Hey Cullen ! Congrats on a Great Find ! For a 360 conversion you'll need a V8 crossmember to replace the 258 unit. Jeeps normally only came with a 304. AMC late model engines : cu.in. 304 360 401 The 401 has a forged crank and rods. Finding a 360 : CAll around to the auto wreckers - . If one has a unit somewhere they will usually ship it for about $50.00 extra if it isn't half way across the US. I have two 360s - one has work into it yet has sat - a little stiff one has 33k on it and a 727 Torqueflite I'm about 45 min. north of NYC. Crane Cams has Roller Camshaft Kits Indy Heads have aluminum heads Crane also has Roller Rocker Arms Edelbrock has nice manifolds and carbs Holly has nice carbs Hooker/Hedman/by Ed for headers Mallory or MSD for ignitions Disc Brake Conversions when you get your V8 crossmember from another AMC . LUCK ! 7X HH-7X@xxxx
