I have a 1989 F-350 w/ non turbo 7.3 I can't find any aftermarkets for it is there any valve adjustments or pump tweeks that I can do to hop it up a lil and make it blow some smoke out the 6" stacks and pull harder?

 

Just read about what everyone has to say here, there's all kinds of things you can do. Also check out ATS(http://www.atsdiesel.com/ats_new/pro....asp?y=3164703) they've got a bunch for these things

 

these guys seem to know the idi engines better than anyone I have seen 6.9L IH & 7.3L IDI Diesels - Oilburners.net

 

Check out Hypermax. They specialize in Ford performance, they have lots of IDI stuff. They have a turbo kit, intercooler kit, rods, pistons, ETC......
I think there web site is Hypermax -Ford Power Stroke Diesel Performance Ford Diesel Power, 5"exhaust, Mach 7, power chip, injectors, intercoolers, turbochargers
For tweeks, you can turn up the pump, do exhaust, ram air intake, advance the timing by about 5 degrees. Its the small things that count.
I straight piped my truck with 4 inch to 5 inch stacks and dual 4 inch intake pipes into the air cleaner, advanced timing 5degrees and installed a K&N Much Much better. The biggest increase i found came from the exhaust.
But just wait more people will let u know about some other stuff to do.

As far as i know i dont believe there is cause this engine uses hydralic lifters.

 

yes, these engine use hydro lifters, so no valve adjustment.


since another site was listed above, and i hope i dont get yelled at, but i learned everything i know about them from the diesel stop. it is a ford only site. i figured i would come over here and help out.
