It's not necessarily unusual to use a single weight for break-in. However, after that I'd be running a multi-weight. Talk to your builder and get his recommendation. In general you'd want to run a lighter multi-weight (10W-30, etc) so you get quicker flow at start up. The only reason I can think of for thicker oil on a street car is if your builder left the clearances on the large side.
Good luck.
