I called edelbrock today for tech help. they suggested part number 1459 for the metering rod and part number 1424 for jet. I put new plugs and going to run boat to check plugs, but I think its running rich.

I'm sure this is another one of those subjects that everyone has an opinion on so here is mine. It seams with the DD (mine is bone stock) everyone seems to want to over carburator them. I have small 2 barrel Rodchester off of a late 60 oldsmobile and it runs great, has good snap and super fuel efficient, 15-20 gal all weekend. The only problem with mine is it has a small bobble when first pushing the peddle down due to the small accelerator pump. I had a around a 650 edelbrock on the boat before and it was running way to fat. I have a friend running a 4 barrel edelbrock and he has issues getting his to idle down once it is hot. So my 2 cents would be to start small and work your way up. The small block DD don't require much fuel to run so you don't need much carb. Mike aka Gasforblood has a 4 barrel on his and his runs pretty good you could send him a message.
Hope this helps,

I used to race is superstock nostalgia ( 67 gto with two afb on top @ 600hp) which was required to run a Carter AFB
Which is the same as in Edelbrock carburetor
I have purchased jet kits Rod kits spring kits you name it from Edelbrock
I swear to you it seems as if just changing out the springs makes the largest difference with the stop rods

The key is figuring out what springs work with the vacuum curve kind of like a power valve on a Holley finding the right springs will create a very clean crisp engine with great throttle response

With this carburator it is very hard to over fuel or enrich the fuel system once you are over the Idol circuit
As with a metering rod system fuel can only be added as the demand of the engine can take it

This springs only change how soon the enrichment occurs
The rods control how rich the fuel is

The stock carb can safley support 400 hp all day long
As long as your pump can keep up with the flow requirements

I had a two barrel rodchester on there, ran it for the last 2years. I just put the edelbrock on same results (may idle better because its new carb). The long and the short of it, is a 600 is more carb that is needed , but I was told that you can tune it and hopefully we can pick up some rpms on the top end. Maybe

i have 350 dd on 14 rivermaster. ran 750 eldo for several years. it always ran just a little rich but not to bad. in autozone a while back and saw 600 eldo for good price. it no longer runs rich and idles good out of the box. is it to much carb for it i dont know but i am happy with it so for my boat i guess it is just right.

670 Holley tuned by s&s performance carburetor. Money we'll spent. Haven't looked back since!

The difference is that he is asking about a DD, and you are running a gearbox; BIG rpm difference.

Yes, a 600 is to big for a 350 DD to be optimal.

It could be tuned to run acceptably, but that is way more than is required at DD rpms,
and will use more gas to make less power than one that is properly sized.

There are more than a couple better options. This thread has the info you're after:

I use that rod when I also change the jet size to part number 1426. If Idon't change the jet I use rod number 1449 with the stock jet. Its worred well for me to richen up. Not sure about your area but the Pep Boys by me carries the tune kits. Good luck and please post what works for you.
