Couple of questions.
Apparently a lot of the new radiators come with 19# caps. How do you feel about that?
I have not doubt the radiator can handle it. The 1968 WP was designed for 15#. Is it safe at 19? I think hoses are fine if quality and in good shape.
My biggest concern is the 56 year old heater core. I HATE replacing heater cores in these old cars. I just don't see a downside of running a 15# cap, so that is what I am doing for now.
On another note, there is a really slick way to ad a coolant recovery system on first gen Camaros.

I bought one of those and will be installing on my Z.
Is there something comparable for the 60's Chevelle / El Camino?
The Nova tank will not fit on the El Camino. I already tried. To complicate things, mine has factory A/C, so not as much room under the fender next to the battery.
Anyone deal with this?
