PERFORMANCE ENGINE PLANNING & BUILDING
Street Performance & Racing Engines
When it comes to performance engine builders, Simpson Racing Solutions is the top choice for race car owners and hot rod enthusiasts alike. Our knowledge of racing, building, tuning, and dyno testing means that we will provide an engine custom-tailored to suit your needs. We are constantly learning on our in-house chassis dyno and flow bench and applying our knowledge to every build we perform.
We will design your project using proven planning techniques, years of experience, and the best selection of engine parts available to meet the needs of your late model or classic application.
Each engine assembled by SRS includes over three pages of extensive engine blueprint documentation.
This is the engine that your project deserves!
Dyno Break-In & Tuning
Critical components of each build are the break-in procedure and initial testing. At SRS, we can break in and tune a combination on our Superflow chassis dyno before it ever leaves our shop. Options are available for engine dyno testing as well. Learn more about our in-housedyno tuning!
Dyno testing allows us to tune several variables including:
Before turning over your new engine, we have the ability to perform a proper break-in procedure on our in-house chassis dyno. This is an important first step for any new engine to ensure proper piston ring seal and camshaft break-in. It also allows us to properly set up the fuel curve with our wideband oxygen sensors and optimize ignition timing and fuel jetting. Rest assured that when your new combination leaves our shop, it is ready to hit the track, strip, or street.
All-Inclusive Engine Building, Installation &Testing Services
At Simpson Racing Solutions, we do it all for you, handling your full project rather than tackling it in a piecemeal fashion. We offer an all-inclusive shop service, from removal and installation, through dyno tuning and break-in tuning; we've got you covered. We can also ship your new SRS-built engine at reasonable rates if you wish to install it yourself.
With decades of experience behind us, Simpson Racing Solutions will get you the optimal results you are looking for. We look forward to working on your performance engine project. Check out the rest of our site to learn more about the parts and brands we carry, who we are, what we do, and the ways we can help you get the performance engine you have been dreaming of!
A custom-built engine lets you build an engine to specifically meet your performance goals and budget. We have modified crate engines because they fell short of the customer's expectations.

Break-in Testing & Tuning
Before turning over your new engine, we have the ability to perform a proper break-in procedure on our in-house chassis dyno and/or on an engine dyno at our partner facility. This is an important first step for any new engine to ensure proper piston ring seal and camshaft break-in. It also allows us to properly set up the fuel curve with our wideband oxygen sensors and optimize ignition timing and fuel jetting. Rest assured that when your new combination leaves our shop, it is ready to hit the track, strip, or street.

CYLINDER HEADS - PORTING, MODIFICATION, TESTING, & SALES
CYLINDER HEAD SERVICES...
LS7 Head Repair
We have completed many LS7 cylinder head repairs and know what is needed to prevent catastrophic cylinder head failure on these engines.
CHASSIS DYNO TESTING & DYNO TUNING
We offer complete chassis dyno testing and tuning services on our Superflow Autodyn30 chassis dynamometer.
About Our Superflow Chassis Dyno...
Our SuperFlow AUTODYN 30 Eddy Current Dynamometer is capable of measuring up to 2,500 RWHP at over 225 mph and holding up to 1,100HP for steady-state testing. The AUTODYN 30 has the ability to adjust vehicle load. This is ideal for EFI tuning and testing various ignition timing configurations (for various gear ratios for example).
Not only do we provide horsepower and torque numbers, but we also provide objective and consistent results. Our dyno also features dual channel wide band O2 sensing and logging capabilities.
Does SRS Tune EFI Systems?
We have hands-on experience tuning many EFI platforms, including Holley, Megasquirt, ECUmaster, various OEM vehicles, and more. Occasionally we have a request to tune a platform that we are not well versed in. In these instances (and with the vehicle owner's consent), we consult with industry-leading experts to complete the tuning process remotely using the SRS dyno for data collection and analysis.
Can I Test My Racecar on the SRSChassis Dyno?
Absolutely! Just keep in mind that if you have a drag racing car with an automatic transmission and high-stall converter, the dyno data will be inaccurate below the converter stall speed. Having said that, we break in parts, test, and tune the 7-second quarter-mile E.T. SRS altered on our in-house chassis dyno. We have tested and tuned 900+ horsepower supercharged, turbocharged, and nitrous-assisted door cars and dragsters on ourchassis dyno.
What Should I Do Before Visiting the Dyno?
You will want to use our time together effectively. This means that you will want to be sure little things will not consume valuable dyno time. Here is a simple checklist that we recommend you review before visiting the SRS shop for your dyno session...
At SRS, we conduct a pre-dyno inspection to help ensure that the vehicle is safe and ready for dyno testing before we strap your ride down on our Superflow Autodyn 30. Here is a link to our pre-dyno checklist.
How do I Book a Dyno Tuning Appointment?

POPULAR ENGINE COMBINATIONS
At Simpson Racing Solutions, we specialize in custom engine builds tailored to your specific combination, performance goals, and budget. However, over the years, some popular engine combinations have emerged. Here are a few proven short block combinations that have emerged as rock-solid foundations for your next engine project. Purchase as a professionally built short block complete with blueprint documentation and complete the final dress (heads, camshaft, intake, etc.) yourself, or work with SRS to create a complete engine package that is turn-key and ready to perform... the choice is yours!
363 SBF SHORT BLOCK
A rock-solid foundation is capable of big power output. The backbone of this build is a Dart block that utilizes an 8.2" deck height. An internally balanced crankshaft with H-beam connecting rods and forged pistons are boost or nitrous-ready. Various compression ratios and options are available depending on the build specifications.
Machine Work Details
A) Yes, we offer many different piston options to suit your application, including custom pistons with custom dome profiles to fit your high-performance cylinder heads.
383 SBC SHORT BLOCK
This short block is an excellent replacement for a tired 350 or a great foundation for a new build. A proven combination of parts offers great value and nice power potential. With a few optional upgrades and the correct top-end package, BIG power can also be had in NA, boosted, or nitrous-assisted form. This is a very versatile combination.
Machine Work Details
A) If you plan to run a power adder on your SRS short block, we suggest upgrading to a forged piston at a minimum. Connecting rod and crankshaft upgrades are also available depending on the desired power level.
