Ross Racing Engines’ Tony Lombardi cut the valve reliefs using an end mill and his adjustable piston vise. Build, text and photos by Mike Mavrigian The Pontiac bigblock build (starting with a 455 block and boring/stroking to 501 CID) is progressing. I apologize for the time delay, but this build has been [...]
MAHLE Clevite Inc. introduced 62 new part numbers in November for various types of bearings, cylinder components, filters, gaskets, piston rings and turbochargers. The part numbers are available for a range of light vehicle and heavy duty applications.
Build, text and photos by Mike Mavrigian . I realize it’s been a while since my last posting of this project’s Part 1 article, but I’ve been tied up with multiple projects at the same time. Since the Part 1 article, I’ve obtained the crankshaft, had the heads finish-machined and assembled [...]
Diamond has announced new premium forged pistons with tool steel piston pins for turbocharged small-block Chevrolet engines. Especially suitable for drag racing applications, this new piston is produced in 2618 aluminum and is designed to fit most 23-degree cylinder heads.

I’ve decided to have the water pumps and pulleys polished and chrome plated. This will provide additional visual appeal. Engine build, text and photos by Mike Mavrigian In this series installment, I’ll discuss final installation of the rods and pistons, the oil pump and pan, timing cover, water pumps and cylinder heads.
Conclusive data shows that DLC coatings (diamond-like carbon) extend the life of piston pins by a factor of four or more—virtually eliminating pin-bore troubles. Coated pins in Pro Stock drag cars now last 32 miles instead of 8 and Cup cars, whose uncoated pins could barely complete a race without sustaining piston pin galling [...]
She’s done. In this article, we’ll cover crankshaft balancing, valvetrain and crankshaft assembly. How do you like the plug wire routing? I’ll cover this in a later article installment. I’m considering having the water pump pulleys polished and chrome plated. By the way, the water pump/alternator belt pulley alignment is perfect. If the belt looks [...]
