The 508 number was at the engine and the 560number was at the wheels. Both setups made around 500 hp at 5000rpms. I didn't run the engine on a dyno with the EFI but guessing on drive train loss it looks like the Weber's can compete under 5000 rpms. The EFI was able to keep up with the airflow all the way through the curve. The throttle bodies will flow 90 cfm more per barrel than the standard 48 IDA. Aside from horse power, the EFI is much easier to tune in my garage and runs so much smoother without any stumble. I built an engine to run at higher RPM's but the Weber's can't do that on a larger cubic inch engine.
