I would like to utilize the original heater but have read that the original heater cores can't hold up to the additional water pressure. Even Classic Parts now calls out in their catalog "Not for use with modern upgrades over 4# radiator pressure caps" I believe the small block chevys are running over 10# caps for pressure. (I am not able to spend the money on a new system, such as Classic/Vintage Air, at this time...)
Thanks!!
