The Holden 253 Amca modified crate engine is designed with the best combination of power and reliability in mind to suit the popular Australian Amca modified speedway racing division, Although the Amca class is seriously limited by restrictive rules, we have spent 100's of hours developing this engine to be Australia's #1 Amca race engine providing superior power and reliability to many drivers including Adam King, 2008 SA champion, 2008-2009-2010 Victorian champion and 2010 Australian Champion and Jason Roberts, 2012 Western Australian Champion.
What you get with your Custom Crate Engine is a custom designed, precision machined, blueprinted and balanced engine using the best components for the Amca national V8 division, no short cuts, no exceptions.
Only available from Port City Engines...
All complete long motors are run-in and tested on our Superflow SF-902 engine dyno before delivery for your complete satisfaction. (Dyno results included)
