Tech @ BG Posted April 10, 2007 Share Posted April 10, 2007 The majority of SBC camshafts will run even or better yet more duration on the exhaust side to help scavange due to the cylinder head design. Running more duration on the intake, wouldn't promote complete cylinder filling, then from there the other events do not seem to be optimal for throttle control / drivaiblity. Have you check your spark plugs to see how they were burning during your dyno pulls? Quote Link to comment Share on other sites More sharing options...

Tech @ BG Posted April 11, 2007 Share Posted April 11, 2007 Shut it down at WOT and checked plugs. Dry Sooty Black. How hard did it pull, and what RPM did it pull to? Quote Link to comment Share on other sites More sharing options...
v80z Posted April 11, 2007 Author Share Posted April 11, 2007 Pulled hard to 7000 rpm shift light there. Quote Link to comment Share on other sites More sharing options...
Tech @ BG Posted April 11, 2007 Share Posted April 11, 2007 What has your chassis dyno guy had to say about this? Looking at your dyno runs, you should have hit your face on the windshield before 7000 the way the HP is falling off. Quote Link to comment Share on other sites More sharing options...
