ORIGINAL: More HP
pssst... don't tell anyone, but while you are ordering a fs-30 crank and drive washer, you can also get a piston/pin/ring/cylinder for the .30 and drop that in. Voila, you'll definitely have the strongest .26 at the field! I won't tell anyone!
Don't tell anyone . . . but for $61 plus shipping . . . I can make a 30 out of my 26?
I made a "52" out of my "48" but I didn't consider it cost effective after I got done. The engine runs nice though.
I notice the regular 26 and 30 heads and head gaskets are the same part number
