I have A 1991 with A 350 throttle body Ext cab long wheel base .... Was wondering what are some things I could do to spice things up A bit upgrades worth my money ?

 

what exactly are you looking for, 10 HP or 100? There are many options available it just depends on what you want to do. Is it a DD? 2wd or 4wd?

 

Bump timing a little, 4-5 degree's. Put an adjustable fuel psi regulator on with guage, put it up to 14psi. Get an air inlet tube off of a Astro van and put from air filter to the fender replacing the baffled box. They like cold air.

Thats the cheap weekend type stuff, but you could do a cam swap, and a custom chip etc... Port heads, port intake, shorty headers...
