Olaf,

A far as price goes, that sounds like a very good deal, but check the reputation of the builder before turning over your rare and expensive sideoiler block to him.

As far as a roller cam goes, the biggest problem with running a solid roller on the street is short valvespring life.
Due to the extra weight of the lifters and the extremely fast opening and closing rate of most roller cam profiles, they require very high spring rates and high end (ie: expensive) valvetrain components. They generate a lot of heat and fatigue in the springs, which results in their weakening and failure.

The late model factory roller stuff has very mild profiles and hydraulic roller lifters, but there's little performance gain with them either.

I went with a flat tappet cam from Ultradyne and lightweight shell lifters.

If you'd like, send me an email with the shop that gave you that price. I may be able to send them some business if they check out alright.

Thanks,
