If it was mine, I wouldn’t cut it up for a 26 inch radiator unless I was gonna have A/C or use it for towing. I would also use 180° thermostat.

I also have a Mega block 528 in my Challenger that I street drive and it makes over double the horsepower my other cars do, with a 26" core support and 26" radiator. It also runs way cooler than the other as well. I never see above 171 degrees in this car even in normal traffic on a 95 degree day.
