What kinda hp ?

I always have the block line honed to middle spec as the Pontiac block has a tendency to move around in the #2 webbing. Make sure u have .015 side to side in the rods. radius the oil holes in the crank. More info can be posted if more info is supplied.
Eventually if I find the correct block I would build the lower end to handle 450 hp plus with a set of aluminum heads from SD performance, a roller cam in the mid 230's at .050, and 10.3-1 compression. Short term goal would be 350 or so with ported iron heads, crower 221/229 cam, and a compression just below 9-1.
