I am swapping a 402 bb out of a 71 into my 69 which has a sb 350 in it. It has a TH350 trans. I have a few questions you guys might be able to help me with.
Do the mounts on the frame stay in the same place?
Can I use the same drive shaft?
Can I use the same starter?
will the oil pan clear the cross member?
will the trans crosmember stay in the same place?
Thanks for the info,
Tony
