what waterpump to use?

[hd91lowrider]

I'm building a 347 stroker. 1983 timing cover with mechanical fuel pump. March pulleys. (alt/crank/waterpump). I tried a 83 mustang pump. (pulley holes were different) Then an F-150 pump. (pulley holes line up but had a few extra bolt holes. Looking at a pump for a t-bird or fairmont but supply house is getting sick of ordering pumps for me. lol. What waterpump should I get too make this work. Thanks guys

I bought and returned eight water pumps before I got the right one....for me. I have a 351 with a Silver Seal timing cover TW6600, March pulleys, V-belts, standard rotation. I used this pump from O'Rielly Auto Parts

Go to Advance Auto and ask for a 125-1700 This is a standard rotation water pump. Uses the same bolt pattern as the Mustang pump.
