I love this thread. Iam getting ready to purchase a 470 low deck kit and its good to see the pros and cons of the source kits. Iam sure none of them are "drop it in and go racing" kits but iam learning alot about what to look for and checking everything 5 times. Iam a budget minded racer and was leaning towards the source kits but the more i read,the muscle motors kit is looking better and better. Thanks for all the info.
