Well let's not go running off and calling Jpar smart...lol.
First I did get rid of my seven and a quarter first thing because I had blown those up before. I got a eight and a quarter and ran that for quite some time. After I got the Stroker motor I felt I was going to break it so I sold it before it broke and then build the 8 and 3/4 and after 20 passes promptly broke it LOL then I did the Dana 60 and never look back.. needless to say there was some trial and error...
