adding a proform main body to a 650 dp

i run 1 on my 408 your 650 will be plenty for the 318 but a little fyi if u get the proform body as soon as u get it out of the box take carb bolts and base screws and chase the threads and it goes together sooo so much easier..so many haters on the proform main body but its a good piece but people need to do the right thoing and always chase the threads on new parts,,my 2 cents.. save ur cash and get a 360
