ok now looking at that motor, im planning on buying an 86 monte carlo ss, and i want to buy and put that motor in it, now my question is this i heard the stock tranny will be ok for that motor, is that true? also there are some parts mentioned on that link that i need to buy or screw on to the motor...do i have to buy those parts new? or are they in the car stock, and i can just swap the parts from the stock monte motor to the new motor? is that possible or must i buy those parts new?
