Talked to a guy who has built a bunch of these. He says 4" stroke is old news. They even done that with a 2.250" main. Really pushes the limit on the crank. They have 4.125" stroke stuff out and racing with great success. Rumor is a 4.250" is out but I can't get anyone to confirm. This fellow told me a 4.300 should fit with some clearancing to stuff I really don't need. He said they considered fixing one up with a deck spacer to get some more room for the rod and piston. THAT'S WHAT I AM TALKING ABOUT But, for now I may just try and get something together to just see how it works out.
