Always made great power with a square motor.. Don't know about a 4.5 stroke.seems alot to me. for a blower deal. Just thought I would throw it at you. Keep asking around Good luck. Don

 

you have a little stronger crank with a 4.375 versus 4.5 as the rod pin overlap is a little greater with the 4.375
I think that is why that us that run the 4.5 have a harder time with the #5 main bearing
