Yes have plenty to support it, tube chassis, giant axles, 4 linked, stout 727 with coan and reverse manual, aftermarket quick-change transfer case, and driveshafts are all 1410 stuff.
My Indy headed 434 made 700 on the dyno, but has shown 650 or so at the drag strip. It's a pump gas street/strip deal so I'm sure there is more power there with a couple points of compression and race gas or alcohol.
It's only 11.2-1, just over .700" lift solid roller, 4.09" bore 4.125" stroke. There are a handful of guys who build high HP small blocks, pick their brains. Keep us updated on what you choose to build and its progress.
If you're interested in a complete engine, I may consider selling mine.
