I want to use a fresh air deluxe heater. I really like the look of it hanging under the passenger side with the emblem showing.
My question is about the heater core and the pressure they are rated for. This link says not for modern applications without the 4# cap.

I've done a v8 swap. Lines are currently capped. What pressure runs through it now and can it be reduced?
What have some you guys done when swapping engines and keeping factory heater?
