The new cylinder block is made from a modern grey iron alloy as used in current production engines. The exterior is identical to an original cylinder block through the use of laser scanning. Ford drawing A-6015 was used to ensure that all surfaces and hole locations are identical to an original cylinder block so that original or new aftermarket parts can be used in the build process. The interior is similar to a modern engine with 5 replaceable main and camshaft bearings, 16 pressure lubricated bearings, 2-inch diameter main bearings, large, streamlined intake ports, hard exhaust valve seats, and an off-the-shelf radial lip rear main seal.
The new Crankshaft has 8 counterweights with 5 main journals and weighs 55 lbs. It is cross-drilled to lubricate the 4 connecting rod journals, and is dynamically balanced. The front and rear interface surfaces accept the standard timing gear, front pulley, and flywheel original to the Model A engine. The main and connecting rod journals both utilize the same standard 2" insert bearings that are commonly available.
The new connecting rods are forged steel and utilize 2-inch diameter insert bearings. Wrist pin bushings are installed and ready for assembly with standard Model A type pistons. The connecting rods are balanced in sets of 4 and the rod caps are bolted in place with UNF 3/8-24 170 KSI, 12-point bolts.
Optionally available is the newly designed, lightened, and balanced 31 lb. flywheel. The mating interfaces to the crankshaft, pilot bearing, and ring gear are identical to an original Model A flywheel. Our flywheel is drilled to accept the V-8 9-inch Long design pressure plate. (pilot bearing and ring gear are not included).
The new camshaft has .340 inch lift and the lobes are separated by 113 degrees. It is made of nodular iron which is the material of choice and used in nearly all new engines. Lobes are induction hardened to HRC 58/62 to minimize wear, and the 5 bearings and center gear is hardened to HRC40/52 to keep the gear teeth from becoming brittle. Ford drawing A-6250 was used for all interfacing dimensions and if the new camshaft is used with our "New Engine Kit", there will be 17 pressure fed bearings instead of 16. The new camshaft can also be used in all Model A, Model B, Russian GAZ, and German G28T engines.
This newly manufactured Model A cylinder head is identical in appearance to the original heads manufactured by Ford for the Model A engine. It has a 6.5:1 compression ratio and improved coolant circulation openings to maximize even cooling from front to back. It is manufactured with modern grade cast iron and is dimensionally accurate.
