I have a Brand New Comp Cams XE284 hydraulic flat tappet camshaft 51-225-4 for a Pontiac, and a new set of Summit HT951 lifters. I did open the box to look at it, but it is brand new. I decided to go with the smaller XE274 in my 400 instead. It comes with all paperwork and Cam Card. $160 Shipped. I will only ship within the U.S., and I only accept PayPal for payment.
