overdrive help
I have decided to go with a Mitchell overdrive in my 37. Engine is in good health but it is a 21 stud 85hp stock engine. After doing the math I have calculated my rear end gear must be a 4.10 ratio. The rear tires are 29" tall. I am running just shy of 3000 rpm at 60. (about 2900)
My question is, and I appreciate any feedback.. Even though my cabriolet is a fairly light car, will my engine be enough for a 36% overdrive? That is what I ordered but I am thinking I may need to change my order to a 26% unit. Any feedback from anyone running a similar set up as far as stock engine and overdrive would be very helpful. Thanks in advance. All input appreciated.
