434ci Small Block Chevy Gets High-Tech EFI Upgrade with Holley’s New High Ram

It's time to team up with my dad, Bruce, to upgrade his 434ci Small Block Chevy-powered Class 8 race truck with Holley’s brand new High Ram EFI system — a setup that debuted at PRI and now supports direct port injection for Gen 1 SBC engines.

Bruce might be an old-school carb guy, but with Holley’s Terminator X ECU, dual-sync distributor, and plug-and-play harness, it’s never been easier to go full EFI without sacrificing that classic small block soul.

Special thanks to Holley Performance for continuing to innovate and support small block Chevy fans. Dyno runs, tuning, and desert testing coming soon!
