Product Details

The COMP Cams K34-250-4 Xtreme Energy K-Kit is a complete camshaft upgrade package designed specifically for Ford 429 and 460 cubic inch big-block engines. This comprehensive kit delivers increased mid-range power and throttle response with a performance-oriented 240°/246° duration profile, making it ideal for street/strip applications and vehicles with headers, intake manifolds, and other bolt-on modifications.

Complete K-Kit Includes Everything You Need:

  • Xtreme Energy hydraulic flat tappet camshaft with 240°/246° advertised duration
  • Hydraulic flat tappet lifters engineered to match the cam profile
  • High-performance valve springs designed for the increased lift and duration
  • Precision-machined steel retainers
  • Valve locks (keepers) for secure valve train operation
  • Valve stem seals to prevent oil consumption
  • Timing chain set for accurate valve timing
  • Assembly lube to protect components during initial break-in
  • COMP Cams decals and detailed installation instructions

The Xtreme Energy series from COMP Cams features aggressive lobe profiles optimized for maximum performance while maintaining excellent street manners. This camshaft typically produces a noticeable performance idle and significantly improved power delivery from 2,000 to 6,000 RPM. The K-Kit format ensures all valve train components are perfectly matched and tested together, eliminating compatibility concerns and providing everything required for a successful camshaft installation in one convenient package.

Applications: Ford 429, 460 cubic inch big-block V8 engines

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Great

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
