Product Details

The COMP Cams 08-303-8 Nitrous HP hydraulic roller camshaft is specifically designed for small block Chevrolet engines equipped with factory roller blocks and nitrous oxide systems. This performance camshaft delivers aggressive power characteristics optimized for nitrous-assisted applications while maintaining streetability.

Camshaft Specifications:

  • Advertised Duration: 236° intake / 248° exhaust
  • Duration at .050": 218° intake / 230° exhaust
  • Valve Lift: .470" intake / .488" exhaust (with 1.5 rocker ratio)
  • Lobe Separation Angle: 114°
  • Hydraulic roller design for OE roller small block Chevy applications
  • Optimized grind profile for nitrous oxide injection systems

Key Features:

  • Designed to work with factory roller lifters and blocks (1987-up SBC)
  • Aggressive profile provides excellent power gains when combined with nitrous
  • Hydraulic roller design eliminates the need for break-in procedures
  • Maintains good vacuum for street driving and power brakes
  • Ideal RPM range: 1,500-6,000 RPM
  • Works well in 305-400+ cubic inch small block Chevy engines

This camshaft is an excellent choice for street/strip vehicles with nitrous systems, offering strong mid-range to top-end power while remaining streetable. Requires matching hydraulic roller lifters, compatible valve springs, and proper pushrod length verification for your specific application.

Ordered an Fabtech steering box skidplate, best price I could find on the net was Autoplicity. Price was better than all the 4x4 sites I checked. Item is shipping directly from Mfg, so really can't comment on shipping speed. Otherwise, transaction was easy and I really like the fact they accept PayPal.

easy

very good, for my first time .

First time buyer, so far has been very satisfied. However, the real test would be if I need autoplicity for customer service as needed.

Awesome pricing. Needed Pertonix setup for my wifes 62 Mercury Monterey Convertible S-55.

Ordered A K&N Filter For My Bike. The Price Was The Cheapest On The Web. It Shipped Right Away. Very Happy

Very simple & fast.

Great product and was the cheapest I could find. Easy to order and shipping information e-mailed to me the next day.

Crazy fast shipping. By far the best price of anywhere. The thule bike rack we ordered was in stock, lowest price, easy checkout process, and the company really appears to run an organized, professional business. Very happy with the level of service. We will definitely make sure to use autoplicity in the future.

good

Good buy , no problem!

Wow, cheapest price I could find anywhere. AND, it shipped the same day. Amazing service. Thanks Autoplicity!

Autoplicity IT help desk was great in getting the order done. I had problems with my computer and the IT person worked things out so the order could be processed.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!
