Hydraulic lifters: Camshaft Duration: Intake: 256 degrees, Exhaust: 256 degrees, Lift: 0.427″. Ford would learn that this inhibited oiling at high RPM and would result in the famous 427 CID “side oilier, that oiled the bearings first.Ģ65 HP Regular Fuel V-8. This was to ensure that the lifters received enough oil to keep them quiet. Originally the blocks were cast as a “top oilier”, meaning the oil was sent to a line above the camshaft first. The main crankshaft journal bearing diameter is 2.749″. Later, this would allow for “cross-bolting” the main bearing caps for added rigidity necessary for long distance racing.Īll Ford FE engines have a bore spacing (distance between each cylinder center) of 4.630″, and a deck height (the distance from crank center to top of block) of 10.170″. In these engines, the casting extends 3.625 in (92.1 mm) below the crankshaft centerline, which is more than an inch below the bottom of the crank journals. The Ford FE engine and and its truck counterpart, the FT V-8s are “deep skirt” designs-so-called because the cylinder block casting extends below the crankshaft centerline, giving great rigidity and support to the crankshaft’s bearings. The cylinder heads had large ports and the valve sizes were large for an engine of its original size at 2.02″ for the intake and 1.56″ for the exhaust. The intake also acted as the valley cover – at that time a newer idea. Some unique features of the Ford FE engine were the distributor located at the front of the engine to ease maintenance, and cylinder heads that were very narrow requiring the intake manifold to be part of the valve cover area, with the pushrods reaching the rocker arms through it, rather than the head. A significant modification would have been needed to grow the engine beyond 312, and as such, Ford decided to use a clean sheet of paper. The “Y Block”, introduced in 1954, was designed to only grow to a bit over 300 CID, but no further, and in fact had reached its limitations at 312 CID by 1956. The Ford FE engine has conventional wedge combustion chambers in the head whereas the MEL has the chamber in the block due to the block being cut 10 degrees off square with the bore axis, rather than the standard 90 degree cut.įord had recognized, like other makers, that cars were growing in size, and that larger powerplants would be required to move them as well as their successors.
