Is there a way to check the vacuum actuators on the heater box to see if they work before I put it all back together ? How much vacuum does it take to make them work. Thanks for your help

As stated, they are out of the car, new parts are expensive if the old sill work and can be refurbished.

In my restoration project of the 70 GTO I have my heater and A/C box out. Is there a way to ck the evaporator coil and heater coil for leaks and condition?

Thank you all for your help, I have located some # 13 heads, on guy will split them at $250 per or I can get a set delivered to my door for $325. Thought I would go with the single unless some one else needs just one. We keep everyone posted on the project.

magna flux showed a cracked head, anyone know where I can get a #13 head ?

A machine shop will be doing it, yes the pistons are 8.5 to 1. The cam I think is 3/4 lift, what the previous owner thinks. By rotating assembly, you mean the crank ?

Hi, I have a numbers matching 400 in my 1970 GTO. Doing a restoration on the car so we pulled the engine to go thru. The shop says it has been bored 30 over and 8.5 pistons installed in the last rebuild, don't know the cam. He said by the bearing numbers it looked like it was rebuilt around 2001 or so. He says it is showing some wear. My question is what would be recommended rebuilt if I just want to get back to stock or a little more, run on pump gas, idle and start nice but be able to light them up once in a while? It's an A/C and Auto Car. Thanks so much for your help
