What would be some possible problems that I will run into by swapping an '86 350 thats currently mated to a SM465 into an '84 K5 that has a 305/700r4? I'm keeping the 700r4. would there be any problems as far as parts not matching up, 'cause I thought that I had heard somewhere that swapping motors newer than 85 into 84 and older would not be just a basic switch, is that true? I would really like to get that 305 outta there soon!! thanks Know any GOOD Wheelin' in Northwest Jersey, let me know?
