390 to 410 questions...
By Mav_70 - 01/27/2002 7:24:46 PM; IP 165.121.112.167
I am interested in converting my 76 F250 390 into a 410. I have heard this can be done.

My first question: Is the 410 Merc block in 66-67 the same as a 390 block from the same year? If so, this means my 76 390 will work right?

Second: Both engines have the same bore, does this mean they use the exact same piston? Or is the 410 piston a bit shorter so it will work with the increased stroke?

Third: I know the 390 and 410 used the same length rods, but is there any major difference between the two in reguards to strength?

Fourth: Can anyone please give me full details as to what must be done if some of my theories are incorrect? Where to buy 410 pistons etc.

Thanks in advance.
