I have a 92 Z28 with the 305 TPI/5speed. I am wanting to go with a 350 or 383. I am also thinking about going with the HSR. What block should I be looking at getting ? I want it to be roller motor. I have a 350 4 bolt now but it is out of a 77 K5. I don't know if it is better to build this one and spend the money to convert it over or just find one like a L98. Give me your thoughts on the subject.
