462 MEL. My brother and I have been building MEL series engines for a very long time, there are speed parts out there, you just have to look for them at swap meets and Ebay, we have Isky roller and flat tappet cams for them, Mallory distributors, you can find Weiand supercharger manifolds, factory Super Marauder 3 deuce intakes, Edelbrock 3 deuce intakes, Edelbrock 6 deuce intakes, Weiand Drag Star 8 deuce intakes (Which are now being reproduced by Slover) Slover also makes a set of intake manifold adapters that allow you to use any 429-460 intake manifold on a MEL, we have a set they are very nice. Weisco and Arias & Ross all offer forged pistons for the MEL's, special order of course, and Egge offers cast pistons off the shelf. The MEL series uses the same oil pumps as the FE series so hi pressure or high vol are off the shelf. Isky still has iron adjustable rocker arms for the MEL's. Lifters are same as FE. The hot ticket with 462's is to use the early 1958-1960 383,410,430 big port no chamber heads for a compression ratio of 11/1 and the huge 3inch tall intake ports. 460 cranks are a drop in with minor machinging, or offset grinding the 462 crank to a BBC rod journal gets you 517 cid cheap. Off the shelf H-beam 460 rods with the 2.5 rod fit MEL cranks if you only slightly turn them down from factory 2.6 to 2.5., the lengths are close at 6.60 (MEL) to 6.605 (460) The best blocks are early 430 1958 to 1960 as they have the FE bellhousing pattern for 4 speed, or C-6 or cruiseomatic. 462 block is Lincoln only special C-6 case, however a steel lakewood or quicktime bell can be welded to use a 4 speed. Hope this info helps, at $150 that engine is a good price. Oh and Moon and others have nice valve covers available.
