I agree with the fact that the powerglide robs ahelluva lot less power. But as far as weight goes, Theres only about 25lbs difference between the th350 and powerglide. plus usually, and I mean USUALLY, the turbo 350's are cheaper to build. I personally like the idea of shifting only once and like them both. As far as a th400, Well the cost too much to buy and build compared to the other two. They are very tough out of the box but do rob alot of power. Like 45hp in stock form. Given building it up will make that number decrease but a th350 usually robs between 25-35hp in stock form and the good ol shlushbox er, uh, powerglide robs even less. So if you do themath it's a no brainer. But I think kevins a cheap ass. JK!

How much more does this tranny weigh compare to the stock AWD transmission?
-
Dave just breaks trannys so he has a bunch laying around.
I'd really be interested in knowing how much my auto trans weighs, all I know is I can lift it and set it down a few feet away but that takes almost everything I have in me.

Powerglide is lighter, takes less power to turn, Same price to build (check www.summitracing.com or www.jegs.com), for most 4G63 use...won't need any building at all and honestly.....do you really think that a 4G63 can ever make enough torque to blow up a PG? The powerglide is behind many 2000+ V8s that produce over 1200-1500ft lbs of torque. The powerglide is actually stronger due to the less gearing, larger shafts, etc. The ONLY advantage to using a TH350 is the 3rd gear. But....that 3rd gear is a very tall gear. Mighty Mouse (Buschur's old car) tried running a TH350 in his RWD and could never muster better than a 10.3x. Switched to a powerglide and now run's mid 9's all day long W/O NOS.

I wouldnt build any tranny to hold up to the power as much as making it better between shifts. Building it up persay makes it more efficient and also decreases it's power consumption. So leaving any tranny stock is foolish. Ask Dave H. with 600 or so whp if he would put a non built trans in his car or just take a stocker and throw in a shift kit or a manual valve body. Remember that kevin's also pushin over 500whp. at least he was last time I checked. I know that torque is the big killing factor on most trannys but his torque numbers were pretty respectale too. Comparable to a decently built V8. And I would probably be safe in assuming he's got more up his sleave for this build. Just my 2 cents.

Just my 2 cents.Kevin's car actually was just a little over 400WHP last time he was on the dyno. But as far as I know he has sold a bunch of parts in order to go bigger and better, so we should see some bigger numbers next summer. Well, assuming that his RWD project actually works! j/k Alien, I have faith in you.

I'm sure Kevin plans on building the tranny up, it really doesn't cost much. $1000 in parts and $100 for assembly is what mine cost... and it should tolerate a lot. Also, my car is around 710-720 whp now, based on HP calculators (9.46 @ 143mph 3100lb)
