Will this work in 80s model 302

View Answer

Is the increased displacement achieved by increased throw in the crank, con-rod length and/or moving the wrist pin up in the piston? Or a combination of all? Is the oil ring compromised at all? How does the throw compare to a standard 302?

I have a 1967 289 block will I be able to use this or do I need the 302 block. I know I will need to have the block clearanced to use the stroker crank. Just want to make sure if it will work?
