i read it as he has the v8kmember and a 318 and whants to put a 360 where the 318 is right now, i gues there is mounts for this but on you are on the cheap the only diferens betwen a 318 and a 360 is that the ears on the 360 is alitle closer to each other and that can be solved with just a few washers or a a flat piece of metal that is the right thicknes..
i run a 340 with 318 mounts i have the newer k member with spoolmounts and i just put a nut as a spacer in my driversidemount, it may not be right but its the simplest and cheapest way and honestly i just did what i had to to to get the engine in that late night....
its only the driverside that is diferent
