  • Xtreme Energy 250/256 hydraulic flat tappet camshaft
  • Hydraulic lifter set (16 lifters)

The Xtreme Energy camshaft line is engineered for street performance vehicles where improved power and responsiveness are desired without sacrificing drivability. This profile works well with stock or mildly modified cylinder heads and provides a noticeable performance gain over stock camshafts. Ideal for street machines, muscle car restorations, and weekend cruisers running pump gas.

Application: Oldsmobile 260, 307, 330, 350, 403, 425, and 455 cubic inch V8 engines. Compatible with factory hydraulic lifter bores and stock valve train geometry.

COMP Cams is a leading manufacturer of performance camshafts and valve train components, with decades of engineering experience and proven results on the street and track. Each camshaft is manufactured to strict tolerances for reliable performance and long service life.

Great site. I received my product quickly and it was the product I ordered.

Good company to deal with, will gladly do business here again.

Ordered MSD window switch. Best price on the internet and received package within 3 days of ordering. Great place to do business.

I've thought about this...Better communication would be a plus. However, the shipping is quick and I did get an email telling me my product was shipped. I purchased window visors for my '07 Silverado. I will do business with Autoplicity again.

The Curt Class III Hitch Receiver installation on my vehicle was simple and easy. The hitch is of good quality. I would recommend this product. Autoplicity was prompt with the order process and delivery.
