They are probably 32".....................mine are 31"...................but without a large tub you might have a little trouble fitting them in...............they did a real nice job on the body work. Would have been great to see a picture of the engine bay.............IMHO
I imagine there was extensive engine bay work to get a boss 429 in there.With a lot of power from that mtr. it would take balls to drive it.You could build those mtrs. to over 800ci in shotgun form like the old pro stocks.Since the NHRA cut the cube limit to 500ci,Ford is no longer competitive in pro stock,it is a real shame.
The NHRA always had a 500 cubic inch limit when the went to the big block engines in the early 80's, Glidden ran the Boss9 in 500 ci configuration for years, but said the hemi head was a problem getting compression, when ford pulled the plug on sponsorship, the glidden development went by the wayside, and they have never caught up.
