okay im a new member here, and some of you do not know me, i also drive a blazer for a daily driver. well about a month ago it blew up, blew out the whole bottom end, crank, bearings, everything, well tomorrow it finnaly goes in to get fully rebuilt by professional race engine builders, i should have it back in about aweek, i cant wait, because i have been driving on snow with out 4WD in my old cutlass with no radio, and it sucks.
