Pistons and Pins: What’s New
Asking piston manufacturers “what’s new” reveals a number of trends that are reshaping the piston business today. One is that there’s no longer a time lag of three or four years for aftermarket piston suppliers to tool up for the latest piston applications. Production engine remanufacturers (PERs) and custom engine rebuilders (CERs) are asking for
Old Iron: Old Gaskets And Seals Won’t Stop Vintage Job Profits
It has been a long time, but I still remember – despite the snow on the roof. I had to go through a flathead Ford to try and seal it up and clean the engine for a restoration project. This was about 35 years ago. At the time I found fairly quickly that when it

Restoration – Yesterday’s Treasures, Tomorrow’s Trophies
There have been tremendous and significant changes in vehicle design since the first gasoline-powered vehicle hit the streets of America back in the early 1890s. Such advancements as fuel injection, radial tires, variable valve train technology, roller cams and front-wheel drive, among many others, have made cars easier to maintain, safer to drive and more
What’s Hot In Performance – Cams, Lifters & Rockers
The camshaft is really the heart of every performance engine because the cam defines the engine’s breathing potential, its torque curve and peak horsepower. The camshaft controls when the valves open, how quickly they open, how far they open (with some help from the rocker arms), how long the valves are held open, and when
Pera’s Core Corner
In the quest to find the latest and greatest information about different casting identification, oddities and interchangeability to assist those within the engine remanufacturing or rebuilding industry, it is easy to lose sight of valuable information from the past. No, I am not talking about the ’50s and ’60s, although that may be an idea,
Just Imports
So, you aren’t willing to work on import engines? To you they just seem too complicated and overwhelming? So you end up making the statement that you don’t do foreign vehicle repairs – or more specifically, import engine repairs. What happens when you get an offer to do a Mazda B2300 motor or work on
Rebuilding the Chevrolet LT1 Engine
Compared to the 1991 Chevy 350 L98 with TPI, the LT1 made 20 percent more horsepower, got better fuel mileage, and had a much broader torque band with 90 percent of its peak torque available from just over 1,000 rpm all the way up to nearly 6,000 rpm. GM Powertrain accomplished all of this by
Rebuilding the Chevrolet LT1 Engine
Although it shared many common dimensions, looked much the same and even had a few common parts, it was totally redesigned to provide more power with lower emissions and better fuel economy. Compared to the 1991 Chevy 350 L98 with TPI, the LT1 made 20% more horsepower, got better fuel mileage, and had a
Steering A Course Through The Rack Wars: Today’s Market For Remanufactured Rack-And-Pinion
Is today’s market for remanufactured rack-and-pinionsteering units meandering through the doldrums of a mature aftermarket,or is it heading in a new direction that may soon create new opportunitiesfor rebuilders? Some say the worst is behind them. They sayrack prices have bottomed out, competition has leveled off, anda growing number of retailers have come to realize
