Poured main bearings unless marked LB on the block (there are some exceptions to the LB marking) front mounted distributor driven directly off the camshaft 221 cubic inche displacment bell housing is cast in as part of the block Bore and stroke are 3.0625 x 3.750 ==1938-1942== 24 studs hold on the heads two water pumps relocated to the front of the block waternecks on the heads located in the center distributor is front mounted and still driven off the cam marked 81A, 81T, 41T, 99T, or 21A on heads full floating bearings bell housing is cast in as part of the block ford engines had 221 cubic inch displacment Mercury engines had 329 cubic inch displacment Ford engines retain the same bore and stroke Mercury engines receive a 3.1875 x 3.750 ==1946-1948== 24 studs hold on the heads water pumps and neck retain the same location as above Distributor is the same as above heads are marked 59A, or 59AB both Ford and Mercury engines have a 239 cubic inch displacment bell housing is cast in as part of the block Ford and Mercury engines share bore and stroke 3.1875 x 3.750 ==1949-1953== major changes are made to the flathead water passages are enlargen for improved cooling water necks are moved tot eh front of the heads waterpumps remain in the same location heads are held on with 24 bolts rather than studs new conventional style distributer is used distributor is now driven by a gear off the cam the cast in bell housing is removed modern insert bearings are used ford engines marked 8BA, EAB or 8RT on the heads Mercury engines are marked 8CM,or EAC, on the heads Ford engines remain 239 cubic inch displacment Mercury engines are increased to 255 cubic inch displacment ford retains the 3.1875 x 3.750 bore and stroke Mercury receives a 3.1875 x 4.000 for bore and stroke ==1937-1940 V8 60 flathead== 17 studs hold on the heads much smaller than the normal flathead V8 has full floating bearings 2.60 x 3.20 bore and stroke 136 total cubic inch displacment 1937 had tin sided blocks, while 1938-1940 had cast sides distributor was the same as the 1938-1942 flatheads ==1948-1951 125-150 hp flathead== 27 bolts hold down the heads rear mounted conventional style distributor Lincolns came only with hydraulic lifters Big Ford trucks came in both solid and hydraulic lifters 337 Cubic inchs of total displacment 3.50 x 4.375 bore and stroke marked as 8EL for Lincolns marked as 8EQ for the ford trucks == 335 Series Engine Family (Cleveland) (351C/351M/400) == 8 cap screws retain rocker cover. Timing chain housing is part of block casting. Thermostat housing on block. Fuel pump mounting bolts are vertical. Exhaust bolt holes diagonal. 351M/400: Intake is 12.7" wide the 351C is narrower (Differing Deck Heights). It is difficult to differentiate 351M from a 400 externally. The most accurate way is to remove the oil pan and look at the crank. 400 Crankshaft ID. http://www.tmeyerinc.com/400crankshaftid.html == Windsor Family (221/260/289/302/255/351W)(not all made in Windsor) == 6 cap screws retain rocker covers. Thermostat housing on intake manifold. Exhaust bolt holes horizontal. 302 BOSS Engines (69/70) have Cleveland (335 Series) style (canted valves) heads and the block can be identified by screw-in freeze plugs. Timing cover/water pump, put your thumb on the timing cover above the water passage, is it touching the head? It is a 302, Is it touching the block? it is a 351... == 385 Series (Lima) -- (429/429BOSS/460/370 Truck) == 7 Retaining cap screws in rocker cover == FE Series (332/352/EDSEL361/360/390/410/427/427SOHC/428) == FE (FORD-EDSEL) Engine Family: Intake manifold runners partially covered by rocker covers. Distributor goes through the intake manifold, the only Ford engine that has this feature... == FORD Y-Block (239/256/272/292/312) == Rear mount distributor 2 Studs (and retaining nuts) retain rocker cover Intake runners are over and under- Center exhaust ports are close together (similar to a SBC) Exhaust manifold bolts are in a common plane (line) across the cylinder head exhaust surface, if they are staggered it is a Lincoln Y-Block (317/341/368 Pass. Car) (279/317/302/332 Heavy Truck)
