Well i need to put the jegs catalog down... http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=3788&prmenbr=361 I'm seriously considering dropping one of these systems on the blazer as soon as my next 3 paychecks. anybody run one of these? Is there anything you need not included in the kit? fuel pump etc? What kind of life expectancy can i expect from my motor if i put this kit on? Does NOS kill a motor faster than N/A? Originally i was gonna put Darts and a better cam on to get it up to 400 hp and 440 ft lbs but that cost about 2x's as much as this system. with the NOS it'll be around 430 hp to 455 hp but the tq is what i'm worried about. I can afford a 14bff but the d60 is out of the picture for a few years. I know the stock 2 bolt crank has been tested to 500 hp but has anyone broken a crank with less than 500 hp? How much is it to fill up a 10 lb bottle?
