This Complete Master Engine Rebuild Kit is designed for 1984–1990 Chevrolet and GMC 454 7.4L OHV V8 big block engines. Featuring hyper-eutectic dish-top pistons, premium moly rings, heavy-duty double roller timing set, camshaft, and hydraulic lifters, this kit is a true one-stop solution for restoring your engine to OEM or better quality.
Unlike cheap, no-name kits that often fail prematurely, Redline USA (Portland, OR) and Enginetech (Dallas, TX) supply only ISO, QS & TS-certified parts that undergo factory audits, pre-shipment inspections, and in-house testing. That’s why every rebuild kit is backed with our Lifetime Warranty when installed by a certified machinist.
