where could i get some light weight pistons for my 305 ive looked around but all i seee is stuff for the 350 thanks

We sell 305 pistons in our Pro-Tru line. We sell oversizes for them, also. Wiseco Piston 440-951-6600

since its just a 305, a consideration for a set of stock style cast pistons might be a consideration. stock style cast pistons can be very light. light enough definitely for the rpm's in a 305's power band, with its very shrouded combustion chamber and valve layout capability.
