try summit racing,or jegs. they have all sorts of adapters and such. if that fails see if you can find the intake you want on ebay,or the craigslist.(dang starting to sound like BJ)Another option is to hit the junkyards and look at anything with the 360 in it,you may get lucky.I am not sure but i was told the amc 360 was a chrysler engine so you may be able to find one on any older dodge that will fit.if i am wrong about that im sure someone in here will know and tell you

out of all the jeeps in this town the d**n gremlin had to invade mine

I've done so much,with so little for so long i can practicly do anything with nothing
