Thanks all. I've already decided I'm certainly fixing it myself. It's just a matter of going thru probate unscathed. Shouldn't be an issue- everyone in the family is in agreement.

Not far either. I’m open to help also, maybe a Saturday engine pulling party!!

I’m also in Michigan and could help out if needed!

I’m sorry for your loss. Even if the engine lost a cam lobe, it will be a labor of love and you will make it right. Enjoy every minute of it.

Echoing the sentiment of sorrow for the loss of your Grandpa, for you and the entire family. 70 was way too young. :frown:
My dad passed 10 years ago, almost to this day, from lung cancer too.

My condolences on the loss of your grandfather.Good luck moving forward.

Sorry for your loss. We are here to help!

Sorry for your loss, hope you can get the car roadworthy for him.

Lost my dad in 2020 from COPD (smoking) and some other health stuff and Covid finished him off.

Alright fellas, I still haven't learned to leave well enough alone.

I monkey'd with the one noisy rocker today, and actually went in the right direction. Then it started doing this. The pushrod is straight, the lifter is working (put my finger on the pushrod and ran it) and whether the rocker is on, off, loose, properly tightened, doesn't matter, doesn't care where the distributor is, it does this. I leaned both carb screws half turn each, I don't think it's actually backfiring. It still makes 55psi cranking and all the other passenger rockers are fine (I didn't feel like fighting the driver's side around the booster to be honest)

Ideas?

(This is where I really wish Pappaw was still here. He could probably listen to it for half of a second and tell me exactly what's wrong with it)

Sounds like a cam lobe going flat, usually the exhaust letting the burned fuel back fire thru the carb. Pull the left cover and instigate.
