Keep it simple especially for a street build. You want to drive the car not work on it all the time.

As for a block being a month away I just laugh. My builder and me heard for almost 18 months that a block was a month away. Don't believe Tim. If I could have gotten a Indy or BM block during that time I would have. Thankfully my engine is almost done. Damn covid and lack of parts sure slowed down the build.
