4R70w Torque Converter Recommendation

[theshadow]

Hey team -

Narrowing down TCs for my rebuild and was looking at the FTI Street Brawler 2400 stall, and the Hughes 53LXTM with 1800 stall.

The Hughes rep recommended the above after filling out their Tech Card, haven't talked to FTI yet. However, FTI doesn't have a lower stall that I see.

Anyone have good recommendations or experience with either? FTI seems to have a solid reputation with the Mustang crowd.

Motor is 347, P heads/custom cam.

No idea what you "custom cam" is

So I will just say use a stock Explorer convertor.

Lower stall choice...

For that powerband, stock Explorer convertor. Still my choice. Simple, cheap, lots of factory engineering.

PTC in Alabama, ask for Layne. They have built a few converters for me including the one for my 4r70w. So far they have all been spot on. They dont just pull one off the shelf that seems like it will be ok for your application, they discuss exactly what you have and what you are looking to do and build it according to your specs and wants.

Jay with Broader Performance in Weatherford TX has done 2 custom converters for me. One for a C4 and the other for a 4R70W and they were both exactly what I asked for. Highly recommended!! I went with a 1500 stall which I love with my cam and I would recommend around the same for your cam.
