This assembly is from my last combination. I ran it for two years and didn't use any nitrous. I took it apart to build a stronger bottem end for more horsepower. BES did the work to it and it was neutrally balanced by them. The crank is cut .020m/.020r; the rods are from a '68 400 and have ARP bolts; and the pistons are .040 over forged TRW's. This assembly has around 5,000 miles on it and is in good shape. I'm asking $500 for it. If you're interested, e-mail me [ email@example.com
] and I'll give yor my phone number.
