If it's anything besides a flathead V8 an simple and cheap 65 to 67 Mustang V8 radiator will work just fine . I was using one in my 55 Ford with a 272 and had no problems at all . They are just a little over $125 new ! Jim
Here is a pic of one installed http://www.jalopyjournal.com/forum/group.php?do=discuss&discussionid=22710&pp=20&page=2 The early 65-67 Mustang radiators can be had with both connections on the p*** side or if you use a later 302-351 they can have upper hose p*** side lower hose drivers side be sure and specify the way you need it,this is the one in the picture ;http://www.jalopyjournal.com/forum/group.php?do=discuss&discussionid=22710&pp=20&page=2
As a side note I sent Oscar's Radiators a pm to see if an additional top and bottom outlet could be added to use for the flathead V8 cars,I just spoke to Him this Sunday at the Swap Meet here in Phoenix and sent Him a picture of Baggs' install.The six cylinder Mustang radiators have room in the tanks to add the additional outlets see this picture :http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=250785959023#ht_1098wt_1165 I'll post what I hear as some of you may have found out the V8 radiators can run $450 and up,if this can be done it should save some major bucks.
