Re: signature engine
I called Coan and talked to them about a convertor. I am running a 2500 stall. I also replaced the R&P to a 389. I had a 513 gear in it with my small block. Now I can cruise on the interstate a 3000 rpm @ 75/80 mph. Before I was going about 60/65 mph. I also have a 33 inch tall rear tire.
The convetor was $877.50
I had a 3500 ATI convertor ( $350.00 ) behind the 406 but after talking to Coan and a few friends with blower motors I went with the Coan convertor. I believe the ATI would not of lasted behind the torque of a blower motor.
