This truck is powered by the mighty 250 inline six. What? Did you say 250? Isn't that supposed to be a 230? Nope. This truck was built in LATE '65. 66 was the first year for the 250. Don't believe me? Look up the engine code suffix. Suffix TF. Maybe it was swapped out at some point but, given this trucks history of owners, I don't think so.
To get the highway revs down, I needed to get the 3.73's OUT. So I do'd dit.
Enter 3.08's and a GOV LOCK... Had 'em laying around, why not. Set up the new-used gears to perfection. Much better. If I tear up a GOV LOCK with my mean buzzin' half dozen, I will only laugh.
It's gonna be sweet!
