1958 430 C.I. 400-HP Lincoln Mercury 3x2 Super Marauder MEL V8 engine #1

Just a short clip of my early 1958 430 C.I. Tri Power MEL series V8 engine. It has been freshly rebuildt to stock specs. This engine is out of a 58 model Lincoln buildt in October 1957. The differences between the 6-bbl and the standard 4-bbl engine are the aluminum intake manifold, 3 2-barrel carbs, fuel pump, chrome valve covers and the large aluminum air cleaner (not shown in this video). This engine, as a factory option (J-code), was only available in Mercurys, but you could also get it in a Lincoln as an over the counter power kit. Despite the fact that it was only available for 1 year, and Ford never changed its rating, there are a few differences between early and late 1958 engines, and the early ones are actually more powerful. Some specs:

cast iron, Y-block, big block V8 engine,
4.90" bore spacing, 10.462" deck height, 2009.5 C.I. block volume
(later 58 engines have 10.482" deck height and 2013.4 C.I. volume),
4.30" bore, 3.70" stroke 429.9 C.I. / 7044 cm³ displacement,
