What problems will there be if changing a 390ci for a 302ci in a 1966 thunderbird?
You will need custom motor mounts, and existing transmission will not bolts up as FE motors have a different trans bolt pattern than a small block. Best to do an engine and trans swap together which also will require a custom trans mount as well. Also you better build that small block up. The T-bird is a heavy car and you will need power to get it going. The 390 was rated at 300-315 HP but around 400 ft/lb of torque which got that big car moving. If I could choose I'd do a 351W with an AOD or built C4. I think a 351 with AOD out of a Ford F150/250 best. The 351 can get you what the 390 had but in a smaller, lighter package and you'll get better fuel economy to boot. With a decent set of aluminum heads, cam, and intake, running 10:1 compression you could run a 4 bbl carb and make around 375-400 HP
