+1 for 6spds in foxbodies...
that's what they're good at doing...keeping the RPMS low on your 3.73 or 4.10 gear so you can Cruise on the HWY and keep engine temps down and MPG up

I'd love to have a 6 spd...I drove an R32 VW tonight and it has a 6spd..I felt like I was in 4th gear cruising @ 40mph just b/c of normal driving & keepin the revs down...
