Your discussion about the stroke and rpms is one of the reasons why I decided to go with just sleeving the block and going with a bore of 100mm, while keeping the stock crank and stroke. This route gives you 3.8 liter that is still quick reving and will go to at least 7500 rpms.

 

Hold on joe nismo is on to something but how would that make the Rod piston balance / relationship work isn't that also somehting to be considered. I hear that if you bore you have to stroke?

Also what would the "whatever " ration be with that would it be 1.77? still? Hold on I'll get the correct term from the other age ahahahhahaha I look so stupid, bad shrot term memory

 

rod/stroke ratio

 

For us older guys, it's like the 302 Chevy small block. 283 crank in a 327 block. High revving, high power, oversquare.

 

yeah, but what's the mpg with this baby? 10mpg?
