Hey look at two threads down....another similar question from john.
Royce is right as usual. A C6ME cast block could be most anything from '66 into and maybe through '67. Might be a few in '68 even. But what I've found is that often a plain just C6ME casting is a red flag of a heavier duty than regular FE block. There's going to be exceptions for sure. We FE fans live by that rule of exceptions.
An example: I have a C6ME that is a 391 FT block. It has 428 thick cylinders. In the center expansion hole I can see a little tiny '428'. That's a good sign! I've had the block sonic checked. I had it bored .030 over the stock 4.13 because I wanted it that way. And there's plenty of cylinder wall left to keep the coolant temp down on the street. My FT '428' also has all the heavy duty casting provisions for cross bolts. Which I'm doing too.
So have that C6ME sonic tested to find out what you've got for sure. A 4.13 over bore may be very possible. If it's not already 428.
As for date code look for something small that will start out with a 6 or a 7 The year...'66 or '67; followed by a alpha letter like A - January, L - November, there is no letter I used, followed by a number or two indicating the day of that month in that year that the block was cast. I think mine has a 7A20, 1/20/67. |
