Description: I have a SB Chevy 350 motor that puts out 461 HP @ 5500 RPM and 485 TQ @ 5000 RPM for sale. I have all info on motor including dyno information and head flow numbers.

This motor would make one killer street motor or entry level bracket racing motor. Would hold up to circle track racing as well.

I have a thick aluminum timing cover on this motor. And polished ball milled valve covers on it as well. The balancer is a SFI approved racing balancer. The flexplate is nuetrally balanced and SFI Approved as well. No updates to SFI parts have been done.
This motor has only a handfull of 1/4 mile passes and a few nights of street driving on it. Not to mention the half day of dyno time.
This motor has put out 461 HP @ 5500 RPM and 485 TQ @ 5000 RPM. It is an exceptionally good motor I really hate to part with. But, I lost my car to a body shop so the car is more important to me than the motor. I WILL STAND BEHIND THIS MOTOR !!!! All Head work was done by FCR Performance in Omaha, NE including all port work. The machine work was done by Spanel Engines in Lincoln, NE. The assembly was done by Monzter Racing in Lincoln, NE.
I ran 10.20 second 1/4 mile passes with this motor at @ 130 MPH in a Monza Coupe that weighed 2740 lbs, with a full tub job cage, huge slicks, Turbo 350 trans, 4000 stall convertor, and 4.10 gears. With the right ignition, carb, and tuning YOU TOO CAN RUN these numbers in your sleeper, bracket car, etc... I GUARANTEE THIS MOTOR ROCKS !!!
