For me, I wouldn’t change anything. That .072 OD on that box with your tire size will give you about 2800 rpm at 75 MPH. If 2800 rpm is too high for you, you can drop down to a 3.91 and at 75 MPH you’ll be at a bit over 2600 so you’d gain a couple hundred rpm.

Im usually no more than a couple of weeks out. The exception is going to be when my engine goes on the pump. It will stay on there as long as it takes for me to flog its guts out.

I can’t imagine it would take me more than three days to break in the cam, install the inner springs, retorque the heads and finish the break in and then break in the pistons.

After that it will be sorting out the timing curve, tuning the carbs, adjusting the headers and lash loops. If all that goes well it will be about three days.

I try not to get myself buried because physically I can’t do it.

I'm good with 2600-2800 rpms at 75 mph and since the 4.11s are in there already, I'll leave them - one less thing to check off the list. On the engine side, the block & rotating assembly are back from the machine shop, cleaned up and ready to go together. I'm waiting on a rear main seal block and a distributor. Both are coming from a private source and shold be here by Thanksgiving. I spoke with A&A Trans this past week and they are shipping the cross ram hardware and fuel lines so that should be the absolute last parts needed to complete the engine. Next on the list is to fabricate some air bells ($600 is too dear for 2 of those! Holy highway robbery Batman!) and screens for the carbs.
