Greetings from CA! Glad to have found your website! We have a project '56 Ford PU getting ready to enter the shop and are trying to id the engine. Was told it was a 427, but it appears to be a 406 or perhaps a 390 HP block? Block casting: C3AE, and HP 24. Heads: C2SE & 6090 B (or E). Crank casting: C1AE-A. Rod: C2AE-B. Also has an aftermarket Edelbrock cross ram style X-F66 intake #4041 without any linkage. Anyone know where to find linkage? Any and all help is much appreciated!
