THE DYNO RUN Build, text and photos by Mike Mavrigian . Well, we finally ran this engine on dyno. The dyno location was Platinum Engine Designs in Norwich, Ohio, a clean-as-a-whistle top-notch race engine shop in southeast Ohio, equipped with a late-model SuperFlow engine dyno.

Whenever I build an engine, regardless of my confidence in terms of fitting and assembly detail, I’m always a bit apprehensive when it comes time to light the fire. But when things go picture-perfect and you hit high numbers without a single glitch, it’s a feeling that’s better than sex (I’m sure you know what I mean). This LS program proved to be a total success.
Here’s our LS with our carburetor setup and coilpacks. This setup will utilize the MSD timing controller for ignition control/adjustment. No ECU is required for this approach, which makes it ideal for application in any street rod, muscle car, race car, etc. that is not wired for computer control. For our coilpack versions (for either [...]
CARB WITH DISTRIBUTOR, NO COILPACKS The next carb-type setup involves the same intake manifold and carburetor, but with a twist-get rid of the eight individual coilpacks and mount a distributor at the front of the engine. GM Performance offers a distributor adapter kit (P/N 88958679) that includes a cast aluminum LS front distributor drive cover [...]
