So I got a 2000 blazer but I blew up the engine off-roading it oops my bad I guess and I got a 350 small block vortec from a 1996 1500 wondering if anyone can help me with parts that would be compatible specifically long tube headers that would work with a 4wd model or if I have to put a straight axle and convert to a 2wd for long tubes to work which I’m not against doing also I have got a 8.5 10 bolt rear end out of a Zr2 wondering if anyone has experience with trying to put in the ball park of 400-500 horse up against a stock one I know the stock transmission and driveshaft will be begging me to be nice but I will replace them further down the path
