What are the original carburetors and intake manifolds used on RQA 327 300hp engines? Height is an Issue.

What are the original carburetors and intake manifolds used on RQA 327 300hp engines? Height and ORIGINAL numbers are Important. Were Carters original equipment? How about a low profile intake manifold? I have seen Early RQA's with a Studebaker Avanti style air cleaner but don't know what carb its on (4 7/32 neck) ?

    Thanks RQA 217

My '66 has the 327/300 motor.  The number on the intake manifold immediately behind the carburetor is 3872783; immediately under that is GM2.  The number immediately in front of the distributor is J185.  The carburetor is a Holley 4160.

I don't believe the 327 was still manufactured in '78. GM was making the 350 by this time; perhaps Avanti Motors bought a bunch some years earlier and was still using them in '78 -- I don't know.  The 327/300 had 2 'humps' on the front of the cylinder heads, one on each side; they were called 'Camel Hump' heads.

Hope this helps.  Good luck.

Avanti Motors went to the 350 engine in 1970 with the start of the RQ-B series.  The last few RQ-A models would still have used the 327.  But...as already said...there could have been some unused until much later.  

The intake would likely have been what was standard on a Corvette of that year.
