as said above there will be power brake vacuum problems with the original tight lobe cam.
they do make great power.my satellite has run as quick as 11.35@119.01.
my car is a daily driver,i run a vacuum pump for the brakes,it idles at about 800 rpm in gear.it likes a good converter,32/3500+,3.9+ gears.yes it is soft under about 2800rpm but that is good as i run a 235/75/15 street tyre.
fuel consumptiom - pffft - you've got 440ci what do you want ? you sound like a hotrodder
