What is the ET limit on a bolt-in roll bar? Watson and others have really nice kits that bolt in for these cars.

i think the rulebook says a roll bar has to be welded to the floor. i could be wrong

Part of the reason I put a 6 point in my Q/SA 4 cyl Stocker

Or welded to 6" x 6" plates attached with (4) 3/8" bolts.
The floorpan is sandwiched in between the plates

First I have heard of that.
There are some in the 9's now but I have never heard of an aftermarket block for the 2.3 EB.

Low 11's stock longblock:

Watson makes a chrome-moly 6-point bolt-in roll bar, but it's 1-5/8" tubing, so it wouldn't be NHRA legal, and it has a road-race type diagonal within the main hoop, which is unnecessary for this purpose.

Is there a particular reason it has to be chrome moly and not mild steel ?

It doesn't HAVE to be, but this thing would be a little bit of a porker, so saving an extra 20 pounds of steel seems like a good thing to do.

Wow.

This 2015 Ecoboost Mustang with an automatic ran UNDER the K/SA index, hundreds of pounds overweight and stone stock right down to the tires, except for an aftermarket "tune" that picked up 64 horsepower:
