Well I have a 292 L6 4.8 Chevy motor that the bottom is done 0.040 LP gas pistons for more compression. The head has been decked 0.020 BBC valves .550 lift springs and lump ports installed. I will be ordering ARP head studs and then the assembly begins. What I have not been able to do is find some of the parts to finish the motor. Timing gear cover, dip stick tube/dipstick, alternator brackets. THE question does anybody know of a source for these parts? The local junk/scrap yards don't keep anything. I have gone through Summet,Jegs,Speedway. I started this with a bare block and crank.
