Let’s hear a 340 story
A couple of years ago I purchased what was advertised as a "complete" '71 340 in the Sacramento, California area. I considered it a core, but it turned out to be a real hodgepodge of parts to boot.
Both exhaust manifolds were the same, a pair of non-high performance fitted for the passengers side. The oil pan must have been for a truck, rear sump. The cylinder heads were open chamber with 1.88 intake valves. The pistons were cast aftermarket .040 over with four valve notches. The forged crank has no drilled ends, must be either 273 or 318. The Carter AVS belongs to a non-high performance 440. Intake was 1968 340 factory cast iron four barrel. Air cleaner a vintage 340 '68-'69 black wrinkle finish non-silenced version. Valve covers look to be generic LA style. Single point Mopar distributor. Accel yellow 8mm plug wires and Bosch spark plugs. Camshaft appeared to be a rusty old 508 hydraulic. Bearings were dated 1985 or so. Mopar windage tray. Double roller timing chain and valve springs with dampers. Aluminum timing chain cover had a hole clear through it directly behind where the water pump impeller would sit. It appears that one cylinder bore may have been sleeved. Standard 340 connecting rods (full-floating).
