They are actually quieter than I'd like them to be. https://www.youtube.com/watch?v=28K935z94dI https://www.youtube.com/watch?v=wBphOshIgiQ https://www.youtube.com/watch?v=D3dQZJPMR68 CHIP '70 hemicuda, 575" Hemi, 727, Dana 60 '69 road runner, 440-6, 18 spline 4 speed, Dana 60 '71 Demon, 340, low gear 904, 8.75 '73 Chrysler New Yorker, 440, 727, 8.75 '90 Chevy 454SS Silverado, 476" BBC, TH400, 14 bolt '06 GMC 2500HD LBZ Duramax

That combination had an awesome sound....real hollow and deep like the cam was deep back in a cave if that makes sense. At full throttle though, it shrieked like a monster.

They are quite idling and cruising, but get loud at wide open. They are heavy thou. http://www.youtube.com/watch?v=aIxaesJ190U http://youtu.be/lCZAaN7fFLg

I have just about all the parts at this point. Taking my rotating assembly to Best next week for balancing. I'm guessing mine should make at least 800 off the crank. http://www.youtube.com/watch?v=aIxaesJ190U http://youtu.be/lCZAaN7fFLg

It's been 9.50s at 140+ mph on motor only at 3800 lbs. I've been 8.90s on nitrous, but should be in the mid 8 sec range now. I've been a good bit quicker at 1/8 mile tracks since doing some tuning. Just haven't had the chance to run it at a 1/4 mile track in a while.

I went 8.90s on 250 hp. Spraying 300 now. This was w/ a pair of dynomax bullet race mufflers. Poor quality video a friend of mine took for me. This was 8.91 at 151 mph. https://www.youtube.com/watch?v=qaLUpFxKAZs CHIP '70 hemicuda, 575" Hemi, 727, Dana 60 '69 road runner, 440-6, 18 spline 4 speed, Dana 60 '71 Demon, 340, low gear 904, 8.75 '73 Chrysler New Yorker, 440, 727, 8.75 '90 Chevy 454SS Silverado, 476" BBC, TH400, 14 bolt '06 GMC 2500HD LBZ Duramax

This is dual 3" with h-pipe and tailpipes. https://www.youtube.com/watch?v=422uTiz78bs Off topic but tying the hood lights into the shift light is an awesome idea. Now that is a shift light.
