Just had to retire cause of disability. Can't afford the fuel now. Does anyone know how to cange a 1989 305 EFI to a 6 cyl inline or v-6? Will any bolt to the tranny I have now? You can email me directly if needed.

 

due you mean 302?? becouse if so I THINK,PRETTY SURE? the tranny will mount right up to the 300/4.9 litter inline six. the swap should be fairly simple but like always try to get the same year motor as yours and there is always little crap that isn't planned

 

PS by the time you swap and buy all the little crap to do it right and the time it takes! it might be a long time tell you see any $$$ money from the saved gas millage just a something to keep in mind

 

the bellhousings are the same
the big things are:

motor mount towers
300 flexplate/flywheel
throttle cable
computer/harness
and the 300 engine itself.

fuel milage between the 302/300 is simular but the 300 has alot more performace and grunt than the 302.
