A-727 TF race mod reversal

[7T2FISH]

Good evening group. I'm working with a 727 torque flight. It is a true race transmission from Bob Mazzalini Racing in San Bernardino, Ca. Here is the question the trans was built to go behind a 1000+hp Hemi. It now is going into a 514cid 440. I am not using the billet converter the stall speed is too high for the street. My question is this, the 5800 rpm governor counter weight, should I keep it with a 3500rpm stall converter? Or go back to a 340 6pk slap stick trans counter weight? The drive was awsome and a few Hellcats got exorcisms but at 6 miles to the gallon I am done.

Contact Bob and find out if there any other mods to be aware of before you make changes.

Good advice above - call the guy who built the transmission.

Bob will help you and make suggestions if you tell him what you want to do with the transmission!

Fellow Mopar Nuts, Bob was the first call I made before posting. He was able to tell me who built it for him; however, he has past away. And with his passing all the technical information is gone. Since this posting, I able to get the information needed to "un-mod" the trans and learned a few new things in the process.

That's very sad to hear about Bob Mazzalini passing. He was a great and generous man.

 

[Steve340]

He means the guy who did the transmission died - not Bob.

Thank you for the correction. I was worried there!

I didn't think the governor did anything on a manual valve body, I removed it on mine when I put in a H/D O/P shaft.
