I'm gonna sell my BBC 402 as I'm tired of walking around it in the garage. Can someone tell me what it's worth? Thanks. Here's a little bit of info: Chevy Factory 402 BBC – 2 Bolt Main Production Date: Sep 20, 1971 Block Casting #: 3999290 Was a factory (warranty) replacement motor for a 1972 Chevelle. NEW: Comp Cams 268H; Distributor, Harmonic Balancer; Water Pump, High Volume Oil Pump, Holley TBI adapter. (Approx 550 Invested in parts) Heads completely redone with hardened seats and new valves. ($350) Bottom half of engine was rebuilt prior to me purchasing the block. Was partially disassembled by a professional mechanic and determined good. I'll put up for sale in the F/S forum after I determine what seems to be an appropriate asking price.
