I.D. a 427 Cross Bolt Please

[Vet145]

My dad has a 1962 Mandella flat bottom boat with a 427 cross bolt in it. I was hoping someone here could I.D. this motor for me.

Head numbers C4AE 6090F.

Block numbers are hard to read unless I had an idea of what I was looking for?

Intake appears to be matching C4AE 9425-E.

Any help would be appreciated.

427 Hi-Riser Heads & Intake

Most likely a 427 center oiler with cross bolts. The heads and matching intake are pretty cool. High Risers were also called "tall and terrible" for the very large port size requiring special intake gaskets. NASCAR outlawed them in 1965, something about an unfair advantage. Ford's response was the "medium riser" which was "almost" as good, almost, not quite, nice try, but stills falls short of the "Tall and Terrible" category.

It's virtually certain that is indeed a 427block. The High Riser heads also ran BIG valves which would not clear the bore of a 428, 390, etc. They barely cleared the 427 bore.

Thanks for the responses. The block number appears to be 03AE-A or C3AE-A. 3 could be an 8 still hard to tell. Just trying to figure out what it is to sell it for him.
