What is the fastest and most secure way to fasten a 2x4 to a block wall?
Answers:
Frame a wall with header, footer, and 2x4 on 16" centers. Just like you would any other wall. Secure at top and bottom.

Good Luck!

Use concrete anchors and bolt on.
Use concrete anchors and bolt on.
You can use 1x2 for this. It will save you a little money & be just as sturdy.
I used anchorman's. I drilled a hole, set them in the wall & bolted the strips on. You will have to recess the bolt & washer so your drywall will lay flat.
I frame walls in front of the foundation walls securing the top to the joists and the bottom with a powder actuated nailer (you can rent it) or fluted masonry nails. This way, you know the walls are plumb and you're not relying on the job the masons did. It also gives you room for insulation and electrical. If you are still plan on putting furring strips directly against the block, use construction adhesive and fluted masonry nails (don't go overboard with the nails, too many will crack the blocks) and try to nail in the mortar joints. The nails are there primarily to hold the furring strips in place until the construction adhesive sets up.
Don't use a powder actuated nailer on the block, it can blow right through and cause a big mess.
I agree with not using a power nailer, but you might try TAP CON screws.
Predrill the studs, marking the block, move the stud and use a contrete bit in the appropriate size for the TAP CON, usually one bit is included in a package, I suggest more.
As long as you don't "Wallow" out the hole as you drill and use the proper driver for the TAP CON you should find it to be as secure as many other ways of doing it.
Also block should be easier to drill into, as opposed to long set concrete.
Certainly there are other methods, such as anchors, and they can be as effective, especially any that expand when the screw is installed.
After, add insulation, wiring if desired, and drywall.
