@ the nqs pulls $500 to win and the flatheads can pull in 4 different classes. Every 2 years you do new rod, piston, valvestrain. Every 4 ya put a crank in it. $10,000 will get you a motor that can win anywhere. For the last two years at the national pulls I haven't finished out of the top 4 in points in 3 of the classes. Points pays $1,500 to win.
Motor prices are on their way down on both styles of engines cuz of competition. But just like anything, you're going to pay morefor the best. Some people choose to spend thousands on tractors, going around the world skiing, cars, whatever your pleasure. No one said you have to buy this motor lol. And if you can do stuff yourself...you can build a kohler twin for less than $2500.
