Yeah whoever said open a window a bit and feed it $100 bills until it's full isn't that far off! LOL! I just wish I started with a cleaner southern car instead of a rustbelt car I've owned and bracket raced since 1984.

There is supposedly one for sale locally which has nothing to do with me. Pat, now retired, was a big 904 proponent so it's possible he had some made by JW. The bolt pattern looks right, but can't say for sure.

I do have an issue with the trans occasionally getting loose on the adapter on the trans on the 904.
It was in a 440 Roadrunner stocker that I bought. I removed it before
I got bounced back then some years ago. Probably would not make a difference
any more but I will not to care to chance it anyhow!

There are adapters that we use in our bracket cars
but not NHRA approved (I do not think any are for Mopars).

Boy would that save us some money.
Well I think Cope just made a 727 SFI case-bell, why not a 904 case to big block bell? Maybe it is in the works since the bell is separate. No shield needed then! Then farther, make it so any PG or 400 vert could be used, endless possibilities right there. God I hate this spell check BS!

My understanding is that Cope has made a SFI approved 727 case with adapters for both big and small block Mopars.

I also believe that the 727 case will hold 904 guts, I think I read that.

I don't think he is actually selling them yet, still testing, but I would think soon.

An SFI 727 case that could use 904 parts would be a great thing IMO.
