A833OD inspection results... thoughts?
Well, that's an issue. It's aluminum and I plan to beat on it a little bit. During the summer my Barracuda is my daily driver, and also one of my main sources of entertainment. It's not a race car, it just has a stock compression 360 with an edelbrock street cam, low-rise dual plane offenhauser, long-tube headers, and a holley 650. I think it'll stand up to what I plan on using it for, but I also know that the aluminum units are known for being weaker. I'll call a machine shop and see what they would charge.
At your power level I think I would let it slide.
8/1 compression is easy on parts, as are the Edelbrock cams.And the Edelbrock plus stock compression together is yet easier on the drive-line.If you installed the 2177 you will have no problems with the cluster pin. That cam has specs of 270/270/110+4, so the ICA works out to 61*. Couple that with an 8/1 360 and you come up with a cylinder pressure around 125psi@ sealevel, which will be ultra easy on parts.
For you, that aluminum case that you have is stronger than it needs to be,lol; the case will not be a weak point.

What Chrysler did was to make the cluster pin float in the case at the front. The hole is several thou bigger than the pin. That area fills up with oil and is said to damp cluster rattle to make your driving experience quieter. I guess it does that cuz I never heard the racket.
What I discovered tho at my power level, and 11.3 compression ratio,and using 50% ATF, is that the constant apply and release of the power IMO slams that pin around pretty good, "wallering" out the hole. I can't prove that this is what caused the demise of my input gear, but you can imagine that as the cluster gear moves away from the input, the tooth loading climbs away from the root of the teeth and up closer to the tips. In any case Zing! I lost all the teeth up front there. I took it to a machine shop, had them bore the hole round, fabricate and install a light pressfit slug it in there, and then bore a new hole, finish-reamed to be a light press-fit also, to the pin.I never broke another gear after that.
Eventually I got me one of those Passon Performance empty aluminum cases, and never gave the gear-train any thought after that.
Now I have to tell you that I ran a GVOD behind that OEM case , and a CFII clutch.And I wired the GV to be a splitter. I shifted that puppy with the pedal to the metal at WOT and a little north of 400HP. It's violent enough to break the 325/50-15 BFG-DRs loose at over 80 mph, with my street suspension. So that's being pretty abusive I guess. That CFII broke a lot of parts until I "wised-up" and got rid of it. It's way more clutch than a streeter needs.But I didn't know that before I bought it,lol.
