How can i find out what an intake is off of? I have the numbers off of it! help!
 

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

just do a search for g.m. casting numbers on the web.....
9157 sites come up..... :D

Mortech's website is also a reasonably good source too

intake
 

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

intake numbers
 

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

carb
 

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.
