Can anyone help me figure out what my 427 big block came out of? The build date is 05/15/65 and the block casting #'s are 3855961 and Mortech.com shows that as a 1966 427 w/390 horsepower but I cannot get anymore information on it than that. The rest of the numbers & letters found are LF & 3866948. Thanks for any help - drew

Re: 427 Chevrolet help?
both numbers im showin as come off a 66-67 396ci
First is the engine block - 396ci - 325hp 2-bolt Next number is the intake manifold for 396 325hp, or 427 390, Holley i'll dig into it some more

Re: 427 Chevrolet help?
yeah, so far between mine and formulas sources, it would appear as though you have a 396ci BB and not a 427?
the second number you gave is the intake manifold number off of a 396ci But was also used on the 427's of that same year..

Re: 427 Chevrolet help?
Actually the 66 427 Corvette used the same casting number as the 396. Check my list again.

Re: 427 Chevrolet help?
427 help. can you get the numbers by the right side head,there's a plate with the vin code,usually has a code with 3 letters like TKD and it will have a Vin number also which is same as the car it came out of,because my book says it's a 350 with that engine casting number.
