I've got one on my 69 big block with the correct GM frame pads and a 14X3" drop base K&N filter set-up and it barely clears. But I'm running EFI and the throttle body is about an inch shorter than a carb so you would have to run an even shorter filter. Throw in a nitrous plate and I think you'll have problems getting a filter on there.
