SquareBore to Spreadbore Adaptor Plate! (Is it Necessary?)

[i8tokyo]

I've had the adapters and they work ok. I never noticed a crack, but it did develop a small vacuum leak on the manifold side after awhile. I got a deal on an intake and never looked back. One thing I can highly recommend is a heat insulator gasket with an Edelbrock carb. You'll be happy you did in the summer months.

BTW, the Edelbrock intake you would want would be pn 2161. I got mine off ebay for $50... It's for the peanut ports that I assume you have.

I didn't know if I should believe him or punch him, lol, so I walked away empty handed! Ya know a big block aluminum squarebore intake manifold doesn't sound like a bad idea now, Lol!
