- Description
Description
Stroker kit that converts the 3.8L McLaren M838 engine (570, 650, 675) to the 4.0L specification found in the 720, 765 and 750, increasing displacement, power and throttle response while handling higher loads. Everything needed for the conversion is included.
Included
- Billet crankshaft (standard 720 stroke)
- Custom Magnus sleeves, pistons, and billet 4340 connecting rods and pins
- Friction washer, piston rings, main bearings, thrust bearings and rod bearings
- Main bolts, head studs and all required gaskets
The rod-guided piston design keeps the piston square in the bore and square to the crank, correcting the bent-rod failures these engines suffer at high torque. The internals are estimated from experience to be good for over 2000 hp. Contact us to purchase.
