Given a short deck 9.50, 6.50 rods (7.147 to the top of the rod), and a 3.59 stroke crank. Add in the piston thickness @.250 with .020 rod/piston clearance and there is not alot of material that can be moved to lower the c/r. That being said, what would be the most preferred method? (need to order pistons)
- Thicker head gaskets .060 or more vs .039
- Larger gasket bore dia (4.015 cyl) 4.090 vs 4.020
- Drop the upper ledge of the piston .020 down in the hole or more if possible vs zero deck
What would be the advantage / disadvantage, or max to shoot for each method?
Head cc's not included, since that usually can't be changed much
