401 Pistons for about 9.5:1 ratio with 291c (51cc) heads?
I am looking to purchase a set of 291c (51cc) heads for my 401 build. I am looking for 9.5:1 CR for my build. I could go slightly higher, but I want to still run on pump gas (premium would be o.k.).
Bulltear sells a killer forged piston for the 401 in forged for $610 with pins. There are some castings available that may get you close however the current castings arent durable.
