i have a cast crank motor with low compression pistons, can i switch out the low compression pistons with 10 to 1? a buddy told me that if i switch out the pistons on the cast crank to 10 to 1 that the crank rods and pistons will have to be balanced to make it work.

my question is, do they make a 10 to 1 pistons for the external balanced crank? or would it be easier and cheaper just to change out the cast crank with a forged crank? i have a good forged crank to use.

thanks



it all has to do with the weight of the piston...you need to know how much your existing pistons weight and how much the new pistons weight..

even if you change to a forged crank...it is all going to have to be balanced if the bobweight of the crank is off from your existing rods and pistons...

the balance is all based on the weight of the rods..pins..pistons..
