How hard would it be to drop a Grand National Motor into a 1985 Buick Lesabre?

I understand that anything is possible these days with automobiles. But I wanted to know what would I have to do (beef up, brace, change over, etc...) if I wanted to put a Grand National Motor into a 1985 Buick Lesabre? Just something different I was thinking about doing. Would the motor bolt right up? What kind of tranmission would I need? Please feel free to elaborate.|||not hard you can drop anything into a buick lesabre|||it should be real easy. it should bolt right up. you wouldn't have to beef up anything.|||would think it should be a pretty easy swap. G/N motor is a 3.8, same as what some Lesabres probably had. I'd think you'd probably want a 700R4 tranny (if it didn't already have it in it already....)|||you have to take off the whole exhaust system, have a engine hoist so you can take out the current engine without your transmission falling right off and you need a transmission jack, then pull out the transmission and then take out the current engine if there is one...|||It should bolt in since the GrandNash platform was similar to the LeSabre then. You may need to find more room for the turbos in the LeSabre, but it should'nt be a big problem. The GrandNash's were all V-6, but a V-8 (not even close to the power of the Nash's 6) was available in the LeSabre. That should'nt be a problem either though.
