I put #46 heads on it, Screw in studs, about 9-9.2:1 compression ratio. The intake is the same casting # as the ebay mess a while back ago, the correct one for your T/A, Jim. There's a Quadrajet carb on it for firing purposes, possibly to be changed to a 750 duel inlet Holley & a high performance Summit racing fuel pump. It's electronic ignition, but I think I'll still run an external regulated alternator. Power steering is the next accessory to be added soon.
