i ran my chevelle this past labor day-ran
[email protected] at 90 degrees heat.my current cam is comp 7/4 swap .748 lift 286/296 at .050 112 degree lobe ctr.dart 355 1150 three circuit dominator dart intake jesel belt.the scales said car and me is 2950 lbs.2 1/4primaries to 4"collector. 9" 4400 rated stahl-turbo 400.4.11 rear gear 33"tall m/t et street.car doesnt flash much at all past 2000 rpm(i atribute to cam and vehicle weight combo)my rpm at 142 is 6000 so with the right cam profile and on spray i want to have car peak rpm to be approx. 7000.currently, car is very doggy under 5000 rpm.(5000-8500 rating)
it seams like newest trend to get best results in pump gas motors is high lift cams and short duration=most power at 6500.so basically i want to get cam correct for 3800-7000 with peak horsepower to be around 6500 rpm cause i heard you want to have peak horsepower 500 rpm less than highest rpm motor will spin.i want to footbrake the car to about 3000 rpm then stomp on it to activate nitrous(cheap mans transbrake).i am very anxious to hear what you guys think.im thinking of leaving current cam specs alone but take out duration.............what would you do???thx!
