I am around three ProFlites (two from A1 one from Joels,) and all of them are stock case, its the only option. FWIW they are used in cars with over 1000hp and so far knock on wood no issues. As for adapting them to other applications there are a few ways. I like the A1 adapter best myself. There was a truck pull guy working on an aftermarket case but it was HUGE and heavy not sure if it ever came to fruition.

I can understand using something like that when it comes to Class racing, and a 727 case is required, but in a Bracket car, I see no reason it's a better option? How much does a trans like that cost? Seems like no one wants to say...
I've been told by Super Stock guys to budget $6-8k for a Proflite. Used ones seem to go for $3500-5k. At the same time, I was also privy to a conversation where a Mopar S/S racer claimed to have $30k in switching over from a 727 to a Liberty. As far as the SFI case, I never heard anything more about it either. I believe the truck puller who was doing them was from Missouri or thereabout? I'm not sure if any were ever cast, but there were CAD drawings for them. It was definitely investigated.

I can guarantee it doesn't cost 30K to install a Liberty in a car. Weighing out my options, and a well built TH400 was $3500 more then a Liberty, after adding every single thing up.

I saw a post on F.book a while back from the truck puller guys that were going to have SFI cases for the torqueflites built, said it was DOA due to the company they were going to get the cases from had been contacting many transmission companies also trying to get someone to bite, so they dropped it.
A Lot of us would love to get an SFI case, I have a lot of good parts that would really like a stronger case around them .... we have a few cars with up to 1400 hp behind them, with no real breakage,
but yes... there needs to be a stronger SFI case made.

This is where going to PRI makes a difference. I talked with a manufacturer of SFI trans cases, and asked if they had any plans to build a SFI case 727. They told me I was the first one to ask about it. People can talk about them all they want, but face to face time with the companies that actually make stuff is where it's at. That question needs to be asked over and over.

I seem to recall that the case guy was in contact with Keith Long. Part of the reason it fell apart was the guy couldn't find a foundry in the US that would work with the small volume this guy wanted.

Would a 727 case from a diesel application be a possibility? Guys have been running some serious torque through these I believe, and torque is what breaks things.
