Just wanted to follow up on my previous post regarding vacuum leaks on my '78 F250. The 400 motor is now purring like a kitten with all of the vacuum leaks fixed. No more part-throttle surge or pinging on 87 octane. Thanks to all that helped!

I pulled my loaded 24' car trailer for the first time today for a short distance to see how the truck handled it. I must say that I am very impressed. Loaded trailer is probably around 8K lbs. The 400 took hills very well. Lost no speed on most hills and 2-3 mph on the tough ones. Granted we don't have major hills here. But it sure beats my 302.

Couldn't have gotten it running this well without the help here. Thanks!

 

So I should notify a moderator to merge this thread with the other one so everything is together ?

Glad it's going good for you now

 

Well thats good to hear im glad you got the 400 runnin smooth again
