As far as a stock stroke engine, with stock rods, pistons from the 350 C-175 engines would be about the best bet. You would need the newer cyl head for these pistons due to them being firecraters. You can use stock rods up to a 5-3/4 stroker H engine, but git out your grinder, and hang on!! Lots of cutting in that one. Just think of how many hp you are looking for, what kind of class are you wanting to pull? Low gear, 2nd gear, ?? 3500, 4000, 4500, 5000lbs?? For a smaller stroker engne that dont require major block grinding is 5 inches of stroke, stock rods, (you have to grind them down for clearence) and then for pistons,,, well that is a whole new ballgame! at 5inches of stroke in the H,s you can now use the IH 6 cyl pistons wit hthe compression height of 2.024. there is alot of different bore sizes ranging from 3-9/16 up to 3-13/16. The 6cyl wrist pins are much smaller than the H, but you build a brass bushing for the rod, to do 2 things,, 1 is to adapt the smaller wrist pin tothe rod, and 2 is to help set the compression height on the piston and rod. I usually remachine the 6 cyl piston to the pattern of the H compression chamber, and pick up alot more compression. You are able to move the wrist pin location up, or down in the H rod wrist pin bore, just depends on where you measure where the wrist pin bore location in the brass bushing, on the H rod. economy route is the 350 engine kit inthe H block. with all the good parts, (newer cyl head, Super H -350 cam, Super H-350 manifold, and carb) 50hp with a bit of carb, cyl head, and tuning.
