HPBG: Don
In that discussion we hashed over the disparity in coefficients of expansion between cast iron and aluminum (that caused a revolution in head gaskets around the time of the Cadillac 4.1L). We discussed surface conditions and how that affects gaskets and scrub. We discussed gasket coatings and how they remain plastic while not scrubbing and
Cracked Cylinder Head Repair
It seems as if many cylinder heads are doomed to crack from the very start because of their lightweight construction and design. Aluminum overhead cam (OHC) heads, in particular, are often found to be warped as well as cracked. But so too are many pushrod cast iron heads. Cracks are often blamed as the cause
Gasket Surface Machining is Critical to Cylinder Head Repair
According to this representative, the relatively short production life of modern engines also shortens the time that an aftermarket gasket company needs to remedy application-specific cylinder head sealing problems. Another issue is that, if the company develops a superior gasket sealing design for specific applications, the engine might disappear from the market before the company’s

Cam Drives and Timing Components
Cam timing plays a huge role in an engine’s power curve. Advancing cam timing shifts the power curve more toward the lower rpm range, while retarding it moves the power curve higher up the rpm scale. If an engine is being built for a particular application (stock, street/strip, drag race, circle track, you-name-it), how the
Engine Builder Shop Solutions: October 2011
GM LS Engine Building Tips The GM “LS” engine format (GEN III and IV) is a replacement for the Chevy small block.

2011 Stroker Engine Guide: Unlocking LS Stroker Engine Potential
Modifying the LS for more power is as easy as falling off a log, to apoint, then some tough issues arise, especially if you are building ahigh-rpm race engine. But until you reach that point, the LS respondsnicely to boring and stroking, improved cylinder head flow and theyrespond especially well to power adders. The only

Lifter Bank Angles of a Chrysler ‘A’ Block
The angle of the lifter bore is changed to help straighten out thepushrod angle. The standard lifter angle on the “A” engine is 59degrees from vertical. This points the lifter away from the center ofthe block and angles the pushrod toward the outside. Most of the blocks and some highly modified versions of the “A”
Pro Stock Engine Technology
For a gearhead it’s always interesting to look at the upper echelons of motorsports to see what’s ticking under the hood. F1, Sprint Cup, and endurance cars are all fairly engaging from an engine perspective, but nothing tops drag racing for its sheer power, variety and ingenuity. In a single event you have vehicles competing
Tips for Hotter Street & Strip Performance
Long’s HO Enterprises Performance Auto (www.hoenterprisesclassics.com) in Birnamwood, WI, sells hot rod parts, but his once traditional view on performance is changing as he sees his sons working on late-model imported cars with port fuel injection and “coffee can” exhausts. “Yeah, I think it’s all electronics now, but at least they’re car guys” Long points
Communication Breakdown: Diagnosing Engine Bearing Failure
Engine builders turn into medical examiners when this happens; getting the story behind the story is what you must do to understand what went wrong and what to do to avoid it in the future. According to engine bearing experts, a failed bearing is not usually the fault of the bearing but rather the fault
2011 Machine Shop Market Profile – Part 1
For what seems like an eternity, it has almost become commonplace to wait for the eye roll, the shake of the head and the hangdog expression before hearing the familiar refrain, “Oh, man, let me tell you…” In the engine building business, of course, the standard response industry-wide has, for many years, been simple:?Lousy. Numbers
Three Reasons to Wear a Coat
What’s not usually as well known is the incredible versatility that coatings have in dealing with a huge range of problems. The number of uses for various coatings in performance applications is mind-boggling and nearly limitless, but in order to keep the possibilities cost effective and manageable it’s useful to think about it in terms
Ford 4.6L SOHC Labor Cost Study

Oiling Systems For Grassroots Racing
One of the first things to look at when building an engine is the oiling system. Dry sump systems are very scalable and efficient but are not known to be inexpensive by any means. Wet sump systems, on the other hand, offer affordability and can handle some impressive performance applications, but using all stock components
Sprint Car Engines: The Current State-of-the-Art
Sprint Cars are just about the fastest machines in racing, often running two or three seconds faster per lap than late model stock cars. There’s no time to just tool around in this form of racing, no pit stops, and it’s over before you know it. Everything is to the limit with engines pushing between
