I spent last year sanding and painting my 89 F350, turned out awesome, now doing the interior. Next I want to do some mods to the EFI 460. Currently all stock, dual exhaust with a manual 5 speed. Great engine just need more power/torque to pull our trailer and gear. I'm thinking a set of headers to start. First question, short huggers or is it really worth the extra $ for long tri-y? I am also wondering if I can swap out the heads to some dove-c without too much trouble? Eventually i will pull and rebuild when my $ account gets rebuilt first. Thanks for any suggestions!
