I have never done business with Bruce but used to see him at the POCI shows in So. Cal. I know about the topics and posts related to him as mentioned above. I even received an email from a guy talking about his problems, but I have no first hand knowledge. As stated above, there are many very reputable Pontiac engine builders.
My main concern with Bruce is his need to bash other Pontiac engine builders in print all the time. If you are that good, why do you have to bash someone else. Your work will speak for itself.
The Pontiac enthusiast population is fairly small compared to other makes and there are only a handful of good quality Pontiac engine builders. To me,there is no need to bash someone else in this Pontiac enthusiast market. Why bash reputable companies (read Butler) that are investing large sums of money to develop and help develop high quality engine parts to keep these Pontiac engines running.
