I have a question for people that have modified an Oliver 88 with the following changes:

- Super 88 crank offset ground to 4.5" stroke
- Oliver 77 connecting rod with 1.940" bearings
- 4.375" Dodge 400 big block pistons

The Oliver 77 has 1.25" wrist pins and the Dodge 400 has 0.990" wrist pins. Does someone make custom rod bushing to address this issue? Does the piston have clearance to work with a custom bushing? In addition, with the sleeves people are using is there only an 0.125" thick wall between the piston and the water?

Thank you for any input.
 
taller 440 pistons, with offset wrist pin bushings may work better. the 400 is 1.824, 440s are 1.98. install a solid pin bushing in the rod, then have them drilled offset bore the pin bushing .085 longer. 4.6 OD and 4.375 ID works well off stock bore spacing.
