Well, there are several schools of thought on "being competitive". On the one hand, if your looking for and engine the will be faster or as fast as your competition, OPS is not it. I have run OPS for years and there are others that are alot faster then me. I run them because I know them and can finish races. Thats the other school of thought, you can not win if you do not finish the race. My advice to you is to run what your friends are running so you can share information about set up. It also comes in handy to know that if you need a part at the race site, one of your buds might have it, if you have the same engine. OPS engines are also less expensive then other engines. I have friends that run CMB at $500.00 a pop. If you have the cash, I think CMB is one of the fastest most competitive engines on the market. OPS is a good consistant engine that will not break the bank. But it will not be the fastest.
