Jim - I'm ready to pull the trigger - PM sent!
Any 4L80E converters?
I had 2 chances to test the theories concerning converters for stockers. It was all good!
1. My 1965 GS 401 had a switch pitch TH 300 automatic 2 speed and it was really holding back any performance with the 401 engine (high 15's in the quarter).
So I installed a 3.55 posi rear gear, TH400 transmission & kept the small 300 switch pitch converter (about 3000 stall).
At the track, great launches and mid 14's. on a engine with 90,000 miles on it. Had A/C, PS, PB and all stock engine. Well over a second improvement at the track.
2. My 67 Skylark had a 340 engine and TH300 2 speed. I installed a TH400 switch pitch and the small 300 converter. That car was so much fun to drive.
SOOO-- My opinion is that a 3000 stall converter is a fun addition on any car that you enjoy driving. Just get a good one that is not sloppy. Good converters ( like JW's) drive like stockers, but add some fun when you hit the throttle. You won't regret it. IT won't suck up all your gas either, but YOU WILL!
Note. Think about it....Buick was the first one to develop and produce higher stall converters long before anyone else. You ever heard of a Dynaflow, or how about "switch pitch" Dynaflow. Yes. With less than 200 HP? yes.
Yes, Tom, we have a 9.5" based 4L80E converter, in both lockup and non lockup configurations.
Jim, what’s the price for the lock up converter?
$779 plus $40 shipping
Triple disc Kevlar lockup clutch in Billet end housing.
Jim - did you get my PM?
Thanks Jim, that’s a good price. I’ll PM you
