stock 318 cam specs

My motor is a stock 88 318. I would love to put a cam in it, but for a $1,000 it is a bit out of the budget. From what I am seeing, a performance regrind on a roller does not exist?
As a kid I worked at a machine shop and could get flat tappet regrinds for like $60 shop cost.it would sure be nice to drop a $200 cam into this, but that is just not an option it seems?
