Putting a small block Chevy in a stock body 1939 Ford sedan using a Chevy to an early Ford transmission adapter, will the wish bone need to be split?
No need to split the bones. Mine in avatar has a '62 283/adapter/stock trans and rear. Stock radiator with two holes blocked off. If you use a Hurst front mount you don't even have to drill a single hole. Convert to 12V and you're off and runnin' in a weekend.
Yes. The radiator shop can plug off the unwanted outlets. If you are asking if it works as far as heat transfer, Oh Yes! The flathead put out more heat than a smallblock
