This motor was purchased with the intent of making well over 1,000 hp and torque all while keeping weight to a minimum. The block was designed to make big power. I had three Syclones and now I am down to just 1. From my other ads, I am getting out of the Syclones for now and I do not need the block anymore and could use the space! Feel free to ask questions on here or text/call. Send me a PM for my number.

Motor is wet sump, but can be switched to dry sump setup with an adapter. It has a 4" - 4.250" bore, up to a 60 mm camshaft, splayed main caps, NHRA approved, and weighs just 76 pounds. This block is the replacement block (since GM isn't building them anymore) for the GM V-6 Bowtie Block, P/N 10134388. To order and receive one, took me over a year.

Still in the original crate! $3,300.00 OBO

It appears that the block is setup for a wet sump oiling system. It would still take some work to make it usable/before building.
