Rebuilding The Ford 4.6L

That’s good news for rebuilders, because most of them are in vehicles that are worth fixing when they need an engine, but there’s some bad news, too. Ford has made a lot of changes over the years, so building the right engine can be a challenge. In fact, if you include the front cover with

PERA’s Core Corner: Updating Your Understanding Of Chrysler’s NGC

Head and Block Resurfacing

Resurfacing cylinder heads and engine blocks is an essential aspect of engine building today, whether the work is being done by a production engine rebuilder, a high performance specialist or small custom shop. Bimetal engines, multi-layer steel (MLS) head gaskets and tighter assembly tolerances make accurate surfacing more critical than ever before. The key to

Cutting Edge Tooling – Superabrasives in the Shop

The need for faster production speeds and higher quality surface finishes has made superabrasives almost mandatory for most resurfacing, honing and grinding operations. What makes these materials so indispensable for engine building today? Their superior hardness is a major factor because it provides outstanding tool life that far exceeds conventional abrasives. A set of metal

PERA’s Core Corner, Fighting Truth Decay About Cavitation Damage

It’s amazing how something that may be damaging or corrosive in one circumstance can be of great value in another, like using extremely dangerous explosives to put out an oil well fire. This month we are going to talk about a similar action yet on a much smaller scale, microscopic actually, and it’s called “cavitation.”

High Performance Piston Rings and Cylinder Finishes

Today’s performance ring sets are thinner, lighter and more conformable than ever before. Thinner, low-tension rings reduce friction for more usable horsepower. Less weight reduces ring groove pound out. Narrower rings also allow tighter tolerances and less blowby. All very good things when you’re building a performance engine. But they also require rounder, straighter cylinder
