i bought a 4 barrel 327 intake and can't figure out what it is off of - the seller said it came off of a 63 corvette - the numbers off of the intake directly behind the carb are 3872783 - can anyone help or do you know where i can get help? every 4 barrel rochester quadrajet i have does not fit properly because the 4 holes that bolts it down don't match up - thanks

Mortech's website is also a reasonably good source too

My book shows it's off a 66/67 283/327 220, 275, 300 horsepower with Holley carb.

i guess a bigger question to ask is what carb am i looking for to fit this intake? like to keep as original as possible - thanks, Brent

Probably a 4150 600 cfm Holley. That manifold probably takes a square bore carb and not a spread bore like a QJet. Check Holley,s website. The have Calssic carbs listed.
