TC76's would work great with a .81 back side.

quicker spool and back pressure will still be low.

I mean I have a .81 on my rear mount stock cubes.

Back pressure is bad, but that should not be an issue here.

What are your power goals and how do plan on using this ie street, strip?
How high do you want to revv it?
More specs on it.

Not a dumb idea, but you're not asking any specific questions. No guarantee you'll get the answer you're looking for but you've got to ask something for someone to answer.
