Well,,,,,,Now i can't make up my mind...I was set to build my boat motor 302 into a 347....I have the heads,,cam,,,,intake...Specs....heads:54cc 289...1.84///1.54,,,ported...cam [email protected] 512 lift 109 lobe..Ford motor sport rpm intake....All this will fit my 302 to 347 BUT......393 is looken good now...I could build the short block for less money than the 347 and have a stronger engine.....Will my cam and heads work on the 393???? OH and my 302 flywheel....I know my intake will not fit the 393......I only want 400 to 425hp and run on pump gas...The 393 will do that with ease.....Any help would be appreciated......Russ.......
