Torque converter bolts??
I just ordered my new 4l80e trans and conversion kit. I also ordered all the needed hardware for the conversion. I will be running a 4l60e torque converter. (with the three bolts). Is the three bolts going to be strong enough??

I certainly wouldn't.......that's the only connection between the engine and transmission and I'm pretty certain that three 7/16" bolts aren't going to hold the power of a boosted motor very long

....I'd still be scared....but if Allen can do it maybe I'll look into a 4L60e converter (they're ALOT cheaper than a 4L80e converter)

I still have time to change my order, But I was told by sells at Speed Engineering, that three bolt would be fine. (they have a 800+hp car with 60e converter) I just wanted to hear some other thoughts on it.

1-7/16 grade 8 bolt has a shear strenth of 10680 lbf at the threads (http://www.hobson.com.au/class_8.htm), so I would think that the bolts would not be the issue. Most likely the flex plate would brake before the bolts, but I think with you power level, you would be fine with 3 bolts.
