The LA series of engines were 318/340/360 and later MOPAR engines up 2003 including the V-10.The 318 is possibly the most trouble FREE engine EVER to come out of Detroit. How ever , it isn't exactly a "stop-light warrior.Headers,manifold and a good carb(maybe a cam)it'll be fun enough for you in a Scamp.What gears are in it?The tranny should be a 904-rare possibility of it being a 727.
