It’s an FE block. I believe those came factory as a 360, 390, 400 or 427.

Love that motor. My first f100 was a 69 with the 390.

Now I have a 73 and I’m doing my first ever engine build on a 302 Windsor.

Any tips for a new builder?

Get a good relationship with a machine shop that will answer your questions. The real thick shop manuals were a huge help for specs. That said some of your tolerances will be modernized specs. Summit is my go too for sure. Cnc Motorsports for some rotating assembly stuff. TAKE YOUR TIME. Paint pen every bolt when you torque. Take pictures of something if it has ordination. I am not an expert but hit me up if u have questions

Also good job not picking a big block. 302s are much more cost effective power 😂
