I have a 1991 F-150 with a 4.9 (in line 6) and the 5 speed manual transmission. I would like to install a 460ci in. V-8. The question is, will the transmission that is in my truck right now bolt up to the 460 V-8?
I once had an 83 F-150 with a 460 but it had a C-6 automatic transmission in it. I would like to combine the 460 with my existing 5 spd. Transmission.

Do you
have the same problem?

You don't even want to think about something like that. The issues that would come up would be never ending. You have an operating system for one engine combination and that's it, not to mention that it would be against Federal law to do that.

Was this
