@GreggeSB Год назад

Isaak Welch there are some folks who have the misguided belief that a sleeved block will never be "good" again. Like with the Jaguar block they recently repaired, I believe a sleeved block is just as strong, or maybe stronger than original. If a Steve Morris SMX engine will survive drag and drive events being designed as a sleeved block and make 4,000+hp, this motor will survive another 56 years with it's new cylinders.

@otterconnor942 Год назад

At my work we have 1.55 inch diameter bore seals that have an interface fit with the bores they're in. We don't heat the bore, and we only cool the seals in liquid nitrogen, and they fall in with no extra pressure. The much larger cylinder sleeves will shrink more than the much smaller seals that I deal with, so you should have more wiggle room and no need to heat the block, and not risk galling the bore or sleeves

To answer the question posed by the associated short for this video, yes this block is worth saving. Whenever the reason for saving an engine part is to keep the car numbers-matching and the car is classic enough, it is always worth saving that part. Not only that, if someone is willing to pay to have it saved, there's no reason to not save it.

@markmurray7031 Год назад

I've put lots of sleeves in and I put a lot more press in than you do.The old machinest rule " .001 for every inch " Another thing I don't do is all sleeves at the same time. I do one and skip it's neighbor. Reason being, once you press one in it will distort it's neighbor and that could lead to all sorts of problems down the line. I also use green Loctite on the sleeves and block. Heating the block is essential as you want the block to relax against it's new sleeves. I worked for R&D mechanical engineer from Pitt University who had many years of race engine building under his belt and I learned a lot from him.

@andrewclarkehomeimprovement Год назад

Really well done. Question. Where you cut the valve reliefs, I think I saw that it cut all the way through the wall of the sleeve into the native block. Will there be a potential blow by/compression issue down the side of the sleeve?

@dondonald69 Год назад

I was thinking the same thing. Thanks for the great content. 👍

@Pooslingingmonkey 11 месяцев назад

Honestly that confused me. Why would that need to be done in the first place? Only thing that comes to mind is both intake and exhaust valves have been made bigger cramping up the combustion chamber so they cut that in the piston bore for when the intake valve opens. 🤔

@Turboy65 Год назад

For future reference, if you were to indicate the valve clearance cutout arc at three points, you can mathematically determine the diameter of that circular arc and also derive the center position of it. There's no guesswork. It's measuring three points and doing the math.

@johnmar7701 Год назад

I thought the old 396 cid style blocks had 0.030 inch extra meat on the bores. So one year the engines were advertised as “396” cid motors when they were actually “402” cid from the GM factory. Per Zora Arkus Duntov, “Cast iron is very heavy so we took another 0.030 inch overbore to lighten the engine”… something to that effect.

@bobbrinkerhoff3592 Год назад

From '65 to '69 the blocks were 4.094 bore diameter , in '70 they opened them up to a 4.125 bore ( 402 ) cubic inches . Excuse me I should have said for the 1970 model year , as I have a block dated Nov. Of '69 that is a stock bore 402 .

@skylinefever Год назад

It was my understanding that smog laws for engines over 400 cubic inches was different for smog laws for engines under 400 cubic inches. For legal convenience, GM gave the engine 402 cubic inches.

@bobbrinkerhoff3592 Год назад

@@skylinefever the smog laws were the same across the board, main thing was Chevrolet had the 400 small block coming out for 1970 , and couldn't have a big block that was smaller than a small block . GM wouldn't let them spend the money to make tooling to cast 402 emblems . If you ever see a '61 Chevy it shares the hood lettering with the '60 Chevy , " cause you spent too damn much money on that tooling " . Also , it gave Chevrolet bragging rights as having two engines over the old 400 inch limit in their intermediate car ( the Chevelle ) , the other divisions only had one .

@georgiafan6618 Год назад

I assumed you would have to deck the block after sleeves installed before you’d cut the valve reliefs. Wouldn’t this better establish where valves would end up near block surface? I didn’t realize this amount of prep was involved in an engine build. It gave me a perspective on labor and good machining practices that I’d hope all shops engage in. 👍

@southronjr1570 Год назад

Curios about something, why did you cut the valve reliefs in before you decked the block? When you deck the block you will essentially be making the valve reliefs more shallow and depending on how much you have to take off the deck, couldn't that cause the valves to make contact? Did you cut them deeper than needed with a guesstimate as to how much you will be taking off to clean the block up or is there already enough clearance in the reliefs to account for the decking?

@cheerdiver Год назад

Excessive labor. Decking would have moved an already established 'zero point', due to being removed from the boring bar fixture.

Being a Job Shop Journeyman Machinist prior to getting my Engineering degree we would always put sleeves in the freezer overnight or in a vat of liquid nitrogen, once the nitrogen stops boiling its as cold as its going to get. Wear heavy welding gloves when handling sleeves out of the nitrogen or you will burn yourself. You could literally drop the sleeves into the block. Thank you for sharing, I do miss machining.

The few times I have sleeved all cylinders in a block, I did one at a time. Bored the block, install the sleeve, then set up to bore the next cylinder. And so on. Take so much from all the cylinders really compromises the integrity of the block. Doing them one at a time minimizes how much the main webs, deck, and cam tunnel move when you sleeve all cylinders. People think metal doesn't move, but it does.

I dont know if this is true or not, but back in the day I remember reading that the sharp edges left in they cylinder by those valve reliefs need to be softened / rounded a bit where the cylinder wall meets the relief so they dont create a "hot spot" and contribute to preignition / spark knock.
