I strongly suggest that you don't use Scott's! I have built hundreds of engines over the years (race, mild, stock, etc...) and tried using them at one point, but they couldn't seem to do **** right. That was a few years ago. I even gave them another chance about 8 months ago, but they ****ed that up too. There are a bunch of morons running that place. The only one that I can say I am happy with is Proline in woodstock. They are very well known across the country.
