Hi, right now I'm running an ofna lx2 with a force .28, I'm having some tuning and running issues, if i cant figure out how to get this to run right I may be in the market for a new engine. My question is, what's a good, torquey, and powerful BB engine that is comparable to what I already have, something that is plug n play, something that will fit and the existing clutch Bell and gear will fit the shaft. Not looking to spend a ton since I have no Interest in racing like I used to do years ago. Just let her rip when I take it out. Thanks
