904 for Towing?
You can make that lighter governor piston out of your stock one. Take 3/32 out of the center The more weight you remove the higher the rpm it shifts when flat out.
The Governor is the ticket for in drive street racing though. I had one that shifted on its own at 7200 You better have a good motor that twists up or it won't shift if you take to much out of a governor.
A factory 340 light weight governor shifts at around 6000. Perfect for a stock 444 lift cam. I put a 68 4spd. 455 lift cam motor, One year only 4spd cam. In a automatic swinger. I made that one shift at 6500. Auto on column leave it in drive and just plant the throttle. That car was a blast. Left arm out the door right hand on the wheel. lean back and enjoy the tire breaking pull.
Factory stall converter in a 340 is 3000. A weak motor will brake stall at 2800. If you got your **** together on a tuned stock 340 motor you can get it to brake stall at 3200 ish. I found the best street gear for a 340 auto was 323's, 355's were a tad to low. 355's are a good gear for a 4spd. car . 323's it is a little harder pulling out . The tires I used on all my cars were L60x15 same as 27560's
Towing converters in a truck are low stall 2200. They don't work for **** once you go beyond an RV cam and even then they sucked' Guys see the sticker they have on them and they think the have a good converter. I toss the in the dumpster
My tow vehicle gas truck I had a stock 727 3000 stock 340 stall converter, A part throttle kick. 465 lift cam with a dyer's 671 blower and two 7500's. That truck would pull a house. The trans was fresh and yes it did have throttle pressure . Look close at the pictures you'll see it. That was an every day tow vehicle. You would not believe the heads it turned when people would see and hear it pull in with a trailer hooked to it.
. We turned that truck into a 2003 common rail. We were always were looking for more power . That trans is still sitting in the trailer. Heat is what ruins a trans . A good trans cooler is what you need in 71 the 904's in the taxi Coronet's had it all they were a drop in performance 904. That blower off my truck I believe is on someones yellow duster on this site
So what I am telling you if that 727 took what I put it through for a couple years you won't have a problem with a stock 904 with the mods I mentioned. My truck had 37 inch tires 410 dana 60's. We Painted it two tone silver when we put the common rail in it. That was the color of the diesel cab we needed for emission exempt.
