Zach....you look like you keep records of your mpg like I do....good stuff there. Is your truck tuned to offset the odometer being off as well?

Also guys, would it be better to get the heads and use a slightly bigger cam like the 212/218 high lift?

 

If you are trying to do this cheap, forget about heads. Get the 212/218, tb stall, and a good tune and you will be fine.

 

I don't remember if it was changed back then or not.. hrmm

 

Anybody with real numbers (dyno/track times) after doing this swap with heads and cam?
