why has my"Q" code car got odd front shock towers

I have a 1969 Cougar ‘Q’ code 428 car with
odd front shock towers, [not normal BB towers]
that almost seem factory made
to fit a 429 in the car
I would submit a photo but I’m new to this forum and do not know how
my e mail is barrymilesss@gmail.com

Could you post pictures? I read ones some place that this could be done by drag race car builders who wanted easier access for working on the engine between races.
