I know it is not quite in the same league, but a guy here close to me has a 68 Bronco that he used to dirt drag and now has run in the mud races a couple times. It is a 289 with Boss 302 heads on it.
It was originally built back in the late 70's and has been updated since then. I hate to borrow the line from Dodge, but when you are sitting on a hillside at the fairgrounds and he starts it up, it sounds sweeeet.


what about a 289/271. I think maybe I have only seen one of them run in stock/ss. what is the factor on that engine? Probably a little high to make it a competitive combo?

I can't remember seeing a boss 429 either jltefft1.
