I decided to have mine done and to be safe, made a plate to cover the VIN. The block turned out great and no damage anywhere. Based on what I saw of the block it likely would not have harmed the stamping or broach marks but decided to leave it virgin instead.

My engine builder has a shot peen cabinet and a tumbler. On all of his higher end engine builds, they are hot washed, shot peen'd and then tumbled clean. I must say that the blocks turn out great. I was so impressed I asked him if he could do my 610 intake for my 68 and ho obliged.
It turned out great as well. I'll see if I can find a picture of my block when it was cleaned. Here's the intake before I added the correct M intake bolts.

Yes there's specific media and pressure, but it is NOT rocket science, its just hitting the surface with shot and making sure you get 100% coverage,, nothing really scientific at all,, we shot peen transport catagory aircraft parts all the time,,,its just selecting the right size shot and hitting it with the flapper wheel at a certain speed and verifying you get coverage lets not overthink this,,thats what engineers do Last edited by Niblet; 01-31-2019 at 08:18 PM. |

The biggest problem I have found with the process seems to be time in the machine
It will cause problems with the broach and stamps but moreover that too moch of a good thing will alter lifter bores and put shot in every hole that is hard and time consuming to remove . I worked in aachine shop and we used hot tank We had a. Freinf who used.ampro and I did not like the extra work it caused. Since it has been baked I would finish with a wire brush Nothing worse than building your engine and then to find out the lifter. Bores areessed up Good luck |

I would buy many gallons of the evaporust and find a plactic bin just big enough for the block. Line the bin with heavy plastic sheeting to reduce the amount of volume you need to fill with the fluid. Find a outdoor pool heater and put that in to get it up to around 85 degrees. Let it soak.
Remember the rusted 455 crankshaft I found for the Gramma car engine build? https://www.yenko.net/forum/showthre...aporust&page=7 |

For future rust issues... I've used the higher percentage acidity vinegar on quite a few things and it does better than Evaporust in my opinion. This gas tank was completely crusty and full of rust scale. It was a serious candidate for a new tank, but someone suggested the vinegar trick. I filled it, let it sit for a few days while giving it a good shake now and then. I did that three more times and this is how it came out. Not a spec of rust left. I've done it on several of my 69 parts and the results were just as amazing.
