Engine Internals

Engine Internals covers the parts inside and on the long block: camshafts, connecting rods and rod bolts, valve springs and valve seats, cam bearings and crankshaft seals, main girdle stud kits, valve covers, and the sealants used to assemble them. Edelbrock and PRW supply most of it, with Carrillo, GSC Power Division, Supertech and Proform for specific jobs.

These parts are bought by engine, not by body style. A part made for one engine fits every car or truck that used it, which is why a single listing can show fitment for the Chevrolet Impala, Chevrolet Camaro, Chevrolet Corvette and Chevrolet Monte Carlo at once. Ford Mustang and Ford F-250 fitments are common too. Start from the engine code and displacement, then confirm the vehicle on the product page.

Build in matched groups. A camshaft sets the lift and rate the valve springs have to control, and some GSC Power Division billet cams state that they require a spring upgrade; Supertech valve spring kits cover that job. Carrillo sells connecting rods in sets and rod bolts singly, so check the quantity in the listing before ordering. PRW main girdle stud kits are listed by part number, so match the kit to the girdle you run.

Some items are consumables that any rebuild draws on, such as Edelbrock high-temperature RTV silicone sealant and seals. Others finish the engine off, such as Proform die-cast valve covers in a tall style with a milled bowtie logo.

Where a part is vehicle-specific, the product page lists the years, makes and models it fits, and the vehicle selector shows only parts for your car or truck. Related: Edelbrock, timing components and the wider engine and driveline department. Priced in Canadian dollars, shipped across Canada.
