OK, my 302 is smoking really bad in my 1986 f150 4x4 manual 4 speed. It is a speed density efi. I have a complete 1989 f150 4x4 auto truck that got disassembled about 10 years ago but still have all the parts and complete truck still here. Is it as easy as using the computer from the 1989 into the 1986, hooking up the wiring from the 86 onto the 351. Or am I missing a lot of stuff. I also know I need a 28oz flywheel to work with the 351 instead of the 50oz the 302 has. Thanks
