I have a set of never used Diamond pistons, 4.030" bore, 4,000" stroke, -6 cc dish. 6.125" rod, .927 x 2.950" pin. This will build a 408 CI engine.

I'm including a brand new set of rings too. So you get new pistons, pins, locks, and rings.

$600 shipped OBO.

 

Up top again.

 

have you tried posting on tech ?

 

Not yet, was going to do that later today. Figured with all the guys going to 6.0's on here it would be a good start.

 

Bump up top.

 

Offers considered. Save yourself some time and money getting these from me. I have an excellent rating on LS1Tech, check it out.

I ship within 1 day of payment, sometimes the same day.

 

ugh these are temping if i was going to stay NA

 

What compresion would these be with stock 317 heads?

 

About 10.4 to 1 CR with 72cc heads.

With 64cc heads, 11.4 CR based on zero deck, .051" gasket.

 

Make me an offer. Keep in mind that NA may not make the most power, but not dealing with a power adder means a considerable amount of reliabilty. Just saying...
