Maintaining Your Engine Crucial to Cam Performance

By Charles Reichard

As your car accumulates mileage, maintenance is essential to ensuring your engine doesn’t quit. Gaskets dry out, leaks and holes appear and belts stretch. Making sure your plugs and hoses are in top working order is also imperative. Poor maintenance can also lead to serious cam problems. READ MORE

 

Some thoughts on cam and lifter wear

By Charles Reichard

There has been a lot of discussion regarding the increase in flat tappet cam failure the last few years. Much finger pointing goes toward our only domestic flat lifter supplier, Stanadyne. We started using Stanadyne lifters about a year and a half before the lifter shortage hit. We had NO increase in lifter failures when we changed over. The lifters look different so there was no old stock involved or anything like that. One order we got Eaton’s and the next Stanadyne’s. The primary visible difference was the Eaton lifters were Parkerized on the bottom and the Stanadynes were not. The metering system is also different... READ MORE

 

2 Barrel Carbs

The 2 barrel carburetor in Oval track racing

This article is not intended as a do it yourself article but rather a guide to the modifications required to make 2 bbl carburetors competitive in oval track racing. Make no mistake; there are very few truly stock 2 barrel carburetors in oval track racing at any level. Since the Holley 4412 and 7448 are the 2 most popular carburetors used today, this will be the primary focus here. They are rated at 500 and 350 cfm respectively at 3 inches of vacuum. The 350 carb is most prevalent in the South and the 500 more popular in the North. The same problems exist in the Rochester and Motorcraft carbs but they are addressed a bit differently...

Choosing a proper cam for stock cars

By Charles Reichard

One of the most difficult tasks facing today’s racer is camshaft selection. The advertising in the camshaft industry is often misleading and contradictory. The important information about lobe designs is not available and if it were, few people would know what it means. Everyone wants the latest trick of the week and that trick seems to be whatever gets the most press. Have you ever read anything in a racing publication that was negative about an advertiser’s product? Not likely. Often an advertiser arranges the tests and you can bet it will put a favorable light on the featured item or you likely won’t read about it... READ MORE

 

Tuning Your Camshaft for Maximum Power

by Charles Reichard
(Written for Oval Track Racers)

Most Stock Car racers have been faced with trying different cams in their cars and not seeing the results they think they should. Frequently this is followed by selling or giving the cam to a fellow racer who finds it is the best cam he ever ran. Why did this cam work so well for one racer and not for another? The reasons can be many. Driver style plays a big part in the picture. A driver who can keep the rpm up in the turns will be able to use a bigger cam than one who drops a lot of rpm. The same cam in the car with lower turn speeds will not have enough torque at the turn exit because it will be below the maximum power band... READ MORE

Degreeing a Cam

1. Tools needed

a. Degree wheel.  Can be any size, Larger is more accurate

b. Dial indicator,  .500 or 1 inch (1 inch is usually cheaper)with a magnetic base or suitable bracket for attachment to the block or lifter bore.

c. Lifter, preferably with extension, or tool that holds the indicator and fits in the lifter bore.

d. Method for securing degree wheel to crankshaft. Ratchet adapter is best & easiest to use.
Adapter secured by balancer bolt is almost as good. It should allow wheel to be removed without disturbing the bolt. TDC must be reestablished each time that the wheel is removed.

e. Pointer: can be made up of metal parts or even stiff wire such as a coat hanger.

f. A positive stop to find TDC. Dial indicator can be used in several configurations such as a magnetic base or a U shaped bracket to position indicator over the cylinder.

g. Pen & paper to record your readings

Happy Customers

Charles,
Thanks for the great cam and kit.  With your 240/240 .410 lift lobes on a 110 center we made 365 rwhp in our 331" Nova with a 2-bbl carb, about 40 hp up from the Comp cam we ran last year.  The torque peak was at 4500 rpm and the power peak was at 6500 rpm, well suited for the long uphill road sections we use.  I had no problems at all with the engine, no valve lashing was necessary and we used one set of plugs for the entire race. We finished 2nd in our class behind a Corvette, and eighth overall in a field of 70+ cars.  We were complimented frequently on how fast the little Nova ran, finishing well ahead of several 366" 4-bbl cars.  If only we could corner with the Vettes....

Thanks again,
Mike
Fairfield, CA
