6.4/8hp70 finally up and running and ready

I'm surprised a flat hood fit.

So they got the 8HP to work using the old shifter? Or is the new shifter hidden under there? Any details?

Very cool. I've always thought the 8HP would be perfect for a drag and drive event.

The stock tire diameter on an SP is like 28.7", so if your tire is shorter than that you might be very close to the stock 3.06 ratio the Scat Pack runs. And you are probably 600+ lbs lighter.

I like it. I bet it runs hard and cruises nice.
I can't speak for the 8H, but on the 545RFE, the number of detents is same as a three speed. There aren't detents for the o.d. positions. I've done a couple of trucks, a 62 and 78. The 78 utilized the factory column shift. The 62 utilized the dash mounted cable shift.
