Three-Keyway Crank Sprocket Installation
The camshaft angle is half of the crankshaft angle, therefore the camshaft will correspondingly advance or retard by ± 2°. By changing the cam timing, enhancements to the camshaft characteristics can be achieved. For example, retarding the cam timing will increase high rpm horsepower, and advancing the cam timing will increase low-end torque. The following
“The Technology Behind the Multi-Lobe Camshaft” Seminar Announced for PRI
On Friday, November 30, COMP Valve Train Engineering Group Leader Billy Godbold will host a free seminar entitled "The Technology Behind The Multi-Lobe Camshaft." Fresh off their win in the "Best Performance: Street Product" category at the 2012 SEMA Show, COMP Cams 4-Pattern Camshafts will be featured at the PRI Trade Show in Orlando, FL.
Camshaft Selection
When it comes to racing, sometimes the belief is that only custom-designed parts are good enough for a winning team. The question here is, do off-the-shelf components automatically have a performance handicap? In order to get to the bottom of the “Custom Grinds vs Catalog Specs” debate Engine Builder magazine reached out to experts at
Engine Blueprinting Basics
The top professional divisions in racing today for the most part run engines that are built to comply with a very strict set of rules for each series. In NASCAR, where the engines have been roughly the same 358 cid V8 for decades, the power output has steadily increased. Engines of the same brand that
New Product Award Winners From SEMA
The Specialty Equipment Market Association, has announced the winners of the New Products Showcase Awards held at the 2012 SEMA Show. The awards were selected by a panel of judges based on their superiority of innovation, technical achievement, quality and workmanship, consumer appeal and marketability. We have highlighted the product winners and runners up in the
Breakin-In Is Hard To Do
Before we begin discussing assembly lubes and break-in oils, I would like to emphasize that no one factor is responsible for racing success (or failure). It’s like an algebraic equation with a lot of variables, all of which must be addressed. The same is true of engine assembly and break-in. You must utilize only those
Crack Detection and Correction
First off, let’s get one thing perfectly clear – there’s no such thing as “flawless.” Like those shocking tabloid photos of that Hollywood actress who gets blindsided beside a bistro, even the most conscientious engine builder sometimes has to deal with surprising surface imperfections. And just as she has paparazzi to expose the damage and
Crane Cams Receives 2012 Florida Companies to Watch Award
Florida Companies to Watch is an awards program that celebrates privately held second-stage companies headquartered in the state. To be eligible, applicants must employ between 6 and 99 full-time equivalent employees and have between $750,000 and $50 million in annual revenue or working capital in place. Award winners are selected for demonstrating the intent and
Revised Timing Belt and Tensioner Setup Procedure for 1998-2000 Ford 2.0L Engines
During a timing belt servicing, refer to the following service procedure for details. Note: To achieve proper timing belt tension, the camshaft sprocketbolts should be loosened enough to permit the sprockets to turn freelyon the camshafts. With cam sprocket bolts loosened and cylinder #1 attop dead center (TDC), crankshaft must be rotated to TDC in
Muscle Car Engines: What’s Old Is New. And The Greates Of All Time
Baby boomers wanted to go fast even if they were just driving to the grocery store. The open road was calling and America answered. But the government intervened and quickly started killing the culture in the early to mid-’70s. Then the gas crisis of the late ’70s put the final nail in the coffin. Or
Preventing Camshaft Seizure on 1990-
The small hole in this restrictor may become partially blocked and limit the amount of oil flow to the cylinder head. Eventually lack of lubrication may cause a camshaft journal to score its camshaft bore and seize. Some engine builders drill the existing restrictor to .062? (1.575 mm) to increase oil flow to the cylinder
Camshaft & Valvetrain Technology Overview
Camshaft and valvetrain technology is a topic we’ve written much about over the years. A rotating eccentric lobe on a camshaft still opens the valves. In the case of an overhead valve engine, the cam lobe pushes a follower or bucket tappet to open the valve. With a pushrod engine, the cam lobe pushes a
SEMA Hall Of Fame Names Four New Members
Hundreds of industry professionals will gather and pay tribute to the new Hall of Fame members during the SEMA Installation Banquet & Gala Fundraiser, Friday, July 27, at the Sheraton Fairplex Hotel & Convention Center in Pomona, Calif. Nick Arias Jr., Nick Arias Racing Components – Arias has been finding ways to make engines work
Cleaning Engine Parts: Can You? Should You?
Here’s the kicker – those shops who feel that proper cleaning is too difficult, too time consuming or too expensive are actually leaving money on table when it comes to their engine parts. “At one point in my career, cleaning seemed like it was really difficult,” says Dave Arce of Arce Enterprises, El Cajon, CA.
The Nitty Gritty of Abrasive Safety
Conventional abrasives have kind of taken a back seat to PCD and CBN cutters in the automotive world in the last few years. Since most engines being rebuilt these days are made from multi-alloy components they are more easily machined with PCD or CBN. But PCD and CBN can’t do everything, so abrasives are still
In Chrysler
The trouble with timing goes on and on. However when it comes to the right timing on engines, especially single and dual overhead camshaft engines, it is absolutely critical to be correct. There are very few OHC engines that are not interference, either, so you are very motivated to making certain that camshaft timing is
ZDDP: When, Where, What, Why, How?
Government regulations and demands for lower emissions levels become more important than power and performance. Proven components are no longer acceptable and the inevitable changes occur – not always for the best. Things seemed to be much simpler in the 1930s. Engine bearings were made from a soft tin/copper/antimony alloy, commonly referred to as babbit.
Building Ford Strokers Engines: Make Most of a Windsor Block
Nijssen, the Apple Valley, CA-based engine builder, operates strokerengine.com and builds domestic V8 engines for the U.S. and international (primarily Australian) enthusiast markets. He says he doesn’t try to push his desire onto the customer. “I don’t sell you what I like, but rather you and I figure out what you really need for power
Camshaft and Lash Adjuster Design Change for Ford 5.4L-3V Engine
Do not use 2005 MY parts when servicing a 2004 MY engine, or 2004 MY parts when servicing a 2005 MY engine. If parts are intermixed during a service repair, the engine may exhibit noises on affected cylinders and engine damage may result. ACTION Order and install parts for the correct model year engine.

Toyota V8 UZ Engine Timing Belt Issues
When I first started researching this article, I called and stopped by several shops that do work on Toyota vehicles. I asked if any of them had any V8 models coming in for timing belts so I could get some pictures of the process. Either a blank stare, or a question like: “What Toyota V8?”
