I have a 91 RS w/ 305TBI 5spd. I want to swap in a freshly rebuilt 350 w/ 600 carb. I want to use it for the street and the strip.
How hard will it be to keep the AC and hook it to the 350?
Am I better off getting rid of the stock 5spd, will a 6spd from a 4th gen fit? If I change trans, will the driveshaft fit?
Can I use the stock electronic fuel pump or should I go with mechanical?

 

As far as the AC goes....when I swapped a 350 in mine, I didn't even have to crack the AC system open. I just took the compressor off the bracket and wire tied it to the fender cause the AC lines are flexible, so that was a sinch. The AC bracket "should" bolt to the 350 the same way as the 305 (Beautiful thing about SBC).

And for the trans...what year motor are you looking to put in? If it is a pre 86 then you'll need a new flywheel that fits a 2 peice rear main crank. And if you decide to put in a six speed, your driveshaft will fit as long as it is out of an F-body car cause the aftermarket T56's need a shorter driveshaft. There are a few other things that's you'll need to know about putting in a T56 but there is PLENTY of info on this board if you do a search for it.
