Hi all,

I am planning on replacing a 1" aluminum carb spacer with a phenolic carb spacer on my 1970 440 w/ a stock intake manifold and 750 CFM Edelbrock carb. I have a couple of questions for those out there who have done this:

1. Does a stock 440 manifold use the "open" or 4- hole spacer? I think it's open, but don't have access to the car for awhile to check it.

2. Any recommendations on one that works well on dissipating heat? I see Summit sells their own model and also carries an Edelbrock brand. Any preference?


Thanks much for your help!
