90 km/h normal speed or 55 MPH is at around 2.600 RPM.
I think that work in small rides say go on a hyw at 50-60 miles and go say 2.500 RPM.

Hank,

My rough mental math is calculating there is no way you'll be even close to 2,500 RPM @ 50-60 with 4.44's regardless of the transmission gearing.

I know you are really thinking about collecting all the right parts, but I believe you will regret that gearing choice. I'm pretty sure they were used in V8-60 cars because those cars couldn't get out of their own way and needed the gearing just to get moving.
