Remanufactured Engine w/New Intake Manifold Possibility?


Recently, I installed a Remanufactured (OEM Specs) 305 cu. In. (5.0L) V-8 Engine (VIN "U", Rochester 2GC "2-BBL" Carburetor) in a 1977 Chevrolet Caprice Classic.

As is customary with Remanufactured Engines, a reconditioned Intake Manifold is not a part of the deal; and, so, after doing my own "reconditioning & clean-up" of the "original/OEM" Intake Manifold, I installed it on the Remanufactured Engine without incident.

However, after using the car for some time, I'm of the belief that the "original" Intake Manifold might be somewhat "defective" - i.E, it may have a small vacuum leak due to age & metal fatique (300,000 miles) - gauges indicate that.

In an attempt to replace this "defective/original" Intake Manifold, I've found that, outside of a rare chance that an Auto Wrecker has this part in "acceptable" condition, a more probable solution is to order a new applicable Intake Manifold from an Online Reseller.

A problem arises, though, in that, not only are the pickings sparse for an OEM/Stock Intake Manifold to fit my Chevy Small-Block 305 cu. In. V-8 Engine, but many, if not all, require a "4-Barrel" rather than a "2-Barrel" carburetor which I would prefer to continue using.

Finally, I'm hoping that this admittedly lengthy explanation of my Intake Manifold "issue" will solicit some response and/or advice from the 2CarPros. Com community that might help me find a suitable (New/OEM/Old) Intake Manifold for my 1977 Chevy Caprice "305" Engine - 2-BBL, preferably; 4-BBL, if there is no other reasonable alternative.

Thanks for you interest!

Do you
have the same problem?
