I am contemplating on doing a streetable stroker for my other car. What is the biggest stroke you could put into the H 55 mains block before have to do major clearance on girdle or cylinder bottoms etc etc?

Rod design would probably be a H or I beam... I know H beams aren't best for big stroke/NA. So nothing too large like a huge Aluminum rod.

I know with 99mm stroke K24 guess there is no clearance massaging?

I am contemplating on going either 100mm or 103mm stroke... 103 be an issue? 100mm Stroke R/S ratio appeals to me more at 1.43. 103 would be between 1.37-1.39 R/S ratio

My targeted compression ratio will be 11.7 to 12-1 compression

Thanks for the help.

 

4piston just posted to their instagram the clearancing they had to do for a 100mm stroke in an h. My 99mm stroke k24 will need clearancing as well because of the aluminum rods.

 

Thanks for the post... It's hard to see if there using an Aluminum rod. I am choosing not to go this route so will be slimmer... More of a budget minded thing and not as high rpm or extensive build pro2 or equal far as cam lift. I believe most don't have to clear anything with normal non Aluminum rod with K24 99 stroke.

I am not wanting to rev past 9k... I am thinking a H beam cheaper rod may work...
