In Reply to: 300hp motor What are the heads from posted by David on November 07, 1998 at 02:13:25:
: I would like to know where the heads are from on the 300hp 350ci #12355345. Where these heads ever used on a production car, if so what cars or trucks. Do you know what these heads flow and what are they capable of performing. I would like to buy the zz4 motor for my car but the heads are angled and it is 10.1:1 comp to high I would like to know if I can make the same hp with the 300hp motor with the change to a roller cam?
: Thanks

The 300hp heads came from the L-98 camaro 88-92 350 TPI. But with a standard intake bolt pattern. This engine with a ZZ-4 cam would put out 335hp. The new vortec heads work good we just tested a 300hp 350 with these heads The power was increased to 355 hp TOM.
