SCAT EXTREME DUTY SBC COMPETITION SERIES ROD UPGRADE NOT FOR OUTRIGHT PURCHASE

Do not purchase this item unless you are buying one of our rotating assemblies, short block kits, or engines.

This is an upgrade for those that have purchased a rotating assembly, short block kit, or engine from our other listings.

IMPORTANT NOTE!

Recommended for those running hard. The regular Scat rods that come with your assembly are sufficient for most street rod uses, but the Scat Competition series rods offer more security against rod breakage under hard use, and they have the huge ARP-8740 7/16's cap screws. The Competition rods have a 600+ Hp rating, and the slight cost to upgrade is well worth it in our opinion. We use the very same Scat Competition rods in our 600+ hp 427 and 434 engines.

The Scat Pro-Comp extreme duty I-beam rods should not be mistaken for ProComp rods. These rods are made exclusively by Scat, and have nothing to do with the ProComp company. The critical sizing and installation of the ARP 8740 cap screws is performed on a Sunnen machine in the USA by Scat Industries. These rods are excellent for those wanting the extra security offered by a rod with 7/16 ARP cap screws.

Take notice of the design of these rods. They are far superior to conventional style I-beam rods. We are now using this rod in all of our Stage 4 and 5 SBC engines. These engines are making up to 610 hp. We also use this rod in our big block 540/555 engines, making approx. 700+hp.

If you do a search on the Scat Pro-Comp, (Competition Series) rods, you will find a vast amount of info on many car forums. All of the info is 100% positive. These rods are run in engines that not only produce high horsepower levels, but also run at continuous RPM. Notice the general appearance in the pictures. These rods do look impressive. The style is reminiscent of a steel billet rod. They are clearanced well for most stroker applications, but as a rule, do check for clearance before finalizing your build.

The fact that these rods are incredibly strong and well made, coupled with the fact they are light weight and offer better clearance than any H-Beam rod on the market, made it an easy decision to use them in all of our high horsepower street/strip engines. This is the perfect upgrade to your rotating assembly.

When comparing our prices, be aware that Scat also offers a low cost I-beam rod. It is not comparable to this in any way. For the slight difference in price, the Competition Series Scat I-beam is the way to go.

To move up in durability from the Scat Competition I-beam rods, you would have to go to the Genuine Scat H-beam rods. The rod bolt length on the H-beam rods would be its best advantage as they are approx. 150 thous. longer and offer a greater pull apart rating. This higher pull apart rating would be advantageous in applications running at extremely high rpms and/or coupled with heavier than normal pistons. The rod body on the Scat H-beam rods are also much heavier. This could be an advantage on engines running extreme high hp levels above 700.

All things considered, we think the Competition I-beam rods would be bullet proof in just about any street rod below 700 hp. The failure rate with these rods is nearly non-existent, especially in engines running below 7000 rpm.

Important note about H-beam versus the Competition I-beam rods from our company president, Skip White.

H-beam rods are often heavier and create much unwanted reciprocating drag in the engine. Some H-Beam rods are so heavy that balancing the crank becomes difficult and costly. Heavy duty H-beam rods do have a few benefits over these rods, but they would only be called for in extreme buildups. If you did find a lighter weight set of H-beam rods, equaling or close to the weight of the Scat Competition I-Beam rods, then I would assure you that the Scat I-Beam rods would be stronger ounce for ounce with the exception of the pull apart rating due to the fact that H-beam rods have longer bolts in them, and this can pose a clearance problem for those running stroker cranks.

Should your engine be set up to run high rpm, and you did use a heavier rod that was possibly stronger in a few areas, then the excessive weight may become its worst enemy and could negate any benefits from the added beef. This is why the Scat Competition I-Beam rod has done so well in the racing events where engines are turning high rpm for sustained periods of time.

I really do like the design of the Competition Series I-beam rod, and I've read every review on most every car forum out there. I hear nothing but praise for this very special rod. We do offer lower cost rods, but this is our best value all things considered. When I hammer down on an engine, there is one concern I have more than any other, and it's whether the rod is going to pull apart or break due to fatigue or excessive stretching. I have personally spoken to the owner of Scat, and he has expressed great confidence in what these rods are capable of handling. They are running in engines that have seen many seasons of brutal racing, and you really never hear of a failure. If you're going to run them in a street/strip car, then you may very well have a lifetime set of rods. Do remember when a rod breaks or pulls apart in the engine, there is a great chance you will lose your complete engine.

Be sure and check sizing on these rods before installation. The Scat rods are often perfect in sizing as they should be, but it would be very risky to assume they are perfect. Many of the cranks on the market are not perfect on sizing so even though the rods would be at what is considered perfect sizing, the crank journals may be on the thin or fat side.

NOTE: THIS IS AN UPGRADE TO RODS INCLUDED WITH OUR ROTATING ASSEMBLIES, SHORT BLOCK KITS AND ENGINES. THIS ITEM IS LISTED IN OTHER LISTINGS AT FULL PRICE AS AN OUTRIGHT PURCHASE.
