Re.Bolting it up,tried it again......................

F350 brocno, rwjr & Cobrajet and........ I went and got a different torque convertor and went to size it up and back at the same problem, here's whats I got, the same convertor....... apparently I had 1.375 nipple on the original convertor and I went and bought a early style convertor and it is exactly the same size. I am trying at my best ability to measure the pilot hole and I'm coming up with a 1.236 to a 1.240 hole size on the crank, which is way smaller than the old and new style convertors, does this make sense to you fellas? did i buy some prehistoric odd ball? or did this possibly come out of a truck with a clutch?? Again the junk yard said it came out of a lincoln and the tag looked to be very original on the intake saying that it was a 1969 460. Is there such a thing as possibly buying some type of aftermarket torque that may slip in? or do i have to go back farther yet in old style convertors? After triple triple triple checking it does not have any type of bearing or a bushing in the end of the crank!!?? To recap: 1977 460 high miles and tired in a motorhome with a c-6 transmission, replacing with a 1969 lincoln 460. All comments appreciated!

Re.Bolting it up,tried it again......................

the pilot bore should be the same size on both....if you can do it easily, pull the oil pan on the new engine and look on the sides of the crankshaft throws for a stamped number...yours should have a 2Y , 2YA, 2YAB, or 2YABC....probably the 2Y or 2YA...another possibility that i am not sure about is if it is a lincoln engine, from before lincoln used ford engines....maybe someone here can help out with that info...

I'd say someone told you a fib and that you have a 460 that was installed in something that had a clutch before you purchased it. Sure it may be a '69 460 originally installed in a Lincoln but how many of us out there have a 460 in a truck that originally came from a Lincoln? Get that pilot bushing out, then the convertor should fit.

OK I'm listening just not seeing!! The engine is in the mounts the transmission is loose the torque convertor is at the machine shop, it will go together! I now have to wait till Bob gets the torque done saturday. I will gently play with a chisel to see if there is a pilot there, don't want to mess it up. I did not pull the pan back down to look at NO#'s but that may happen yet. Thankyou for the constructive information will keep you posted.

I have had troubles with the pilots also, although not to the degree you have. My 1976 460 crank has a 1.835 pilot hole (not 1.850) and my TCI converter has a 1.848 snout (seems reasonable for a 1.850 hole). It does not fit! I called TCI (the transmission experts!?) and the technical support folks said they had never heard of that crank pilot problem before. They suggested grinding out the crank pilot the required 13-15 thousandths.

Keep us posted on how you proceed. Best of luck.

29gp,

Did you ever figure out what to do with your torque converter? I also have a 1968 460 with the 1.240 crank pilot. Did you have to get your converter pilot turned down? Or did you find another converter?? Your help would be great!

When I swapped from a 400M to 429CJ from a 70 Torino I had to buy a 429/460 torque convertor to complete my swap.
The 400M /C6 torque convertor just wouldn't fit.

The transmission shop knew what I needed and supplied it.
