My many thanks to Jimmy, Dodger and Steve. The tack problem solved, it was the switch on the back of the tack, got it in the proper position. I am turning as predicted 2850 RPM @ 70 MPH Think I am going an upgraded transmission to reduce top end RPM. 904 3sp/w overdrive. Leave the 3:23 rear end alone. Thanks to all...knowledge on this web site has shined again!
