Anyone know what this engine is from?

I am looking at another supposed 69 vette 427 engine and here are the numbers, can anyone add anything to this? The deck numbers seem off.

BTW- The "other" block turned out to be cast, not aluminum!

427
Block Casting 3935439
deck TO5282BY (maybe a H after, or a smudge)
Hi Perf Truck/Pass on the back
and CONV2 longways cast into the rear by the GM, what does that mean?

Heads
rh: 3873858 f226 hi perf
lh: 3873858 f176 hi perf

any thoghts and or comments would be helpful.
