Your honesty is really appreciated Thank You ! I enjoy Your tips please keep up the informative updates . Best Wishes and Good Luck . 🇺🇲🇵🇷🦊👍
Wouldn't have it any other way, thanks!!
again great information
Glad you think so!
Stand up move. Much respect to you. I appreciate your videos.
Thanks I wouldn’t have it any other way. Glad you like my videos.
Great tip, thank you!
Glad it was helpful!
I really respect you owned up to something idiotic. All people come to incorrect conclusion all the time and never admit it. You're awesome - and real.
We all make mistakes and often times learn more from our mistakes so there is so much value in keeping it real and not glossing over when something doesn't go right. Thanks for the comment!!!
I will use that ladling tip. Thanks!
👍
You are a stand up guy sir.
If I couldn't do it with integrity, there wouldn't be a point.
Good job on the correction.
Thanks!
Hey Buddy, Congratulations on your first build AND your commitment to try to do everything right. Good Job!
I have built a bunch of engines and I have a couple of thoughts you might want to consider. I always use a stone on a die grinder and smooth that machine line around the edge of the blocks deck. Then I smooth and semipolish the lifter valley. I do this to reduce the chance of stress risers and to improve oil draining. Those are a couple of good reasons and if you wanted to do the tape thing, you could with your technique or the razor blades. I don't do either, though. After I install the heads, I spray both of them at the same time. This paints the areas of the deck that are exposed... I do mask the intake area and paint the long-block before I install the intake. I also just 'sit' a set of valve covers on it to NOT paint the rockers and all. That's just my way of doing things. Whatever works for you and you are happy with, is the best way to go!
I will recommend that you consider the deburring and polishing though. I look at it like this: If it doesn't cost anything but time, it's a great investment for keeping my expensive motor just a little bit safer!
Take Care and Nice Videos! -John
Thanks for the comments. Cant paint the block and heads together because the aluminum heads are not getting pained. I appreciate the info on cleaning up the edges.
Saw this on Uncle Tony's channel. Cool to see a correction to what "seemed like" a really good extra step in block prep.
It is a very popular myth because it really does look like the moisture is coming out of the block. I fell for it and would have continued to perpetuate it had my error not been pointed out to me.
Nice save on the video! Sounds like your friend is a little sketchy. 🤣
Very! He got a shout out and a link to his channel on the first video but I didn't figure he wanted to be known as the guy spreading the myth so I removed that part. 😂😂
Just pulled my 302 from my 88 mustang today, gonna be my 1st build, ive pulled plenty of engines and transmissions but never built my own, i bought a trickflow top end kit and a holley systemax new upper and lower, my plan is to send the block to machinist and have it cleaned and bored .030 over for a 331 stroker kit.
should be a fun project and a lot of what is in my stroker video series should apply. Let me know if any questions come up. I am not a master engine builder but have done a few.
Full kudos on correcting your video, and offering the correct explanation , it's the same function when bringing a cold beer out of the fridge into a warmer climate.
Hydrogen can enter between steels and cast irons, being a very small atom, look up "Hydrogen Embrittlement" or "Stress Corrosion ", another feature on oily and dirty cast materials is the contaminants coming out on heating, a cast or media blasted surface has a very large surface area for its apparent size.
Works brilliantly the file on masking tape, rat tail, or round files especially.
Like the engine stand, nicely geared for ease of rotation 👌.
Thanks for sharing.
Regards John from the UK.
The engine stand was one of those projects that once I did it I was like "why didn't I do this years ago!!"
You can lightly tap the edge with a hammer to cut the masking tape; works better than a file. I'd put the head on the block though and cut around it because heads don't always cover the entire mating surface, then you get an unpainted area that rusts.
Having done both I like the file technique better.
Cool trick with the masking. Using that little needle file is a nice delicate way to make it perfect.
Glad you like it!
I start laughing when you first started this video using a propane torch. Glad you learned it was the concentrated heat using a flame that caused the metal sweat. Neat idea on using a pencil file to mark the masking tape for a clean sharp paint edge. Thats a interesting engine stand you have there. You need to do a video on your engine stand.
I have been using the file technique for 20 years and much prefer it over the razor blade. Takes a little practice but the good news is tape is easy to replace. As to the engine stand I do have a video on it. It was one of my first videos so it is not very good. It is also description over photos because I wasn't making videos yet when I did the rotating engine stand. ruclips.net/video/C7qOrofD4Hs/видео.html
Nice tips! One thing I always do to my blocks before painting is apply Picklex20 as a metal conditioner and prime with epoxy primer.
I have never used the Picklex 20. I will look into it. Is the epoxy primer high temp, or just standard?
@@dazecars Just "regular" EP.
👍
Any more updates on the 393 Windsor build??
Still on hold. I finally picked a cam. Next video will be on cam selection and then I will get it put together. To many projects and only one of me 😁
@@dazecars LOL. I get the to many projects and only one of me. Looking forward to your next video
I will likely put up the next video in the 393 build in the next 2 or 3 weeks
But you're putting small filings in the block..!
Best to use a hard poly or rubber mallet. NO METAL SHAVINGS!
Not really. When done correctly there aren’t any metal shavings, and nothing a little compressed air could not fix. It would be different if other parts of the engine were already installed.
@@dazecars Tap the block edge lightly with a hammer to cut the tape. That cuts better than a file.
@@Spiritof_76 Having done both I like the file technique better.
