Just starting a 1938 standard coupe has juice brakes and a 1939 tranny. Will an 8BA fit without radiator modifications or should I stay with an 59AB?would love to stay with a flathead but am not supposed to a SBC either but a flatheads hat fits would be faster. This car has had no modifications to the sheetmetal or frame and I like that. It has been in storage since 1964 and is pristine. Old hotrod and just want to keep it nastalgic. Just don't want the Babbitt bEarings of the stock motor. If there is room for for the 8BA it is just a little boost in HP. But I realize they are 2 inches longer any one done this swap? Any room issues?
