So I've been looking more and more into doing an engine build and it seems a few shops have different opinions on going with a overbore or a longer stroke to achieve a larger displacement for a built a engine. Wanted to see what was everyone's take on the most reliable route.

Sorry to resurrect but I've been searching for opinions on the Manley stroker and came across this. I saw no one answered your question. Don't know if you've found out since, but to answer: you can use the standard Manley TT rods (or any other standard length rod), but you have to get different pistons. Manley (and others) make a set that has a lower compression height (the distance between the center of the wrist pin and the top of the piston)

I'm running a 98mm Crower crank with 87mm pistons. Stock RPMS all day long with zero issues.

He haighl!
