please someone help me out here. i have a 95 s blazer with the 4.3 vortec. i just swapped in a new (used) engine since i blew the old one, and the engine i installed did not have a distributor in it. my stock distributor has the side mount plug wires on the cap. If the engine i installed originally had a top mount plug wire distributor would my side mount distributor still function? And is there any internal differences between the 2 engines with the different distributors. the engine has all of the same sensors and plugged right in but i cannot get it to fire but have fuel and spark, however the gas is over a year old and it keeps flooding the engine. PLEASE SOMEONE HELP ME OUT WITH TIMING THE ENGINE AND MY DISTRIBUTOR QUESTION. Thanks much
