Nice motor Goose. I like that distributor cap. Oughta change them valve covers though so people who dont know dont mistake it for a 330.

I think 330 was the horsepower rating.

Err, since its a marine engine, would that be seahorse power?

Eaton, under the Interceptor marque, made the 427 in three versions. The 300 h.p. version with 9.0:1 compression, the 330 h.p. with 10.5:1, and the 425 h.p. version with 11.5:1 and dual quads.

Oops, I forgot about that....I always thought the 427 was one of the best engines Ford ever built. For the life of me, I can't figure out what the purpose was to quit building it and build the 428.

427s are great motors for high revs for boats and racin and stuff like that. Theyre not too street friendly since they were designed to make power at higher rpms. The 428 has a longer stroke and a slightly smaller bore and is a really good all around street monster.

Main reason FMC quit producing the 427 in favor of the 428 was cost. The 427 was designed and built to be a racing engine (mainly for Nascar &NHRA), not a production engine, and it used the 390 crank. The 4.23 bore of the 427 required careful manufacturing and exacting tolerances that took a lot of time. This was not feasible for a production motor. So with the popularity of the 427 taking off, FMC redesigned it to a 4.13 bore and used the 3.98 stroke crank to achieve approximately the same displacement (425.4 to 426.5).

Now if Nascar would not have ruled the 427 Cammer illegal, there probably would have been a lot of these engines built. The cammer was popular in drag racing for awhile, but began to fall out of favor when NHRA banned it from stock classes.
