Piston ID
Hello again from sunny Scotland!

Can anyone tell me if the pistons in my SBC are cast or forged? They are stamped 'L2256'

Apparently if they are forged then I only need a set of rings, if they're cast its time for a re-bore!

Best regards from across the pond,

I think you've got TRW forged flat tops with 4 valve reliefs. 9.6:1 with 64cc heads and 8.5 with 76cc heads. If you can, check under the Speed-Pro piston listings in the Summit Racing catalog. You'll find a TRW-L2256F30 piston listed.

Thanks for the info MI2600. That's the best news we've had for a while and should get us back out on track a bit sooner than we anticipated.
