• What engines is this kit compatible with? It fits all Mark IV, Gen 5, and Gen 6* Big Block Chevy engines (standard or tall deck) ranging from 366 to 572 cubic inches.

*Gen 5 and Gen 6 harmonic balancer require a different crank pulley adapter. Call to have this switched out at no extra charge.

• Does this kit clear tall valve covers? Yes, the brackets are designed to provide clearance for tall valve covers, making them ideal for high-performance builds.
• Why does this kit use a Type-2 power steering pump? The Type-2 pump (remote reservoir style) is more compact than P-series pumps, allowing the alternator and pump to be tucked in tight for maximum steering box clearance.
