubes. Different firing order too but that can be changed with the camshaft.

Side note... told my fiancé that I can’t wait to have my Side Hoe back! She laughed and glared at me. Come to find out, Side Hoe comes out to 7 letters, which will fit on a license plate. Checked FL DMV, and SIDEHOE is available :chewie::happy175:

No one be taking my idea!
