Rsbootz Posted July 25, 2017 Share Posted July 25, 2017 I'm trying to get information on how to turn my 1981 Mack semi up. I'm using it for tuck pulls only so it doesn't have to be Road Legal but I just don't know anything about Mack motors any suggestions?

Before you do anything find someone that can work on it if you don't know anything. It is going to cost you and Good work requires Good pay. It is not hard to turn anything up to a point but parts will be braking and there is always something to fix or make better. Big parts cost big money as well then modifying them to work is an art in itself. Guys that don't know anything in any type of racing don't last long or need a lot on money to have someone that does know. Even if you are just doing a street class and expect to place or win, the competitors trucks have modifications, good luck, which is part of racing as well.
