Since Boss 302 crate motors don't seem to exist anymore and the Boss 302 Road Runner motors seem to have a reputation for popping when driven hard, I'm thinking of detuning the motor in my Boss 302S to increase the odds that this motor survives for at least 5 years. It's a race car and will be raced in regional vintage races just for fun and run at the occasional time trial and track day. I won't be doing any serious racing with this car. I just want to have fun with it and keep the cost of ownership reasonable. By detuning, I mean running the motor a bit richer and also lower the redline from 7500 to 7000 rpm. Basically, sacrificing performance for durability. What are your thoughts on this and is there anything else I can do to increase the life span of the engine (and the rest of the car) while still putting it on a race track?
