Eric, I'm not sure I understand how a new lightweight hi-perf driveshaft is only rated for 4000rpm. I'm sure I&quot;m missing something.

That is terrible carnage. I never would have imagined that failure would have torn the trans off the bell!

I want to keep a stick in it if at all possible, but after this incident, whatever goes back in the car will be as bullet-proof as I can afford to make it. I have a few manual trans options I'm considering, I'll just have to wait to see how things shake out over the next week or two.

I checked the Quicktime (now owned by Lakewood) website and it appears they do offer a repair &amp; re-certification service for their bellhousings, so hopefully I don't have to throw this one on the scrap pile along with the trans &amp; driveshaft.

It wasn't a high performance drive shaft, it was a stock replacement unit.

Look over this chart, it explains everything. It all has to do with length, tube diameter and material:

(My driveshaft was 60&quot; and 3&quot; mild steel tube)

I have decided one thing for certain--even if it means cutting/altering the driveshaft tunnel, the car <span style="font-weight: bold">will</span> have a 4&quot; drive shaft in it this time.

This is about how I feel right now.

I bought this for my Nova when I went back to a Muncie. Real nice piece and great people to deal with. A driveline vibration disappeared after this (not that my car does not have enough vibrations due to solid mounts)
This was $467 to my door in 2013. It is a 3.5&quot; by 54.75&quot;. The 3.5 inch is tight in the tunnel, but doable.

Aluminum?

Re: Well, the Chevelle is D.O.A.....
 

Yes it is

Re: Well, the Chevelle is D.O.A.....
 

Eric, really sorry to hear about the mishap. I had something similar happen to me going about 100 mph when the trans tailshaft grenaded. I'm all for more HP, but for only a 25 HP loss on a non competition car, I think it seems more practical to go back to the stock oil pan. LOTS of hipo engines running just fine with a stock pan and that eliminates the needs for expensive and custom driveshaft and all the other issues.

Re: Well, the Chevelle is D.O.A.....
 

It wasn't just 25 HP, it also resolved a serious windage issue which was causing oil pressure to drop rapidly above 5500 rpm. These 4.25&quot;+ stroke cranks open up a whole `nother can of worms when it comes to oil control.

I'm considering picking up another identical Milodon pan and reducing the front sump depth by ~1/2&quot; which would allow the engine to sit at OEM height.
