It’s been years since I ran a solid roller on the street. But when I did the standard week end was over 200 miles. I didn’t own a trailer and the town I street raced in was 40 miles away. A lot of the time we would go on Friday and Saturday night. That was 160 miles to get there and get home, not counting cruising or racing once we got there. I put 1000’s of miles on that engine. Broke one tie bar in all those miles. It had one thing that I think is a very good idea. The engine had a rev kit. Basically an extra set of springs that kept the slack out of the lifters. This was in the 70’s so I would think lifters are much better now than then.
