| | | GM Goodwrench 350 - best carb for this engine? | Joined: Oct 2011 Posts: 128 member | OP member Joined: Oct 2011 Posts: 128 | Hi! I have Chevy Van Beauville G30 1979, it was imported to Russia (yeah, I'm from Russia) in 2003. Shure, russian servicemans a little bit nasty, and after I got this van, I'm going to carefuly restore it. So, my new friend: At first, I want to replace old carb Rochester, but not sure what carburetor and intake I need for GM Goodwrench exactly - I think it's not stock engine or I'm not right? I hope, somebudy can help me in this case. Unfortunately, my english is not good now, and here in Russia I'm away from good information about American cars, so please excuise if I'm so stupid in this matter.

I would start by finding a factory service manual for it and finding all the details on the van, such as engine sizes, year, etc. From there the Chevy guys can recommend what works best. | | | Re: GM Goodwrench 350 - best carb for this engine? | Joined: Oct 2011 Posts: 128 member | OP member Joined: Oct 2011 Posts: 128 | Last owner told me that it's not original engine. Now I cant understand diffirence between Goodwrench 350 engine and stock 350 engine.
Now I looking for Holley carb and intake. | | | Re: GM Goodwrench 350 - best carb for this engine? | Joined: Jul 2006 Posts: 1,593 veteran | veteran Joined: Jul 2006 Posts: 1,593 | Welcome to the site - great looking Beauville you have...
a Goodwrench engine is a Factory GM replacement engine - so everything that was stock on the van (assuming it was a factory V8 van) will work on it...
a Rochester is a good carburetor, but can be a nightmare to work on if you don't know what you're doing...
putting on a performance intake or carburetor is something you'll have to consider what you want to use the van for... i put a Weiand 'Stealth' intake on my Goodwrench motor for my '84 Chevy G20 and I like it - I had it on another motor before... I also kept my quadrajet, but it desperately needs a rebuild...
good luck with yours...! | | | Re: GM Goodwrench 350 - best carb for this engine? | Joined: Aug 2008 Posts: 18,213 Likes: 2 Supreme Master | Supreme Master Joined: Aug 2008 Posts: 18,213 Likes: 2 | aboard

This is a very simple and maintenance free sertup. | | | Re: GM Goodwrench 350 - best carb for this engine? | Joined: Feb 2002 Posts: 32,696 Likes: 172 Old Timer | Old Timer Joined: Feb 2002 Posts: 32,696 Likes: 172 |

Goodwrench engine is stock engine or customized? The second question - about new intake. Is intake for Rochester fit for 4barrel Holley? Thanks for support! | | | Re: GM Goodwrench 350 - best carb for this engine? | Joined: Sep 2009 Posts: 1,051 old hand | old hand Joined: Sep 2009 Posts: 1,051 | The GM Goodwrench label likely means the original engine was replaced with a new engine purchased at a dealership rather than rebuilding the original engine.
Most all aftermarket intakes will use a square base carb. They are easily seen for obvious reasons, it is a square shape where the carb bolts to the intake. Intakes that accept Rochester carbs have a larger opening at the rear and smaller openings at the front. The Edelbrock Performer and a few other aftermarket intakes will accept a Holley square flange carb or a Rochester style carb. If the intake you choose has only a square base, it will only accept a Holley type carb but there are adapter plates which can be bolted to the intake which will allow it to accept a Rochester.
There is one exception, there used to be a Holley Spreadbore carb which would bolt directly to a Rochester style intake, I am not sure if they still make this style or not. If you are buying new, I doubt you will have any issues.
Make sure you get the linkage parts you need to properly hook your transmission cable back up to the carb or you could damage the transmission.
