I finished the basic upgrade this weekend to a 1982 F-250 4x4, 300 l6!
The upgrade includes:
Offenhauser "C"intake
Holley 390 cfm carb
EFI exhaust manifolds
High flow cat and Flowmaster 40 muffler

This setup works great and the exhaust sounds great!
I am working on the emmisions systems!
The air system is easy but the EGR is harder!

 

5_labs, Thats great! When you going to put some pics in your gallery?I'm going to the mountains this weekend so I will be adding to mine.

Give me a couple of weeks, I am/will try to get all the information posted!
