Cam Packages

Cam selection is where most builds get ruined. We spec around your mods, gearing, fuel, and how you actually drive the car with all supporting hardware sized to the cam.

Head & Cam Packages

CNC head work, valvetrain, cam, and the supporting parts to hold it together. We work with Frankenstein, Late Model Engines, and Gromm Racing Engines on head work depending on the target.

Supercharger Installs

ProCharger, Whipple, Magnuson and A&A, authorized across all four, which means correct kits, real support, and warranty coverage that actually applies. We handle fuel system upgrades, cooling, and supporting mods so the car doesn't run out of fuel or heat-soak at the top of third.

Forged Engine Builds

Bottom-end work for boost or high RPM. Forged rotating assembly, correct ring gaps and clearances for your combination, assembled and measured properly. This is the work we're proudest of.

Header + Exhaust Installs

Long tube and mid-length header installation and custom exhaust work.

Flex Fuel Conversions

E85 capability with proper sensor integration, fuel system sizing, and tuning to match. The cheapest real power available on a boosted LS or LT, if it's done correctly.

Dyno Tuning

HP Tuners calibration, primarily on builds we've assembled ourselves. We spend the time datalogging and refining to make your car running properly.

Performance Packages

Pre-spec'd combinations by platform and power target, from a wake-up-the-car stage to full builds. Call and tell us your number and we'll tell you what it actually takes to get there.

WHY CONWAY Motorsports

Why Bay Area Customers Make the Drive

  • We're not a general performance shop that also does Corvettes. LS and LT is the entire business.
  • You get real numbers before parts are ordered. If the scope changes, you hear about it before we proceed, not on the invoice.
  • Call us and you'll talk to someone who wants to hear what you're doing with the car. We'll tell you honestly when a build target doesn't match the budget, and we'll tell you when you're about to spend money on the wrong part.

What our customers say

Sam is the best guy to take your car too. I have a late model GM ( 2019 C7 ZR1) and they are the best shop in California. Sam and his team are the only people who I am comfortable leaving my car with it. They go above and beyond In the details to make sure everything is right. I can go on and on about this shop. They’ll see my car soon again!
I just want to give a huge thank you to Sam and the entire team at Conway Motors. You guys really took care of me from day one. Sam was honest every step of the way, kept me updated, guided me on the right parts, and fixed every issue the right way.
If you have a late model GM car and need some more performance out of it, make sure you give Sam a call before you take your ride to any other shop! His shop will do the job right the first time. Period!
