whats rear does the donor have? maybe i missed it.. 3.42 LSD behind a 400 sounds pretty mean off the line.

Re: 1988 400 sbc swap
being an rs i doubt its a posi. and its more than likely a 2.73 gear. is your 3.42 a posi?
Re: 1988 400 sbc swap
its the stock rear for an 88 v6 car.. not sure .. I only say its a 3.42 because all the info says thats the only gear ratio available in the v6 cars in 88.. I have a few other projects that im finishing up so i havent really dove into this one yet just rounding up parts ..

ahh ic. well id just see what you got before you start gettin other stuff. if indeed its a 3.42 posi rear end then its the best rear that came with these cars besides the 9 bolt.
