Chevrolet 396-454 c.i. 8 Cylinder (1967-1996)

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

I searched for a quality automobile battery charger and found the best priced and longest warranty "smart" charger at Autoplicity and one other seller. Autoplicity carried a wider selection of the models offered by the manufacturer.<br> Looking over the website I entered my vehicles into the fields and found quality offerings. It is worth looking at.<br> Ordering was straight forward, shipping began the next day with a tracking number, and the order arrived on time. I bookmarked the website.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
