I think it's crazy they put 3:42 gears in them and not 3:73 like the earlier years or newer ones

Hey man, what cut delivery valves would you recommend for performance on a stock 12 valve? Have only heard things about 191 but that they aren’t recommended on stock turbos, valve springs and governor springs

37/13.50 on stock 68 with 2g swap does fine

The entire point here is 5th and 6th gear are the weak points and at such a low rpm with bigger tires it’s not spinning the pump fast enough to keep line pressure up

I have a 14 2500 with 212000 miles stock 68 fluid changed every 20-25k miles and 35s with the 3.42s I won’t go up to 37s until I get a built trans lol

Gotta change that CCV filter more often. Always see leaks there when waiting til the service interval. Cut the interval in half and you'll have way fewer leaks.

Locked converter shifts on a 68 will make a 48 swap and manual swap look like mush

Aside from bypass I’m at 320k on my 68, granted it is getting tired and I’m 3.73 on 35s. They aren’t terrible it’s just like you said have a little practical thinking.

My last truck was on 37’s and 3.42’s. MY current 68 truck with 3.42 I wanna run 325/60r20’s but is even that to much tire? With trans tuning.

Should be swapping gears on any vehicle that you put drastically bigger tires on. That’s just common sense.
