High Output Heater Option
Is the core the only difference?

Can I put a High Output heater core in my 79 no AC heater box?


Or is the heater box different too?

It won't fit, the hi-output core is 6x8" the standard core is 6x6".

I've got the high output heater, the cores are different P/N if I remember right. There's pictures of the box in this thread:
