Well I'm hoping the cam, timing chain, carb and intake wake this motor up.
So I'm leaning to the 3.73's. I want to order them this week. I don't want to big of gaps between gears.

Like I pointed out earlier, mine as a stock other than a straight up timing set from a pre-72 engine and knocking the flame arrester out of the tail pipe, pulled a total load of 16,120 lbs with just me in it and full tanks, add wife, two ChowChows and two small grandkids, probably another 450lbs or 16,570 all together just fine. I had a 3.55 gear and C6 at the time. Still running the 4180 and all emission stuff except blocked off EGR valve vacuum.

Sorry for being so needy.

Well, what I have done with mine is in this thread: https://www.ford-trucks.com/forums/1...n-86-f350.html
I went to EFI so I could run an E4OD and still keep my 3.55 gear. In third lockup I will have no slip and in 4th lockup I will be a 0.71 X 3.55 or 2.52. The engine I am building will be .040 over with an Edelbrock Performer cam, block decked to get me up around 9.2-9.5:1CR and converted to MAF sequential EFI. My goal is to see if I can get a bit better than 10mpg empty and the 8.5mpg towing the 5th wheel. I also do have a bit more air drag with the 5th wheel.

I guess it depends how steep your hills are, & how often you're below 70mph.

I also got a box with this stuff in it.
I like shiny things.

Very likely he did, most suppliers list "one size fits all" timing sets for the pre 88 460s. If you ask about the 68-71 set, they tell you it's the same. I would just get a late roller chain set rather than even mess with a Morse set ever again. BTW, they are straight up.

It's the same one I posted. One key way. No advance or retard. I called tech support at summit when I ordered to verify.
I asked about the cloyes one and the roller will get me 2hp. So the dude said just get the regular one.

I'm not looking at gaining 2hp in frictional loss from a roller, I'm looking at not having to replace the crap hivo in 60k.
4* of cam retard is probably worth 50 foot pounds and a whole hell of a lot of throttle response.

I'm willing to spend the $5. That's not the issue.
If you check the application on this one I posted it is 68-71.
With no advance or retard at the cam or crank.
