new race/street duster

It's a world block 4.5 bore 4.75 stroke. B1 orginal heads with a little porting t&d rockers right around 12-1 compression. Cam was out of my old 512. So it could use a better came. Think it was like 813 lift and 314 duration with a 114 center. The headers are only 2 inch fenderwells. Really have to find a bigger set but have not had much luck. That's what was with the car.also reverse cooling water pump.
