Whiplash cam in Canada?

I don't know...that's why I'm asking. Dave recommends his “performance” lifters, but, of course, they’re out of stock. We got the payment issue worked out. He must be pretty busy these days as it takes days, sometimes a week, for him to answer an email.

So, who's actually run one of these in their 360? Would like some real-world feedback.
His roller lifters work well if you can get them , i'm using them now on my 426 stroker over 9,000 miles and no problems yet , my new build i'm using solid FT lifters not a roller cam as getting new lifters is getting hard Dave told me a few months back that they should have lifters by november
