Believe in the GM HEI ignition now?

Here is a vid of my car before and after I installed a GM style HEI. First 20 seconds are before, cool sounding lopy cam right? Listen to it after the HEI was put on. Instant power. The way this car starts and runs now is unreal.

I bought the set up from FABO member Trail Beast. www.classichei.com but you can fab one out of parts from the local auto parts store or junkyard
