Howdee...Have a 383 chevy in a 64 impala with a custom built crossflow radiator. Need to overdrive the water pump a bit especially at idle. Added Vintage air and temps climb in traffic or with a/c on. Will a Ford 289 5.3/4 water pump pulley fit on my 383 chevy water pump...or can you advise a part number for a chevy. Currently have a 7 1/4 crank..6 .5 water pump..need 2 grooves. any help appreciated. Currently have a fixed fan, metal shroud, small pusher fan on drivers side for a/c, automatic. Want to try this first, then maybe a Flowcooler water pump. All hoses new, fluid 50/50, motor with 1200 miles on it, fresh oil filter, timing , belts, chain etc. all new, great oil pressure...coolant temp 170 on road..but stop n go..or turn on A/C...to 180..190 200 210...then smells hot, hard to restart. Any ideas appreciated. PS this is for a friends Impala..NOT mine...
