434 ALL Cleveland
“HR” Silver Acc. Plus Engine 690+ HP
(Dynoed With Turn Key Extras)
This high-performance engine package features a heavy-duty aftermarket Aeroflow block paired with our in-house CNC-ported CHI cylinder heads. Externally identical to an OEM Ford Cleveland, it is a true bolt-in replacement while delivering significantly greater strength, reliability, power and torque.
Built with a hydraulic roller camshaft, the engine requires zero tappet adjustments for the life of the build. Internally, it’s fitted with a forged steel crankshaft internally balanced, forged pistons and Scat H-beam connecting rods. The result is an engine that produces outstanding power and torque with serious long-term reliability and virtually maintenance-free operation.
Whilst the highest factory Ford Cleveland — the legendary 1971 Boss 351 — was rated at 330 hp, this package delivers double the power plus at 690+ hp.
Please note: This engine does not fit under a standard bonnet. A reverse cowl scoop or raised bonnet is required for.
