1973 360 motor home engine questions

I bought a 73 360 2bbl motor home engine and T-flite to replace the 273 in my 65 Valiant and was wondering if it would be any different than a passenger car engine. The crank is drilled for a manual trans other than that and the rear sump pan I can't see any difference unless maybe the exh manifolds? The engine only has 46,000 miles on it so for now I'm going with a 4bbl intake and carb, headers, and possibly try to find a cam to match the engine. Any advice/suggestions would be appreciated. thx, Litz
