Wiseco Piston for 5hp Flathead

[rmoore45]

What Wiseco piston do I need for a stock bore & stroke Briggs 5hp flathead? The bore is fine so I'd rather not have to bore it out unless necessary.

What do all the Wiseco piston part numbers mean? I'm seeing many different part numbers. Doesn't seem to be much information about them anymore.

Performance pistons seem to be hard to come by for these engines. Most of the Wiseco stuff I'm seeing is old stock on clearance. Is Wiseco still making pistons for these engines? Are there any other manufactures currently making performance pistons for these engines?


Thanks,

If your after stock bore and stroke pistons,why not use the raptor 3 piston?

You need chromed pistons for the kool bore and any either chromed or aluminum for iron liner.
