I'm working on a 64 Chevelle W/ a 350 SB and TH 400. I would like to run a long water pump w/ the alternator in the 69 & later position since I don't like the header brkts for the short pump. The 64 radiator has the outlet on the pass side. I would like to use a 66 radiator w/ the return outlet on the driver's side. Does anyone know if the 66 radiator will bolt in??? I have to get a new radiator anyway and changing thermostat housing is not a problem.

Wheels E-mail me the bolt pattern off the rad. support. I have mine out of my 66 right now and can measure it. I think they are interchangable, but now we can check to make sure. Rick.....

I have a 64 with a bib block and any time i order something related to suspension cooloing etc i order it for a 66 396 car. I currently run a 66 4 core rad no problem bolt in . Good Luck

Rick again, I measured between the mounting holes were the spotwelded nuts are. I get 27" across and about 9 3/4" up and down. Hope this helps.

Thanks for the info. Looks like I'll go w/ the 66 rad.
