I've read in numerous articles and books summaries of the 427 Le Mans engines used in the 66 MK-IIís & 67 MK-IV GTís.
 
It is usually consistent the 66 engines were 427 medium riser dual plane 4v induction with dry sump oiling, cast iron block with aluminum heads.

In 67 it appears there were some tunnel-port engines used in competition, as well as the medium riser dual plane 8v engines.
I belive J5 in The Henry Ford has a cast iron block, aluminum head, dual plane 8v engine in it today.
I will search my photos.

Iíve also read reference to aluminum block 427 engines but have never seen authoritative documentation of an aluminum block 427 Le Mans engine.
Perhaps it is confused with the 390 aluminum engine with Webbers tested in J2 at Riverside Aug 1966?

What do our experts say?

thank you

Not a Le Mans engine, but didn't Ford offer McLaren a aluminum tunnel port 427 for the '68 Can-Am series ?
