    Hey guys, i'm looking to swap a zf 6 speed from the lt4 vettes into my 79z and bolt it up to my 327. is this any more difficult than a typical tranny swap? anybody done it? i can find the zfs for pretty cheap and they seem to have a good reputation around them but i dont wanna just grab it and not be able to bolt it up. suggestions help thanks.

    The T56 is a big trans too. Check the trans forum for some other users' swaps.

    I can vouch for the T56 being heavy......

    I toted that thing about a couple hundred feet by the input shaft and the tail shaft while it was raining(so I was going as quickly as I could) across my yard and down the basement steps and sat it on two cinder blocks and I thought my arms would fall off before I could get it set down.....don't even have a guess at the weight, but I'm betting it is over a 125# easily....

    Good guess John. TTC lists the weight at 122 lbs. Not sure if that's with the bellhousing and shifter tho....:)

    So how much more is that than a turbo 350,400 or a manual set up? At least the weight transfer is so close to the middle of the car that it should equal out quite a bit.

    Rob I used to hold my BW T-10 up with one hand, laying on my back, under my Corvette while reaching for wrenches with the other hand, so I'd say that there is a considerable difference in weight between those two trannys.
