radiator size

i'm building a sfbd frame for my 720 and we're working on getting the front end setup.  i need to know what size radiator i should get.
 my engine is a 305 chevys small block bored .60 over with a high lift cam and vortec heads.

we are thinking of mocking up a 4.3 radiator out of a blazer do you think this would be big enough if we allowed for at least an inch of clearance on each side?

hmm wrong forum sorry..

4.3 blazer radiatior is pretty wide. maybe check out one for a camaro or something

Personally I would step up to a summit universal aluminum radiator for about $160 for extra insurance.

I wanted to see if that was going to be about the right size.

you can get a summit or griffin in just about whatever dimensions you need and with inlet and outlet wherever
