Product Details

The COMP Cams 34-337-4 Magnum camshaft is a hydraulic flat tappet camshaft designed specifically for Ford 429 and 460 cubic inch big block engines. This camshaft delivers a balanced combination of mid-range torque and top-end power, making it ideal for street performance, marine, and RV applications where reliable low-end grunt and strong acceleration are priorities.

Key Specifications:

  • Advertised Duration: 253 degrees intake and exhaust
  • Hydraulic flat tappet design for quiet operation and easy maintenance
  • Magnum series grind optimized for street and marine use
  • Compatible with factory valve springs and components in most applications
  • Requires standard small block Ford firing order modification for 429/460 engines

Performance Characteristics:

  • Strong mid-range torque for excellent throttle response
  • Smooth idle quality suitable for daily driving and marine applications
  • Works well with stock or mildly modified cylinder heads
  • Ideal RPM range: 1,500-5,000 RPM
  • Recommended for engines with stock to 9.5:1 compression ratio

This camshaft is an excellent choice for builders looking to wake up a tired 429 or 460 Ford big block without sacrificing reliability or drivability. The hydraulic flat tappet design eliminates the need for valve lash adjustments and provides quiet, maintenance-free operation. COMP Cams manufactures this camshaft from premium materials with strict quality control to ensure precise lobe profiles and long service life.

this is my new home... very cool site, beat summit and jegs by $20 to $30

Great customer service. Fast order processing. Hassle free transaction.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

Thanx

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!
