which would you do?

I currently have a ford 8.8 limited slip rear with 3.73 gearing. it is stock with drum brakes.

I can get a 69 camaro rear with aftermarket axles, posi or limited slip... and 4.56 gears for next to nothing.

Here is what my concern is...

Rear End Ratio: 4.56
@ Desired MPH: 65
Tire Diameter (Height) in Inches: 27
Over Drive Ratio (1 for no OD): .7
RPM at Given MPH: 2582

Rear End Ratio: 4.56
@ Desired MPH: 75
Tire Diameter (Height) in Inches: 27
Over Drive Ratio (1 for no OD): .7
RPM at Given MPH: 2979

It is still under 3k so it seems like it should be ok. right?

normally the truck will be an around town cruiser but I will be driving it to the coast and vegas some too.

EDIT...part of the appeal of the camaro rear is that it is the same bolt pattern as the front.
