Looking to replace my 273 with a 318, which one?

Call Brian at IMM engines in Indio California or the folks at MRL both are active here on this site MRL is a sponsor and Brian has built for many of us here , he's closer for shipping and I seem to remember him selling a warmed 360 for about the same price or less than the mass produced "crate" you are looking at elsewhere . Both these guys have good names in the mopar community and work hard to keep them instead of some outfit that mostly sells chivy and turd motors .
