Product Details

The COMP Cams K11-423-8 Xtreme Energy K-Kit delivers everything needed for a complete camshaft upgrade on Chevrolet Big Block 396-454 engines. This hydraulic roller cam kit features a 224/230 duration profile designed to provide excellent mid-range torque and horsepower gains with a strong idle quality.

Complete K-Kit Includes:

  • Xtreme Energy hydraulic roller camshaft with 224/230 duration
  • Hydraulic roller lifters engineered for performance and durability
  • High-performance valve springs matched to cam profile
  • Premium valve spring retainers and locks
  • Valve stem seals for proper oil control
  • Timing chain set for precise valve timing

This K-Kit is ideal for street/strip applications where improved throttle response and increased power are desired.

It was quick and easy to place the order for my 1996 Pontiac Firebird. I would recommend & use your online ordering system again.

The wrong part for my truck ,i order this part because on your website it said it was for my truck and is not the right one

Very quick and easy

Good price, quick shipping.

excellent customer service

Best price and the shipping was not padded with invisible handling charges like you get with other vendors.

Great prices and quick shipping! They kept me informed of when the item was shipped also. Couldn't be happier!

Great prices. Great live customer service. Very pleased, will definitely order again.

Lowest prices I found on the net and great customer service! Fast shipping too!

GREAT SERVICE, FAST SHIPPING, WILL USE AGAIN

Nice and easy transaction!

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Best price around, very fast shipping and great service! I will buy from them again!
