today i ttook my 79 350 and removed all the front drive brackets and pulleys and h20 pump. i then cleaned the front face of the block and heads to remove grease and dirt. installed h20 pump from doner 89 burban 350. then installed pass side bracket setup. found only 1 bolt hole not drilled and taped in head. but this should not be a problem as there were 5 and 2 brace rods. so now there is 4 and 2 rods. i then installed a a/c delete bracket and pulley. this side also needed a small twek of the fuel line. next was the drivers side bracket install. all bolt holes lined up good. installed them and secured the altenator to the bracket. next i need to get a change over plug for the old style to the new style plug. next was the p/s pump. i was not sure if this was going to clear as it is a 3 hose hydroboost pump and older resivor. but against all odds. she bolted up perfectly. then i installed the serp belt pulley on the pump. next was the h20 pump pulley . last was the main belt. then i changed the thermostat as i needed to change the water neck out for a stright one so it would clear the hose to brace rod for the pass side mount bracket. all i can say is you need to do this. its easy and wow is it clean and simple to work on now for a belt change. those multi bolt to adjust v pulley brackets sucked at times. took me about 3 hrs to do. if you use the stock hardware to block studs . you will need the inverted torqs bit sockets to remove them and install them easy. just go to the junk yard and look for 88-91 blazer/burban/crewcab for the parts. or a 88-up new body style will work also.
