I sent my old 5180 stall converter to Transmission Specialties to have it upped to 5700-5800 stall today. I will also be changing my stock 1.76 low-gearset to a 1.98 straight-cut low gear in my powerglide. My 422 small block went 6.00@113.27 and 9.56@137.89 with a 1.32-1.34 60 foot with the 5300 stall converter that is in it now. Any guesses on how she will run when I switch it out in a few weeks. It feels like a snail leaving the line right now.

No guesses so far. I'm going to guess .12 pickup in the 1/4 mile with the solid lift cam that is in the engine now. Of coarse I would be VERY happy to see more.

What does the car weigh ? It's around 2750 now up from 2575 or so. I'm over 100 pounds heavier than my son that used to drive the car and I sold the fiberglass doors and went back to steel doors with wind up windows. Also added a few pounds with some other user friendly items

I'm not qualified to make a guess at your question, but your new low gear will reduce your stall speed slightly.

No guesses here but am interested to see how much your combo picks up with the gearset change. Keep us updated. I'm considering changing out the 176 gear in my glide to the 198.

I'm not qualified to make a guess at your question, but your new low gear will reduce your stall speed slightly. Transmission Specialties will have my convertor on Monday and cut it apart. They usually call the next day to discuss changes but he already said I was going in the right direction bumping it up to the 5700-5800 area. When I tell him about the gear change we shall see if that factors in.

Will the extra converter stall keep it from lugging the motor on the gear change?
We tried low gear sets with our little tiny motors and what we gained with a low gear set we gave back at the shift.

A 1.98 gear is still way high compared to a 3 speed. Years ago I tried a stock 1.82 powerglide gear behind one of my 440 engines and it was .08-.10 quicker. They are lighter and it only last 125 passes before I broke it. Never broke a set of 1.76 gears.

When I ran S/ST in my Challenger with a mild 440, I started out with a 1.96 low gear set in my Glide, and absolutely loved it. It broke after 275 runs, so I bought a 1.76. Rear Gear, and converter changes never gave me back the 60ft. I lost from that change, just never could compensate for it.

I'm curious to see what my car picks up this year,78 Plymouth arrow tube chassis car, 2560 with me in it, went 9.79 with a cheap 10" 4000 stall converter in my 904, put a ultimate 5500 stall 8" in this winter, so we will see in a couple weeks... I think you will love the results

Any clue to how much power you make.. but at your weight you should be easy is the 9.30s unless you have a big anchor in the car

I don't have any idea, The motor is a stock stroke 360, eddy heads ported by shady dell, ported victor 340 intake, custom racetec pop ups, I got 240 psi this last fall with the cylinder pressure gauge! 1050 dom running e98. 1 7/8 to 2" fender exit headers I built. Never have had a good converter in the car, the vert I put it in came out of my 70 dart with iron headed 360. so it wasn't anywhere close to what the Arrow is for weight or chassis. best 60 foot I ever got was a 1.32, no matter the up grades I did to the motor the 60 would pretty much stay the same. With the 1.32 your not way off.. if you have good parts i the engine you should e turning 8000 to 8500 rpm.. you have good cyl pressure.. do you know what the heads and the intake flow

The heads flow 290 at .600, not sure what the intake flows, shifting at 7000 right now crossing at 7300 ish, solid flat tappet cam, 642 on intake 652 on exh. 292 duration, I only had Ryan do a stage 2 on the heads, What does your conv stall at now.. I think you said its a trans brake now.. pull the chip on the revs ans see what your max stall is now
