Performance mods for a 1990 F-250

Drive under an overhead hoist and lift up the antenna. Slide a Chevy underneath it and lower antenna back onto the truck. You're done.

You may have gotten into the wrong group by accident. This is a Chevy group.

Other than that, it sounds like you've got your bases covered. Maybe change the gear ratio if you're looking for low end or for towing.

mazda 5-speed overdrive tranny. It, obviously, is a little underpowered especially when passing at 65-75 mph (2,250-2,750 rpm) i am going to fix the exhaust next, it has stock manifolds, two catalytic converters, and a glasspack, ew! I am also looking into, chips, new ignition components(like msd) and possibly even a supercharger or twin turbos. if you want to warn me about anything i mentioned or tell me about something that might work better, please do, thanks.

You do realize this is a CHEVY newsgroup, right?

The wrecker attached to the front should improve gas mileage considerably

good engine. Tall deck?

What did you use for an intake manifold?

a kick-ass chevy, a 1974 burban, w/a 427 5-ton dump truck engine, i even bedlinered the whole truck. But i was being towed by ford's like twice a month, so i bought one and i've been towing chevy's ever since. (oh yeah, the fuel mileage also sucked, like 6-8mpg)

ok, ok, i moved it to ford's side, you guys are brutal. btw, i used to own a kick-ass chevy, a 1974 burban, w/a 427 5-ton dump truck engine, i even bedlinered the whole truck.

I don't know anything for your truck, but *I* don't mind you telling me what you've done once you've done it! Post links to pix when things come along! It'll never be as good as your chevy *could* have been - but it's not crappinese!
