Going to do a Rotisserie retoration of our 1971 Cuda. It will get a Hemi in the 500-600hp area. The car is a 318 chassi so I asume that the core support is going to have to be modified for a bigger radiator. My questions is, will a stock Hemi reproduction radiator be capable of cooling a Hemi like we plan to put in? If not what are some good option on alum. radiators that will still give the stock appearance and keep the beast cool?
