72 dart w/17" wheels. What problems?

3:91 gears suck big moose **** on the highway.. even with a 28" tire... a 3.23 gear is a great all around gear.. everything is gonna be a compromise somewhere along the way.. figure out exactly what you want in the end and build towards that,
Hahahahahaha. Moose c. Never heard that in a while....

I will be on th highay maybe 10% of the time if that...

I can handle the shaking and noise I think with the 3.91...

Or will th engine explode?..
