I think that will work, just let Ken know you are running a 2004R trans.

The biggest factor in a re-build is a good cleaning. The number indicates that carb came on a 1976 Olds Nintey Eight 455 auto trans. Jets are #68 and rods #41 and it should work well just as is. http://www.newagemetal.com/pages/Oldsmobile/70-79/pages/70-79Oldsmobile0068_jpg.htm I would attempt a good cleaning without changing anything else. Don't drill or grind anything at all until you have tried it on your motor. Buy the Doug Roe book and study it to understand the concept of carburation. I'm not knocking the excellent re-builders at all, just trying to get another car guy on board with Q-jet restoration. It is a pleasant endeavor and very rewarding.

I will probly send it in to everyday performance soon. I hear alot of good things about them. So far everything I've done to this car hasn't been as "easy" as it should. After digging into One job it turns into another and another. Might be better off having someone rebuild it. The 403 isn't stock.

I do have a carb off a 87 442 that had a 307 in it that I could practice on first......

'87 is an electronic carb and I would avoid that. Find a $5 swap meet carb and have at it.

Save the secondary rods they are the same for all. That is how you accumulate parts. I can't use Chevy Q-jets so I strip them for all the parts and toss the Chevy float bowl. That way you will have an assortment of jets and metering rods for customizing your own. Once you see how to work on these they are very adaptable to any engine you can build.
