I want

Thats why impregnation is important for castings especially a machined ones

Which Crower cam?

Bet a guy can do this on a belt sander eh?

I worked in a shop with one like this. I now personally own a Delta Custom Tools pressure tester.

an excellent tutorial, kept my interests and attention the whole way through

Hi, Are you still involved in the turbo Buicks? I see this video is older and was wondering if I could reach out?

The "cool guy" sitting in the back is a waste of space in one way I guess you can say he's paying so it's his loss but that's not what teaching is about, it's about interaction, questions, etc. Too bad some other kid who can't afford to be there, but would be hungry to learn couldn't take that clowns place.

When pulling the cap down to torque, do it evenly, not one side down and then the other side down, possible distortion, just saying

LOL that poor girl leaning against the wall looks like she is saying to herself “kill me now”!

👌❤️

Dave rebuilt my 109 long block for me, he pays so much attention to detail. From the machine work down to every fastener he is responsible for on the rebuild and then some. Since I didn't have the facilities to install rebuilt motor, trans and exhaust, Dave took care of the installation as well. Fixing two potentially dangerous issues he found not related to the install, as well as probably 20 others that would've needed attention sooner or later.

Awesome video Dave.

Excelente gracias

Side clearance doesn't affect oil pressure. See the link below. Other that that, great vid sir.

dummy didn't spin it while it was coming out so now it will have one side that is .001-.002 out further on the end. Attention to detail is everything if you are building a high-performance engine.

Anybody else get dizzy watching this? Someone get him a tripod, quick!

That's a Very good example of why pressure testing is important.

I love the white finish on these machines. My cv616 is green, not my prefered color lol.

What is the name of this machine? Plz reply

What is all needed to switch over plug and play, as a package, who to order it from

Thanks for posting this video. My Buick 350 has ran a 12.09 in my ‘70 Skylark last season. It has aluminum heads this year, so I’m hoping to be in the 11’s. I also went to an external wet sump oil system.

Turbo Nasty here. Nice vid

I love asking stupid questions so here goes, rather than flipping the block why not design the machine to come from both ends?? Rather than turning a heavy block around?

I was confused until the guy asked the question about loosening the cap on the bore that was already to size. I was scratching my head wondering whats the point on measuring all the bores independently as the two outer bores dictate how long one keeps boring then he asked the question about loosening the cap on each more that has reached its target, simply brilliant question at the right time as I was just about to leave the video.

No comment

Nice teaching skills, thanks a lot

Good Question! I released the pressure on the stones before I took the mandrel out of the block. There is a small lever on the mandrel that releases pressure. I also place the abrasives at 12 O'clock when I remove the mandrel, so only the metal shoes actually touch the bore during removal. Another teaching moment!!! :)

Um,, why didnt he twist the hone while he was pulling it out? didnt he make a flat spot by dragging the hone out in one place? (he did comment on how much the hone took out with very few passes, so this is definitely a thing)

How do you hook up the two step

Ok so the honing bar is not externally located? It's just located by the workpiece, am I correct?

Absolutely no one in my area does this.

I need to do this to my Pontiac 455 2 bolt main, cast num 485428. it been pre tapped for 4 bolt main. Any know the cost to do this?

Im curious what temp did you heat the rods to.

cam specs please?

this guy is a GOOD teacher. Patient, concise, and obviously knows his subject well.

What does this do?

The camera you are filming with could use a line bore. Other than that, good vid.

What's the name of the machine he uses to test the cylinder head?

very good ... but ... in end is gonna black

Personally I don't believe in messing with the main bores unless swapping caps !!!!! IV had it done 2x and they weren't worth a damn after !!!! If they are slightly off it doesn't matter do to the fact that alot if engines under full throttle and load flex up to .015 from corner to corner the oil film is strong enough to not let the crank contact the bearings and a good crank flexes without breaking wich is why forged cranks have more issues with cracking than cast iron or steel . Read David wizards books he knows .

done quite a few, I would however watch the stones at either end of the block, you will notice he comes last the rear main and front main with stones keep in the middle. stones should be even across all bores while honing.

Hi, I was wondering who made these caps and if they could be run with a girdle or not. Thanks.

your stoking way too you can feel what the hone is doing by goin faster

I was taught to never pull the mandrel straight out but to rotate it as its being removed to avoid grooves and to never stop the the motion at the end stops with the mandrel driver turning but to hit the end stop as the mandrel driver winds down to a stop

As I read below in another comment... You are meticulous with your explanations. Im paying to have this step done to an engine I'm building and wanted to understand the process and you have described it in such a way as almost any mechanic would understand. I see a couple of those kids could care less to really see what your doing. I would be all around you watching every detail. and questioning what I didn't understand. Well done.... your a very good teacher !

What process did you go thru to align the hone mandrel to the main caps?

If that was a new dart block I would've made you re do it to much inconsistency
