This is new 6.0l ls motor with LS3 heads, this engine is for sale and is 100% turn key.

Black Mountain Precision's 1" wide long water pump pulley system with a billet mid-mount alt. bracket.

High performance 1" wide cog belt pulley system on a big block 427 chevy with a long water pump.

This is a big block Chevy with a tunnel ram and Edelbrook aluminum heads. This motor makes 668hp at 6900rpms. The pulleys and brackets are my long water pump 1" wide cog belt system with my new mid mount alternator bracket. All of my product is on my website www.blackmountainprecision.com.
Everything that I make is a direct bolt-on in place of your stock pulley system.
I use billet 6061-t6 aluminum and is polished or black powder coated.
Thanks for looking.
Ron
