Let's talk converters

[jamie2370]

In particular 200 metric stuff, 305 in a Malibu. Not positive what is in the car but I do have an ATI that I can't get them to identify for me but.... What does this combo need in real world experience. I am thinking an 8" with around 5600 flash? Am I thinking too loose? I feel like 1-2 shift should be 6100ish and maybe 6400 in 3rd? What is in it now goes 5000ish but it came out of a 350 69 camaro(more inches and HP) Will a 7" be a viable option on this combo? I know the converter companies can answer most of this but I am looking for real world data. Also rear gear is a 513(may go to 5.38) and trans is 275 low

My car is similar to yours, small engine and slower class, i shift close to 7k and finish at over 7k i have 4.88 with a 26 inch tire, i need to send out my convertor i am hoping they can get it to 6k on the flash but i don't know if that is possible because engine does not make much torque.

You are right on track with 5600.

Anyone have experience with a spragless converter? I'm looking at an 8 inch from Broader Performance and have that option. Car is a 68 Mustang 302 with N351 heads and C4. SS/CS legal but run in bracket. 4:29 gears (new gears) 26 in tire for now. Ran to 7000 really fast on it's only pass last year. Want to shift at 6000-6500.

How much will I pick up, do you reckon if I change to a sprag converter?

I have a 3200 lb 23 degree sbc 3.875 stroke 4.185 bore with a set of out of the box Brodix T1 heads, I did change the springs before bolting them on the engine. 10 x 28 bias tire. All steel roll up windows and chrome bumpers. It has been 1.27 60 ft and runs in the 5's 1/8. Powerglide transmission.

Torque converters are like Pro Stock carbs, you can have two identical, one is faster than the other.

This goes for sprag converters too.

I've had sprag converters in this car, one actually ran about the same et as my best spragless. Almost.
