This motor was in my street car F-body aspen that weighed 3600lb with me in it and ran 11.70's at 115 on pump 93. There was nothing fancy just a good combo. This car also has power steering and factory water pump which was robbing a few horsepower.
I hope this helps if you have any ?' feel free to pm me.
