Does anyone know if anyone makes any aftermarket 4-bbl intake manifolds that will fit a 67 Skylark, 300ci engine? I ask because I want to put the intake manifold on my engine so I can put a 4-barrel carburetor on it instead of my old 2-barrel carb I have. Thanks for your time! Chris
No aftermarket intake is available. Stock cast iron 4v intake for a 300 was only available on '65 models. Not an easy intake to find and not really much of an improvement over your existing 2v setup. If you want to go faster get a bigger motor.
In 64 the 300 came with aluminum heads and an aluminum four barrel intake. The 64 heads only work with a 64 intake and vice versa. The 65 and later iron heads and the 65 four barrel intake are better than the the aluminum ones from the previous year. The Buick 300 can be built up to make more power but the limiting factor is the intake. If you have not read this article you really need to. http://www.hotrod.com/how-to/engine/hrdp-1103-how-to-hot-rod-any-engine/ Several years ago I scored a Buick 300 with the four barrel intake thinking I would build it for use in a hot rod. After doing a bit of research I decided to part it out. I got $500 for the intake. I'm told I sold below market.
Here's something maybe you can use..................http://chicago.craigslist.org/sox/pts/5048684017.html o No:
