I contacted Ford and suggested they have a Retro Engines Program for their 100th anniversary in 2003. As part of that, I suggested they offer a 541 CID Lincoln Y-block engine more or less for early F-100s. The Lincoln Y-block ran from '52-'57 in 317-341-368 CID sizes, and is the perfect basis for a large CID engine for early F-100s from a heritage standpoint. 541 CID specs : 4.375 bore x 4.50 stroke, 2.20 intake valve, 1.80 exhaust valve, 1.625 piston compression ht, 0.020 deck clearance, 7.605 con rod length (1.69 rod ratio), 11.50 block deck ht. 541 CID features : gear driven reverse-rotation cam from 302-332 Lincoln Y-block heavy truck engines, forged pistons, billet or forged con rods, billet or forged crank, cross-bolted main bearing caps. I encourage any of you who would want to see Ford come out with the 541 Lincoln Y-block to contact them at www.fordnewideas.com Mention the Retro Engines Program to let Ford know we enthusiasts are together on it. Fords 100th year comes at a tough time for them, but together we can make it happen.
