I have the 351w

Very happy with my Engine Factory motor…I have the 351w also. Runs very strong and they did give me a warrenty when I bought mine in 2005. There is also another guy locally that has one and he is also very pleased. I have 3600 miles on mine.
Pm me if you have any particular questions.
