Right now on my '51, I'm leaning towards dropping in a tame V-8 under the hood to replace the 216. I'm hoping to have this as a daily driver and the reliability of a crate engine is more important to me right now than keeping it numbers matching. I'm not going to toss the 216, I'll got space to store it so maybe one day I'll have the 216 machined back to "like new" and swap engines. I'm lazy in the fact that I don't want to spend 30 minutes prepping my truck to drive it 12 miles to Lowes or Home Depot.
