Converter. Trans brake questions.

Lenny is awesome! You won’t be disappointed. He’s getting ready to build me another one for my new combo.

I agree!
I haven't drove my new converter on the street but maybe this will help.
I had a factory tq that was tweaked to stall at 2800 rpm with a 340. Same converter stalled at 3000 in my 408.

Called Lenny and he suggested that i get a 4200 rpm converter(I shift at 5800 rpm in my 408)
I have a MRVB only NO brake. I have a 2 step that i use solely to turn on a light at 2200 rpm. That is were i stall my eng at, at the starting line. The new TQ gave me a better 60 foot, ET and less rpm(less converter slip) at the top end.

When i got my new converter installed, it took more throttle to stall at that same 2200 rpm but when i launched, she went way past 3000 rpm and climbed all the way to 4200. And pulled a LOT harder.

Question, What cam and compression are you running in your 360?

Question #2 When you put you MRVB in 3 gear, and mash the brake, and
throttle wide open, what rpm do you get.

Also Lenny converter is only going to be as good as your data.
Would be good to have a 1/4 or even 1/8 mile et slip. To give him more data of your build and how he need to build you TQ. Just a Thought.
