Someone is selling a good running 1967 390 engine and 4 speed truck trans for $600. Currently my truck has a cracked flathead v8 with a non syncro 4 speed. I am torn between installing this dependable 390 engine and 4 speed combo in my f5 and completely redoing a flathead v8. Is is difficult to install a 390? Is it the same block size as a 460?, because an eariler post mentioned they had to move the firewall back 3" to make it fit. Your thoughts would be appreciated. Thanks, Kurt
