was this Hot Wheels inspired by a real hot rod ?

i know some Hot Wheels cars are patterned after real cars , is this the case here ??? 12 exhaust pipes where the intake would normally be, and 6 carbs on the side . Jag engine ? Maserati ?
I have seen the chevy V8 rod with the exhaust and intake reversed but it doesnt look like this.
the door says The Pipers, South Bay

 

Yes it was because there's some kind of engine that the exhaust came out the top of the block. Dynaflash_8 knows witch one

 

Cadillac flathead

 

look on the back of the blister package . It tells you all about it & if hot wheels designed it or not.

 

there were a few engines modified to run reverse flow thru the heads. with SBC having the center exhaust valves next to each other ,you had hot spots and cracks.

 

Flat Caddy didn't have the carbs on the side though.
