Started in 1984, by a young man who was and still is crazy for this industry, William Embry Herrick is street racer who went legal in the NHRA and IHRA. He’s the type of guy who thinks outside of the box and he doesn’t like to hear “that can’t be done.” He will find a way or create a process to get it done. CNC BLOCKWORKS is was at one time just an idea and now, it’s a reality. Now located in Piney Flats, TN, he provides high quality machining processes with availability to everyone. You can order a new block and have it machined to your specs or have us to spec it out for you. CNC BLOCKWORKS uses Rottler’s F69A boring center and an H85A cylinder hone. We concentrate only on one block at a time, start to finish. He has a partnership with Straub Technologies and you can call Straub Tech (423-391-7774) or direct to CNC BLOCKWORKS (423-391-7803).

Gen III/IV LS Steam Line Kit(346-4444)

LS Head Gasket Replacement for MORE POWER!!!

Is there HP and RPM to be gained by replacing head gaskets on and making cooling system modifications to your Gen III/IV LS engine? Yes, and it’s been proven by Robert Yates Racing Engines in their continued development of the GM LS Spec engine for circle track racing.

RYRE pulled a track-tested engine out of a race car for endurance testing which had the OEM-type head gaskets and cooling system that was run in the car. Testing also included using the radiator right out of the race car. During testing, RYRE simulated the operating temperatures that the engine saw during races and it was noticed in the overflow tank that the engine was venting out of the radiator cap. Some head scratching went on with the results of the engine and cooling system testing. Donnie Lewis, part of the RYRE development team and Art Leniti from Arts Radiators, started researching the LS engine program and GM's focus for the engine platform; emissions legal for the EPA and better fuel economy. Donnie and Art’s research revealed that GM achieved this through heat! Increases in the operating temperature related to the fuel operating temperature and the higher the fuel mileage and less emissions due to the heat that is needed for the catalytic converter to function efficiently. As more fuel is burned, there is more energy generated. In the confined space of a cylinder, this increases the pressure and hence the temperature, which is converted via the Otto cycle and the engine design, into mechanical energy to operate the engine. The energy realized is related to the temperature difference; the higher the combustion temperature and the lower the discharge temperature, the higher the efficiency of the engine and the more gas mileage you'll achieve. In addition, to meet EPA efficiency and emission regulations, OEM manufacturers use 200 or even 210 degree thermostats.

We all know running an engine cooler will produce more HP, but sacrifices fuel economy. RYRE needed performance and reliability for their race engine. Inspection of the head gaskets revealed that GM limited the water flowing around the combustion chamber to maintain the higher operating temperature. Additional evidence of an imbalance in cooling between the right and left head was evident because of the factory plumbing. RYRE modified the plumbing to consist of equal-length lines with a T in the middle running to an expansion tank just under the radiator cap. This allows the gases to leave the heads equally.

RYRE pulled the stock head gaskets off the test engine and punched seven missing holes in the them. Being that this engine was a spec engine, power output and RPM range of power was well documented. These engines, when reaching operating temperature, had always “laid over” on the straightaways and just quit pulling. RYRE’s cooling system modifications with parts from Art’s Radiators by RYRE were quite amazing. A simple few holes and some plumbing changes to add additional cooling and release off gases allowed the engine to continue pulling through the entire RPM range! All of this was from modification to the cooling system. Additional track testing showed that the engines ran cooler on the track.

At the end of the day, Donnie Lewis of RYRE used simple physics to convert an EPA emissions engine into a 600HP NA race engine that runs to 7800RPM!!!!

Straub Tech’s relationship with RYRE has given us the opportunity to take this tech and turn it into a product for the performance LS customer. Available in small bore and large bore, the Straub Tech MLS gasket features the additional cooling holes that allow for more HP and higher RPM!!

“GTA Street Cams”

If you want more power out of your AFR/Brodix/Dart/Edelbrock/ProMaxx headed BBC, look no farther. The “GTA” Series of Street Performance Cams from Straub tech will boost the power on your RAT like no other hydraulic roller cam kit.

These cams have been engineered to feed the demand of your Rat based on CID and cylinder head. Your CID and desired rpm range sets the demand of the engine. The cylinder head based on its flow chararacteristics will deliver the air and fuel. Since there are multiple options in heads with different flow rates, then you need a camshaft based on what the heads can supply. The GTA series of street performance hydraulic rollers makes this easy. You select your engine combination and then cylinder head and we supply the camshaft. Straub Tech takes the guessing out of camshaft selection.

Straub cams are worldwide proven by HP crazy customers. These cam kits all but guarantee the hotrodder the performance he is after with his performance Detroit V-8.
