have just finished a ft eng dragster, passed tech 1st time to 7.50. morrison has plans , get them, a nhra rule book, and the sfi specs. The best deal is buy one running, or roller. a friend sold his 4 yr old back motor, complete and the guy stoped off at a track on the way home and won 2 k. you can buy used cheaper than build. try racing junk. com. lots of bargains.
