4l80 vs 4l65
Okay, I'm going to try this from a different direction. Given that I'm hoping to make around 500 (450 easily) at the flywheel and the trans is going in a 68 firebird behind an ls2 that was a stick and that transmissions are voodoo to me which way should I go? I need to know if one or both can handle it and which fits better. I've actually read the 80 fits with minimal massaging where the 60 series needs a bit of work but I've also read the opposite. Which is true? The 80 weighs more - how much more with the fluid and convertor in it is still open for debate. Is the power capability worth the parasitic loss at my level of hp? If you have one in your car I would really like to hear from you.
thanks
Scott
