i recently purchased a 98 long block vortec motor to install into my 90 k5 blazer. before i drop it in i wanted to put in a cam to wake it up, i purchased the tbi to vortec intake from gm and currently looking to upgrade my t.b.i. also but not sure which cam to use. im running headers,4:88 gear,chip,msd, and 38" tall tires if this helps on cam selection. im also thinkin of running a 1600-2000 stall convertor any advice would be greatly appreciated...... also i searched message forums and really couldnt get an answer either before someone tells me too.
