product just as described, received in 3 days

the order was quick and inexpensive. I would have bought a carb if I could have found an Edlebrock I am not a holley fan sorry.

Super Fast! Website was easy to user, multiple different payment options (Amazon, Paypal, Credit Card) Got a notification of shipment within 1 hour!

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
