The most economical option, easy to tune and maintain, with more go when you need it. It's uniqueness gives it sex appeal at the curb too. | | | | | Joined: Oct 2001 Posts: 3,458 Extreme Gabster | | Extreme Gabster Joined: Oct 2001 Posts: 3,458 | If you are looking for more of a stock appearance than the 2bbl manifold from a 302 will work as well- the early ones fit the 3-bolt Stromberg/Holley pattern, and the later ones fit the 4-bolt GM Rochester 2GC pattern.

Patrick's also has a 4bbl intake for '270 and '302 gmc engines and 390 carb is perfect! We have had great success with this combination and Fenton Headers! which also look beautiful with the Jet Hot coating! The gmc engines run really strong with the 4bbl altho the 5 carb looks more nostalgic.whichever way you go,I hope you have a cam to handle the extra carburetion? I would recommend around a 264 or an F290 grind for you. thanks,phillip | | |
