Yea if between ss sye and s on spring perch using the btf 7 inch long perches I picked up. I should be looking at around 19ish which should work. When I mocked up the motor and trans I ahd it as fra forward as I could go. So moving further up isnt really an option
you could also look into a pusher e-fan, that way you'll get an extra inch if not 2.
