Hey all, im in the market for a new carb for my 442. Here are the specs...

its an original 1970 455 rocket bored 30 over
stock internals
stock heads
headers/exhaust

Now I would like to know how big of a carb to get since the 'ol rochester shit out. Im thinking around 850cfm would be nice. I am putting new inernals later this year, and may do some head work and I need a carb that I can use now and after the buildup. Compression is stock, and I dont think Ill bump it above 10:1 (Im thinking of supercharging it. Has anyone been blessed enough to see a supercharged bigblock? What kind of numbers was it laying at the wheels?

Also, I need an aluminum radiator (the bigger the better) for the 442. The stock GM core sucks (i have a new OEM one and it still runs alittle warm).

Finally a good local shop I can buy this from. I only know of blue coral but Id rather a shop that specializes with GM parts. Would it be better to order offline?

Thanks for your help all, this project is going to be done shortly!
