In the process of restoring our 72 challenger, we're on the point of choosing rear axle components.

We did not run our 493 engine yet, but we need an estimate on the max rpm.
All new parts, specs:
493 cui, 10.88 compression ratio
edelbrock performer heads, 88 cc
edelbrock performer rpm intake
Speed demon 850
Comp cams XE275
2" tti headers

There must be someone already running this combo!!! Thanks!
