Update: Did the HEI conversion recently to the 351. Have a couple question for guys that have made the swap...
1) Where did you pull your vacuum from? I ran mine to the back of the original WW carburetor. (Same spot the vac was on the 305 in my pickup).
2) What degree did you set your base timing at (vacuum line unplugged)
3) When you hold a timing light on the engine, does the mark steadily increase, or does it jump up suddenly at around 1000RPM's?
Truck definitely starts faster! Still having power issues, gets a little better as I increase the base timing (now at 10deg). Not knocking yet, but I don't want to get much higher than that. Have a feeling vacuum advance plays a part in what's going on...
