Well, it finally warmed up enough to go out and do a little more work on the teardown of the engine. I got the pistons and crank out, but I have to find a #4 screwdriver tip ..or a good pair of vise-grips to get the cam out! Oh man was the timing chain and sprockets ever in need of replacing!!! Chain had so much slack in it I could almost remove it without taking off the gears! And the cam timing gear teeth were worn down to a knife edge! But now that I have this stuff out, I am more confused than ever. Here are the part numbers that I can find...Crank 2U, Pistons say 410 on them(!), rods say C7AE-B and heads are C8AE-H. Still can't find a number on the block though. What is confusing is that according to Steve's book those are 428 rods?!?!?!?! So, I got a 390 crank, 410 pistons and 428 rods! What the heck have they done to this engine?!?! Oh yea, the pistons appear to be the dished ones with eyebrows. I'm really looking forward to hearing what you guys all think of this developement. Thanks..until next time.

Chad, Sounds like you have a 410 engine. Strong puller in a truck, used in the big Mercuries for a couple of years only.

 

Ford used 410 pistons to lower the compression for the emmisions standards. You hae a 390 man. C7AE-B was a popular casting number in the 390's rods. The only thing that makes a 428CJ rod different is that the bolts are bigger. The actual forging is exactly the same.

 

Hi Chad:
Isn't the change in weather great! It sounds like you are a couple stepss ahead of me in the "fun " department. Rat and John are the best sources of info in my books. I will only add that the C8 heads are the standard model heads on FE's after 1968.
Keep inquiring, it helps my library of info too, --Mike G
