Take the website down. No more shop work, all they offer now are cams.

Almost speechless after the first ride. All I could say was Wow. After trying four other builds and having less then Impressive results I was recommend to give Dave Mackie a try. So I did. Went with 107 kit on my 03 Dyna with t5g cams.

Expert performance for all harleys. State of the art cylinder head work. Very knowledgeable. Great cam grinds and if your anywhere in the state they are worth the drive or shipping. Thank you Monty

I don’t give 5 star ratings unless it’s merited. My journey with Monty started with a blown motor, greneaded bottom end and bike I had just bought from down south.

I had my 103 punched to a 107 using their hemi pistons, Mackie cams and Mackie reworked heads. I also had them put a Baker race clutch in and am glad I did.
