65 comet

hey guys how hard would it be to put a 347 with tri-y's into a comet 404 as is stock with 289/302 its almost impossible to remove el headers with out comming out with bloody knuckles :screwy: i dont want to chop or weld

Hooker makes a header specifically for the Comet/Falcon which will work with your 302/347. Most of the Tri-Y headers are for the Mustang which has a little more room in the engine compartment. You may have to do a little massaging to use a Mustang header, but it should not be an extreme chop and weld.
That is the price of performance.
