stock for a 350 would have been a 3 row, at least my 350 auto was for 72.

He has a nice 1970 esprit and is new to Pontiacs and needs our help. The 350 original engine has 11 heads and rebuilt to 389 too. I will post pics of his radiator too

can you clarify a few things? you said he has a stock 350, but then said "rebuilt to a 389??" you said the engine was flushed, how? if its the stock water pump its safe to assume it has the rear plate, tubes. new t-stat should be working ok. if you replace the water pump be sure to clearance the gap between impeller & plate, most guys say it needs to be done but others say they never do it on higher power engines with no problems but its a good idea to do it.
best to get rid of those electric fans & shroud & go to a stock fan with clutch. electric fans can work if they are good brands with high CFM airflow, those no name ebay fans are most likely junk.
