I am also not a stock racer but after reading this forum there are more important things than picking the correct car. You have to come up with at least 50 reasons why you will not participate at most events. Some popular reasons I read are- 1/8 mile isn't a real race, no heads up,no class,not enough tear downs,entry fee too high, payout too low, bad track, not enough contingency,no scales, no fuel check, no qualifying, no ladder, too early, too late, too hot, too cold, too many cheaters,too many new cars, too far away and anything to do with IHRA.
Once you find the 1 or 2 races per season that will fit your idea of a perfect race to attend, you can choose a car to fit that schedule.
