RE: fastest small block under 250$
well, for an xxx-nt, i think we could all agree that a .12 would be the best choice for any racing purpose. there's the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXJFY8&P=0]O.S. .12 tz(p) 3 port[/link], as well as the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXJFY9&P=0]5 port[/link] version that is a little faster. there's also the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXSNB8&P=0]picco Jrl[/link] which is only 179.99 and is a great motor.
