Piston info

I am finally putting my motor back together and went to my mechanic and told him that I would like to send the pistons off to Rebco to get them lightened up and he said spraying nitrous I should leave them heavy for that purpose.

 

They only lighten the pistons in areas where there is xtra material and does not affect the strength of the piston.

 

So I will send them off next week because I have to get a piston. One was lost during the process.
