I recently bought a motor to replace my 352, the guy told me it was a 390 that was out of a 1967 Mercury Station Wagon. The motor was a orginal 4 barrel motor but it was changed to a 2 barrel carb in the past. How do you tell the differences between a 390 and 410 or any other FE by look without tearing the motor apart. I really don't know what I bought the block has a C6ME casting and the heads are C6AE-J and C6AE-L . I don't think the guy I bought it from would lie to me because he is a Preacher, but he is a Chevy guy and didn't know much about Fords. I would appreciate any help on this matter.
You dont have to tear the motor apart, just pull 2 spark plugs.
Put #1 cylinder on TDC, pull the spark plug and stick a long pencil or other such skinny rod down, mark it where it hits the flat by the hole. Put the rod in the #4 cylinder the same way, without turning the crank, and then measure the difference.
3 3/4" (3.78 stroke) is a 390, 4" (3.98) is a 410 (428 too).
Just out of curiosity, I've never seen a C6AE-L head, or even heard mention of one. I have a set of the C6AE-J's, but I would like pic's of the -L's, if there is any way you could take some it would be greatly appreciated!
Thanks FrayedSanity the help on how to identify a FE engine. I have not been able to do it yet because I sliced my finger to the bone while working on my motor, breaker bar accident. I will get a photo of the FE C6AE L head once the weather clears up and my finger heals, might be a few days.
Beer helps, I should have got stitches, I could see the ligament and bone when I did this. It didn't bleed very much, so I said the hell with stiches and put a band aid on it, still hurts 3 days later but no infection. I will get some pictures soon but I need to heal up a little, I can't hold much with the hand I injured my finger on.
Those breaker bars always hurt me, I should just get rid of the darn thing and stick to air tools, everytime with a breaker bar it never fails I hurt myself, oh well.
Word of advice I'ld never knew about before 3 days ago. Heat pads/Hot water bottles, warm espom salt soaks all speed healing by increasing the blood flow. And here I always thought heat was only good for sprains and bruises!
If you already knew this, then maybe someone else will benefit
That is a good point 427. Never thought of that. Most of the pistons have dishes and then a valve relief. You could still angle the wire to angle towards the outside of the cylinder so it against the wall.
Kinda funny but the only time I have ever had stitches was from getting cut by a cheap computer case. They had to put a few threads through the fingernail. That really sucked. It does lay you up for a long time though doesn't it.
