The Cobra Automotive Road Race Engine starts with a Dart block that is specially CNC-lightened using our own proprietary program. We then bore the cam tunnel for 55 mm rollerized cam bearings and the entire inside of the block is deburred. We use only the best custom-forged racing crankshafts, made especially for road racing, and smaller low-friction Honda rod pins, while retaining the standard small block Ford main bearing diameters and widths. Custom steel billet Oliver connecting rods are mated with JE dome pistons using special tight-tolerance stainless steel rings. Our cylinder head CNC porting program is very aggressive, and we finish off the porting operation with a thorough hand polishing to assure we get every last CFM of airflow from the intake and exhaust ports. Jesel split-ratio Pro Series shaft-mounted rockers finish the valve train to keep the engine pulling hard all the way to its 8500 rpm redline. We have both dual and single plane intake manifolds available for these engines, featuring more porting than anyone can imagine. On an engine this sophisticated, the stainless steel “stepped” headers are an absolute must if you want to squeeze every last bit of horsepower out of this engine and stay in front of the competition. Every Cobra Automotive Road Race Engine is built with the latest technology in wet sump oiling, including specially modified oil pumps and custom-built aluminum oil pans. Naturally, we use only the best ARP hardware and Race Series Fel-Pro gaskets. In full competition trim, this engine generates 580 horsepower. Call (203) 284-3863 for pricing.
