That is a big cam, plus you have an auto with 2.76 gears . Not good for driving fun. If you had a nice restoration take advantage of the long strokes torque boost with a reasonable cam. A cam with duration and lift like that is going to sound like a demented popcorn maker. Weird but that sometimes people like that. They make for poor overall performance, from a drivers perspective, to me at least. If you had .450-.470 lift it would make a sexy bubble. You made what made. Now spend a day swapping the ring and pinion to 4.10 and pay the piper.
If you built it for that cam, you should have gone high stall, big gears. Hot rod did this build?
Nothing to be scared of using a 262. Dynamically it is a better choice.
Finish the combination you made and enjoy it. It will be highwayable with 4.10s , just busy.
