Product Details

The COMP Cams 33-443-11 is an Xtreme Energy retro-fit hydraulic roller camshaft engineered for high-performance Big Block Ford 352–428 c.i. (1963–1977) applications. Designed for street and street/strip use where both throttle response and top-end horsepower are the priority, this camshaft takes advantage of the latest improvements in valvetrain components and developments in camshaft design.

The aggressive lobe profile produces better throttle response and top-end horsepower than other cams with the same duration at .050" lift, while delivering increased engine vacuum. It is designed to work well in high-performance street cars with 10:1 compression or higher, 3,000+ stall converters, performance intake, gears, and headers.

Camshaft Specifications:

  • Grind Number: XR294HR
  • Cam Type: Hydraulic Roller (Retro-Fit)
  • Advertised Intake Duration: 294° / Advertised Exhaust Duration: 300°
  • Duration at .050" Lift: 242° Intake / 248° Exhaust
  • Intake Valve Lift: 0.553" / Exhaust Valve Lift: 0.572"
  • Lobe Separation: 110°
  • RPM Operating Range: 2,800–6,100
  • Camshaft Material: Billet Steel
  • Gear Attachment: 1-Bolt
  • Valve Springs Required: Yes (upgraded springs required)

Important Installation Notes:

  • This camshaft requires an aftermarket bronze or composite distributor drive gear.
  • Use of stock valve train components is not recommended due to the aggressive lobe design.
  • Sold individually — camshaft only

Built on a billet steel core, the 33-443-11 is ideal for serious street and strip Big Block Ford builds seeking maximum power output in the 2,800–6,100 RPM range.

REALLY HARD ITEM TO FIND VERY SATISFIED

Awesome, cheapest one line,plan on doing more business. Thanku

you say you have the item in stock

thanks

Pretty nice website with more parts for my Supra than I thought!

The items that I was looking for were easy to find.

cheap prices

Good enough

Never used Autoplicity before but I sure do like the fact that it saved me from waiting 5 weeks on a back ordered item that I needed much sooner. Excellent service!

Fast and easy.

I was searching for brake rotors on the Internet for over 3 hours tring to find the best prices-- Autoplicity beat everyone hands down! The best deals out there. Quick response and my order shipped within one business day! Bravo. <br><br>Their website could be improved by auto selecting make/model combinations. I had to double check the part numbers for the pads..they matched the rear pads with the front rotors. I only caught this due to the fact that the pads were extremely cheap..too cheap. The low price was for the rear set as front pads usually at more expensive due to their larger size.

Excellent prices and fast shipping! Exhaust showed up as described and good to go! Very happy
