  1. What is the largest tire I can fit in the back W/out any modifications? Thanks.
  2. Just getting my 400 running again. Any idea how much hp/tq it will pick up with a little bigger cam and 850cfm carb?
  3. So I had to rebuild my 400. in doing so I put in a new cam with a duration of 298/303 and a lift of .466/.488 and an edelbrock carburetor with 850cfm. How much hp/tq do you think this will add?
