The RFE just uses 1-8 (may go up from there but 8 is the highest chrysler trans I recall). In my training I have never been told that the number has anything to do with an actual torque just 1 is weak and it gets stronger and stronger as you go up the list to the heavy duty 68RFE.
So what does a torque rating of 5 equate to in ft/lbs?

Re: Hydrolocked hemi what should I do?

It doesn't that is what I am saying, I personally have never heard of a breakdown regarding torque handling and that is with Chrysler training on the topic, its a made up number that just means heavy duty or weaksauce.

So basically its just an arbitrary number, Gotchya. I guess than we will just have to push it and see what happens.

Re: Hydrolocked hemi what should I do?

I follwed the link to the Arrington short block listed at $5,000. At five grand, isn't the OP a long long way from done? Doesn't he need a lot of forged bits in the top end to go with all the boom in the lower half? Looking further on Arrington, that same engine completely built lists for $15,000. How does that fit into ten grand?

It's nice to dream with other people's money, but if the OP has access to ten grand and that's it, he should go to the junk yard and get a serviceable motor and keep dreaming of hot rods. Better yet, he can start rebuilding his old motor one bit at a time, while he drives around in a WORKING automobile.

Pushrods and springs are not 10 grand. A full short block setup plus everything required using stock heads will be around 6-6.5 grand.

Re: Hydrolocked hemi what should I do?

FWIW in the conversation:
The first number of the Chrysler built transmission is the number of forward gears. The second number indicates power that it can handle on a scale of 1-8 as mentioned before. The first letter is "R" for RWD applications with the "FE" standing for fully electronic.

The catch with the 545RFE is that it has 5 forwards gears available, 4 used consecutively, and one passing gear = 2nd prime. The Dodge Ram guys put huge power through the 545RFE with success.
