340 six pack hood closing clearance?

i would have to cut air cleaner? I can very easily just get single speed wiper motor if that makes a difference

FWIW, mines a 440, but a shaker base plate only needed a slight bend to "accommodate".

As far as the hood brace in my '69, there's just a hint of love.....

Rather than cut hood bracing, one could fab 1/4" spacers to lower the K-frame and gain a bit of clearance.
