If you are not seeking every last spec of HP from your motor than the burn the cheap paint off deal will work fine!
Since you did not state what CID motor you are talking about, nor its max rpm then in general 14 to 18 inches will do it and if the motor never really see's over for 6k RPM for more than 3 seconds on a run then a 18 inch lenght will sever you the best!
