Side question, if I looked for a new Cam Shaft and Lifters for this 400 BB, what should I look at getting? I guess same would go for timing chain and gears.

Agreed, I was going to look into that next. Anybody have anyone they like around Chicago?? :)

Figured I would make a quick update. I was able to get my hands on NOS for a set of 3.21 gears for my 8.25 rear diff. I also was able to get a rebuild kit for all bearings and stuff. Now I just need to find that goofy square 5ft spanner tool. LOL!

Here is what I got and installed when I first got the car. I haven't had to change it in anyway and I set the timing based on the book and sound. https://www.amazon.com/gp/product/B000630IPI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Well, how about this? - 1973 CHRYSLER NEWPORT Motive Gear C8.25-321 Motive Gear Ring and Pinion Sets | Summit Racing 3.21 @ 8.25?

man people bought those so fast. I didn't even have a chance! LOL

Interesting. So I already have new short tube headers and all new dual exhaust. Already has a new tune up, I guess I could always curve the distrib as well. You think 2.71 GR is ok? As far as a Torque Converter, that seems like something I could and probably should to be honest as my rear...

No issues there, I had to keep testing and adjusting till I had it shifting correct when I change out the throttle and linkage.

Thanks Big John! This gives me some ideas!

That's some major advise there my friend. Thank you. Like you said, I am just looking for a bit more power off the line. Just to play. I am not looking to race anyone. I've already had the rear end out when I replaced the spring and shocks, so I was looking for an "easy" job that I might...

Sorry for all of these newbie questions all. Can I put higher gear ratio in my current 8 1/4?

Awesome info, thanks. Any advise on where I should look? Just look for a 8 3/4 rear end with at least 3.55GR? I would assume just look at some junk yards and just rebuild it?

I run 235/55/R17

I guess side question, if I wanted to change gear ratio to 3.23 or 3.55, do I need to change out the whole rear end or can I just change gears?

Those in that pic are 22"s but that was only for messing around. I normally run American Racing 17's, you can see in my other reply.

I already have duals with short tube headers running right now. Thanks for the info. I don't really do any open road driving, if I do, its short.

Hello everyone, Over this winter I am thinking about a project to do on my 73 Newport Custom. Its has a 400BB with a 4B Holley. It has the 3 speed 727 TF. My thoughts were around the rear end. Currently its the factory 8.25 rear diff at 2.71 GR. A few people have said that I should change...
