Is this too much engine or just right for a K5 restoration.

Guys I'm just starting to get in to my '72 K5 restoration. I'm gonna replace the very tired 350 with something a lot stronger. The vehicle will be a complete frame off resto and will be drivin only as a weekend cruiser but besides sounding cool, I definitely want it to be able to get up and go. It will be factory ride height with either 32 or 33 inch tires. Tranny transfer is the SM465 / NP205 combo and rear end gearing is probably going to be 3:54 (definitely not any taller as I don't like having it rev overly high at 65mph).

Motor:
402 small block (dart shp block)
I'm not going to get in to the engine specifics but a similar build dynoed at 495hp and 515 ft/lb torque.

I would really appreciate thoughts on this especially from those running higher horse engines on a similar drivetrain. Is this too much or just right.
