  • Application: Chevrolet Big Block 396, 402, 427, 454 engines
  • Designed for drag racing and maximum performance builds
  • Requires solid roller lifters, appropriate valve springs, and retainers (sold separately)
  • Best suited for engines with aftermarket cylinder heads and high-compression pistons

Performance Characteristics:

  • Aggressive lobe profiles for maximum lift and acceleration
  • Optimized for high-RPM power delivery

Professional installation and dyno tuning are strongly recommended to achieve optimal performance and reliability.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Easy to find and to pay with amazon.

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.

Easy order placement, fast shipment
