will a 383 squeeze in a 73 duster?

it will fit no problem it fits alot better than a 440.just the use schumaker mounts or transdepot mounts.u can use b-body hp mainfolds or c-body hp or c-body non hp mainfolds.or the schumaker headers.u can only the tti headers if u have manual steering. check this article out.http://www.moparmusclemagazine.com/techarticles/mopp_0811_1967_barracuda_big_block_swap/index.html
