I'm looking to upgrade my 1972 350 oldsmobile engine from two barrel to four barrel, went to salvage yard found a 1983 Buick Electra Vin Y 307 oldsmobile engine will this four barrel intake fit correctly on my 1972 350, the numbers on that intake are 22503087 the one that I currently have is part number 410670 please any help on this manifolds will b appreciated, I currently have 7a heads on my 1972

 

If I'm not mistaken, the ports on the later model manifold are much smaller and restrictive. Hopefully one of the other guys will chime in and give you some better insight.

 

I think you can find an Edelbrock for cheap, used. Maybe on this board. Much better than that factory restrictive piece.

 

I found some data apparentlty i need the 22504086 which Is the a4 intake, or like z11375ss said the edelbrock intake

 

Throw out a looking for. You may find what you need.

 

usually 100 bucks or so in good used shape cant go wrong with the performer.

 

If you can get an A4 intake for under $25, it's an acceptable 4bbl for the street. The A5, however, has the tiny ports that match to the 7A heads. Avoid that one at all costs. A used Ebrock would be a better choice if you can find one. Depending on how long you want to look, you can often get one for under $100.

 

I'll ad you can always paint an ebrock engine color to hide the fact also.

 

Even better, if you're going for the stealth look, is to carefully grid off the E-brock logo then glass bead the intake to hide the grinding marks prior to painting.

 

It should, if the motor is stock in that 83 have either a normal sized #17 iron intake or A4 aluminum intake. As long as it is cheap, it will work fine. You will need a non CCC Qjet as that 83's stock carb will run pig rich without the computer controlling it.
