QUESTION:1966 PLYMOUTH VALIANT
What motor are you thinking of using? My neighbor put a 241 Dodge hemi in a 64 Valiant wagon. It has an Offy intake with 3 deuces and a home made air cleaner that looks really great. I think the engine wells are the same as a 66. They became wider in 67. I know the 241 is quite a bit smaller than a 331-392, but he didn't have to do any cutting. I am doing a 57 Desoto 341 hemi in my 67 Valiant. The engine well is a little wider, but I did have to cut away some of the passenger side shock tower, remove the windshield wiper motor and cut away a bit of the firewall in that area, move the master cylinder over about 1-1/4", and raise the motor about 1-1/2" to keep the headers off the steering box which meant I also had to raise the tranny tunnel a bit. Because everything is so tight, I mounted the motor solid so that it wouldn't be slamming against stuff.
