I have a 109 GN block .030 and STD/STD crank. w/ 8,000 miles on it.
I bought the crank new from GM back in the day!
Rods have polished beams, w/ TRW forged pistons
I swapped it for my 4.1. Ran 12.6 @ 108 w/ stock turbo/ IC and mild cam.
Built by me when I worked at a machine shop.
I would only sell it as a short block w/ balancer flexplate since it is a balanced assembly.
$1500.
OR
I have a STD bore 109 block and crank that need maybe a 10/10 grind.
I priced shipping befroe was $90 for UPS freight but that was 6 months ago and fuel surcharges have probably made it 110 now. crank ships for another 30-40.
$400 + shipping for both.
