rocketraider Posted June 8, 2002 Share Posted June 8, 2002 What's wrong with getting the original Rochester 4GC rebuilt? Kits are still available and there's still old-time carb guys around to fix 'em. Look in Hemmings Motor News magazine and you'll find them. There's a fellow currently advertising 4GC rebuilding service in Olds Club's <I>Journey With Olds</I> magazine and has some RB in stock ready to bolt on. I suggest joining OCA if for no other reason than the magazine has an all-Olds classified section.<P>The Edelbrock AFB will bolt right up to the 1965 425 intake but you'll have to fabricate a new fuel pump to carburetor line and may have to fiddle with the throttle linkage a bit to make it work. Stock Olds aircleaner probably won't fit well either.<P>I think an Edelbrock 600 is a bit undersized for an Olds big-block. They're fine for a Chevy.<P>Holley lists a rebuilt original 4GC carb for your car on their website. Link to comment Share on other sites More sharing options...
Guest Posted July 31, 2002 Share Posted July 31, 2002 Hi John!<BR>I have to suggest to only use an original rebuild Rochester! I´ve tested several Holleys and Edelbrocks on several cars. Even when they seem to work fine with seemingly little more power - after a while they ar starting running poor. No wonder - compared to the original Rochester they are a bulk of plastic.
