    I am looking more into the 80 conversion...I saw that crossmember and the haness on that website....its a LOT cheaper for the crossmember than I thought....if I switched to the 80E what level do ya think would be enough?
    I keep thinking that if I got a level 5 4l70 it would last me a little over two years without breakage....and THEN I could step up to the 80E if it poops the bed after I go on my first deployment when I rotate over to sea duty and I can do the level 5 80E with a new driveshaft without breaking a sweat financially....I DO have the cash to do the conversion but if I did the 80E I would be tempted to put a 14 bolt in it and a new drive shaft so that I wouldn't have to even toutch the rear of the truck again....and after I did the 80E conversion I would have to hold off on that blower for a WHILE.....what do you guys think?
    What level 80E would be enough?
    Would the 14 bolt be worth it to step up to while I am making the tranny swap with the bigger driveshaft parts?
    Will the cal-tracs kit that I just bought work with the 14 bolt?

    You can do the 80e conversion for 1/2 of what an FLT lvl 5 costs.

    I gotta look into the conversion a little more man...but a rebuilt 80E WILL take the same punishment as a level 5 or 7 4L70 from them? If so thats the case then it seems like I was heading the worn direction with all of that trans stuff....any of you guys had your truck run SLOWER with an 80E instead of the 65 or 70? that first gear makes me think that 3.73's arrent gonna cover it once the 80 is in there....if I run 4.10's it might make up for it....but then it will be like my old SS trailblazer on the highway.....that fun in the sun 16mpg....HA HA

    A stock 80e is capable of holding 600 hp. It has a much larger rotating mass.
