Ok. 4.9" inch bore. 6" stroke of a custom grind crank from Crowler. To an engine deck height of 13". The heads are 2-1.9" Intake valve and 2- 1.5" exhaust valves. On DOHC head design. Flowing near 600 CFM. The pistons are below zero deck and still heavily dished to lower compression to just a little over 10:1. Engine makes near 1200 HP at 5200 RPM. With torque at 1150 at just under 3000 RPM. On pump 91 octane. Dry sump oiling. LS1 design multiport EFI with Big Stuff management computer. Custom intake (of course.) The engine is drilled for either Chevy or Chrysler BB bellhousing. Crank is drilled 8 hole for Hemi flywheel.
The engine looks very intimidating. But because of the size? It's really not that hard to navigate. Not a lot of little small components.
The car has its Dana rear that was used with their 800 HP Hemi so long ago. It has an old 4-link (Leaf link) pinion adjustment and support setup. Very clever in 1970s. Old school by today's standards. But does the job. Replacing the 4.88:1 gears (much too steep for this lower RPM torque monster.) With 3.54:1 Strange 40 spline axles with spool. I'm hoping it handles the torque hit? It's the transmission that I'm a bit stuck?
Currently have a JW Ultrabell Power Glide. With Gear Vendor O.D. That setup will certainly handle the power. But it heats up a bit for any limited street application. (Which is the target build. "Pro Street") So been exploring other options. A Lenco is the most logical choice. But just don't want to deal and have all those levers.
So yes. I'm looking to have my cake. And eat it too.
