New engines are made to tighter tolerances than engines back in the day. You can also run synthetic oils in them from the get-go, which for a classic engine is a no-no.

Like I said, just get the 350/260, break it in as per instructions, and switch to a full-synth oil with a zinc additive at 3000 miles. It will last you 150,000 miles if not abused.

And for $1460 delivered, that's a lot of value.
