UPDATE:  4-4-17 PM

I put another 20 miles on the engine today.  I tach'd it up to 5,000 RPMs 3 or 4 times :yikes:  I seems to have plenty of torque in 5th gear @ 2,000 RPM = about 53 MPH.

The vibration seems to be tires – crap!

It still doesn’t start from a cold start as quickly as it should… I will be doing some diags and fine tuning Thursday.

If this engine (with the 261C cam) produces the torque numbers at the RPMs as indicated on my Engine Analyzer software, it will be exactly where I want my torque range to be for 80 MPH in both 5th and 4th gears – with my stock 4.10 ring & pinion and 31” tires!!

For example, if I’m cruising down the freeway in 5th gear @ 80 MPH - the engine will be producing 152 lbs of torque at 3022 RPMs, which is the beginning of its predicted peak torque range.

If I start up a steep uphill climb, and I have to shift down to 4th gear, the RPMs about 3555, which is the end of the peak torque range, about 151 lbs of torque @ 80 MPH.  This engine should be perfectly happy at 3500 to 3600 RPM all day long.
