Gear Vendors in a '67 Barracuda, is tunnel clearancing required?

Nice! The Gear Vendor has been the best upgrade so far on my 68.


I have a 67’ cuda, have a 408 stroker and 727 coming from blueprint engines. Was thinking 323 gears (Dana 60), and hoping the near 500hp would help on the low end and 323 would be good for 75-80mpg hw driving.

Would I see a dramatic increase using a GEar vendor set up?

what’s your set up and still really happy with everything?
