Can anyone share their experiences with transplanting BB ('76 454) into a 70 C10?
We have already found that mounts are the first challenge and are trying to decide if we should go with the stock BB bolt through setup (larger perch hole) or use a 73 style (clamshell?). Any feedback would be helpful.
Other unknowns are
  1. firewall clearance for HEI distributor
  2. are there rad/fan clearance issues?
  3. Best header brand fitment. What have you used?
Any and all experiences are welcome.
