was just wondering, on a fully built block..pistons rods crank and all

when the pistons are installed is it ok for them to shift left and right or up and down?

with the block sitting on the stand i can take two fingers and move the piston all around....

i have never had a block with after market pistons in it so i have never seen this.

thanks for all help

 

Yes there are tolerances involved.

1) Aluminum Pistons with Steel Rings
2) Steel Liners

Expansion rate is different for each and therefore tolerances are required.

If a reputable engine shop built the motor, they can give you those tolerances.

 

i have some papers with it i was just kinda spooked at first. im sure its all good

thanks

 

Best of luck with your new build !

 

thanks im prolly going to nickel and dime my self to death with all the little parts before i evan get it in the car LOL
