I will tell you one thing, the 305 is not more powerful than the Ct525. I am the one that has been doing the testing of the Ct525 for the UMSS up here in Minnesota. The Evolution 525 by Pace Performance has 580HP and really high torque that I can't remember right now. Last year I only ran it in the open form with the wing against the ASCS 360s and at the last race of the year the lap times of a Ct525 were very close to the ASCS motors that have a lot more HP and double the cost. The beauty of this motor is that with no modifications other than a different spacer under the carb it will be restricted down to the 305 motor levels and is now running in the 305 class at Knoxville in that configuration. This year we will be running this motor in the same car in the wing and non wing UMSS sprint series. For it to get down to the level of the SBC 360 motors of the UMSS non wing series we will be running a different MSD box and a rev limiter but no change in the spacer, so the only modification between running both classes will to be to swap the box and throw on the non wing front axle. The goal is to get it down to just under 400hp. If I want I will be able to run this motor in the non wing UMSS, 305 Knoxville, Winged UMSS, non wing HRA, and even USAC or WAR if I wanted to travel. 80 shows before you even have to think about a freshen and then a trade in program from Pace. I think if I were setting up a new non wing budget series I would either go with one of the following options - 305 racesaver, 604 crate, or the Ct525 with the Knoxville spacer. 604 crate is going to be the least expensive, followed by the Racesaver, and then the 525 when you are talking new motors. Other considerations would be if you want the option to use the motor in winged divisions and different classes where the 305 and 525 are going to have more options there. As far as starters, don't do it as it will cause nothing but headaches for the teams. Up here every team is required to have or to arrange a 4 wheeler to start them. 500cc and above wheelers can start all these.
