I pulled out the passenger seat and pulled my 318 out of my 1976 dodge van and put in the 360 I built for it by myself except for about 5 minutes help from my neighbor I gave the 318 to. When my dad wanted a 440 built for his 1977 Dodge motorhome I told him I would build the engine but not the R and R work. We found a guy to do that. Lol.
