4bt 72 Dart

Wow....good info! Thanks. I haven't pulled the trigger on the truck yet, but if I don't..... I likely won't ever find another one in as good of shape as this one. I apologize for side tracking the thread. DukeBoy sounds like he knows his stuff about these engines, and you do too. Thanks to both of y'all for the info. :)
No problem. I've worked on these engines for over 20 years, as a hobby and a job.

If you have any questions, let me know, glad to help.
