Got a engine question and am probably posting in the wrong section. Back in 07 I added a 95" stage 2 kit. I've been looking at the SE performance book and it reads like I could change the crank and get 103" just by adding the crank. Would this require pistons with different pin location or is there enought room on the stroke to add the 3/8" increase? The increase in stroke would add 3/16" more piston travel at TDC. How much clearance is in there? How much would this increase compression? I'm considering the crank change because I feel the stock crank balance is not very good, lots of viberation at 4200 RPM and up. I talked to a cert. wrench and he felt the SE cranks were a lot better for balance. Appreciate any input.
