I want to build an Oliver 66 puller, I have a 550 engine and would like to go 4.75 or 5 inch stroke and 4 inch bore. Any one have any combinations/suggestions to accomplish this. Rods, pistons who to stroke crankshaft, or anyone got any parts? I guess it would be like an Oliver 77 with 2 less cylinders. Thanks for any help.

4.75 stroke x 4 bore. Use stock 66 rods and use chevy pistons. Harts machine service does my cranks.

I'm interested to know more about using 350 pistons. Is that all there is to it?
Is there any machining needed? Anything else I should know? 350 rings too?

I put the 350 pistons in a 77 that I had bored to accept 4" x .125 sleeve stock which was driven into the block. I had the crank stroked 3/4" and used some old MH rods. I can't remember which rods but it was one of the smaller Massey Harris 4 bangers. The pins were press fitted into either the rods or pistons, (been a while), after one or the other was bored to fit. All the lengths, heights, and rod angles were good without grinding the piston tops or changing rod length. We used stock 350 pistons and the rings that came with them. Bill and Bill at Monarch Mach. in Spgfld, Mo. did all the machine work except for the crank which was done by Stan Blades at "The Shop" down by Aurora. They are all history now as far as I know. gm

So do the 350 pistons give you quicker rpms or higher rpms? Or just cheaper?
