Mounting a Rochester on a Square bore intake?

[angelorayhurst]

I have a 78 c1o Blazer that has a 350 crate engine with a Holley carb and Edelbrock Performer rpm intake that is square bore. I would like to put a rebuilt Rochester in. Is there a good adapter I can use for this? What are the pros and cons? Would it be best to just get a Edelbrock Performer intake and just forget the adapter? I would like to save a few coins and time, but would it be worth it. Also which adapter is best if I go that route. The engine is stock with dual exhaust if it matters. Thanks in advance for any info..
