A bit hard to tell mate. The wheelbase looks about right but I have never seen a shot of Blown Hell with Cragars and this one has a 56 front clip. In addition this car appears to have spindle mount front wheels and Blown Hell has bolt ons in every photo that I could find. One more point--this car appears to have a full width main hoop roll bar as you can see what is either a diagonal or one of the rear braces while Blown Hell (as originally configured) only had a hoop behind the driver.
