Cam & Timing Set Questions

To make the move from a FT cam to a SR cam is a big expense.
You basically need “everything”.
Cam, lifters, pushrods, springs, possibly rockers, oil pump drive gear, and many times a different timing set.

But, with either a HR or SR cam......the break-in woes aren’t an issue.

With the SR, for something that will see a lot of miles.....the lifter wheel bearing life becomes the concern.

As the spring loads go up, everything associated with that gets worked harder.
Not great for the crowd that wants to “set it and forget it”.

I don’t build engines for customers anymore, but if I did......a FT cam wouldn’t go into anything I built anymore.
