Hello, I have a 1986 Monte Carlo that im doing a 305 to 350 out of a Cutlas. Would i need to use the drive shaft from the Cutlas, and what else will be different or problomatic on this swap?

 

what year is the cutlass ? just make sure that it is not a olds 350 . as its not the same as a chev350 . if we are taking about 2 chevys here it is as simple of taking out the 305 and replacing it with the 350.
now if its a rocket motor then it gets more involved
