Paul,
If you are still online the sharkmouth will be about 25 sq inches directly below
the spinner.......The spinner is 16 inches diameter and about 24 inches long and
more tapered (not so blunt).......The starter is on the sparkplug side of the engine
(88 auto transmission bellhousing)........Do not worry about the radiator (coolent)
openings as they will be located at the firewall with the openings below the airfoil
leading edge (the complete A/C is an airfoil) ..........Use your own judgement on the
shape of the sharkmouth .
Thanks
Kelly Troyer
I don't think the shark mouth is going to work with the Russell.
I suggest a more conventional or traditional cowl.
