To remove the head stud from the head, double nut the block side and then "thread" is down through the compressed aluminum at the top of the head. Some all aluminum LS blocks have had the cam bearing walk issue. They do pin those cam bearings in place. It's usually on blocks that are similar to Randy's. Dry block/heads that have had a lot of heat cycles and high spring pressure and rpms causing the shrink fit of the cam bearing to loosen slightly, usually by only .0005" or so. You could be getting the valve to piston contact due to the cam profile and spring pressure. Due to valve train mass, the lifters don't follow the closing ramp on the cam and hop over it. That can cause the valves to remain open longer and contact the piston at higher rpm, even though there's plenty of clearance on a standard valve/piston clearance check.

Will last about 50 passes on 2000 + hp engines I got around 250 passes at a lower power level on the street. No load on the engine when street racing. Line 2 Line is a bandaid. Sleeve the block and buy new pistons or continue to have issues

One side of rods typically are cleared for camshaft ans sometimes bolt stick through a little only on 1 side of rod

@andrewshuford Месяц назад

MGP says allow .010 for a 6" alum. rod to lengthen when at race temp. They also say to allow around .020 for rod stretch when the piston comes to a stop at the top and to allow around .025 for piston rock.

@scottsherrard Месяц назад

Sand the stock thrust face down until the crank hits the roller bearing a few thousandths before it hits the stock bearing. Use some emery cloth on a flat surface.

I was there this day to see what John does as far as recording and the making of these videos as well as working on the cars. After seeing this video wow is all I can say on the editing! Randy and John great people just hanging out and helping as little as I did what you learn simply listening to John worth every minute! Keep up the great videos minus the big problems! Just tell Randy the scramble button and 52 psi we ain’t there yet lol

@Flitzer514 Месяц назад

Use that Line-to-Line coating on the pistons so you don’t have to replace them.

@jamiemuncy2219 Месяц назад

Idk how tight your piston to valve clearance is to start with but you know those aluminum rods grow some and with piston rock, ide say that's why your tipping the valve. Those Shelby blocks are a thing of BEAUTY, BAD ASS PIECE💯💯

@baby-sharkgto4902 Месяц назад

Could you go with a little longer bushing to hold the bearing in place?

@Smokey72013 Месяц назад

Pull that pipe plug out next to that stud and I bet you that stud will come out a lot easier. Also on the thrust you want to see kinda a shared load. On engines I've messed with I clearance the bearing or shim the roller bearing so that when you push the crank forward I have roughly .002-.005 clearance no touching on the rear standard thrust. That seems to share the load well between them both I wouldn't think of removing the rear completely that would make a jump rope

@dannylee9138 Месяц назад

Making more power than the block can hold the crank stable in the mid 80s I helped with a top fuel team and I saw that exact same thing too much block flex. The engine builder made a main bearing plate that mounted on the main caps and that stopped it.

@raymondguzman1907 Месяц назад

I'd take it anyway but I would check the crank with a micrometer to see if that main journal area has any runout before taking it to the machine shop just for the hell of it.... and as far as the valve kissin the valve relief i bet your on track about the piston rock causing it as much scuff the skirt has on it. From what i can see in the video anyway, It makes sense to me.... That's alot of high dollar parts there. Can't wait to see/hear that bad boy fire up

@yarrdayarrdayarrda Месяц назад

13:13 the valve contact shows me the pocket location is a solid 0.100" insufficient and way overkill in depth. I'm not sure if thinning out that piston lid is going to create localized burning/cracking, the engineer should be able to advise you. Might be worth getting a hard anodizing/heat protective coating, it's certainly worth sending the pistons so they can make the required corrections for those intake valve pockets.

@whereisamerica7384 Месяц назад

I been thinking about the VTP clearance issue. I wonder if the valves hit when the car spun the tires, piston rock or is the cam lobe profile so aggressive it is hopping the lifters off the cam at high rpm. It was probably just a perfect storm. Combination of all of them. When you start making that kind of power with a sbf who knows what is going to happen. It's super impressive btw.

@leesanders8824 Месяц назад

Way outside of my wheelhouse here because I've never messed with anything close to this stuff but Brand racing engines drills and set screws the cam bearings in LS motors to keep them from spinning. Just a thought.

@paulgriffin6723 Месяц назад

What about the coating steve morris puts on piston to stop the rocking

@Alan-kb4oq Месяц назад

Why not get TKM to put the motor back together, plus they can also tune it for Randy and hopefully it should last longer to race then keep taking it apart every week after every event.

@user-hw1cw8vm9t Месяц назад

@jkfonyi Месяц назад

Lot of big name engine builders prioritize the roller thrust over the internal . In my opinion it makes no sense to put a roller thrust in and not really use it .

@jasonstormoen Месяц назад

That high hp draglife. I imagine you did, but did you double-check piston to valve clearance to make sure it's what it's supposed to be? Keep up the killer work. Curtis and Dan RFD are awesome. I've been dealing with Curtis for years, and Dan for a good while now too..

@yarrdayarrdayarrda Месяц назад

V-P contact in this situation is absolutely insufficient radial clearance. You NEED 0.060" radial clearance, valves machining their own reliefs are destined to drop. FWIW you can dingle ball hone a cylinder for a long time an not remove more than a tenth or so of cylinder wall.

@donaldmoore7418 Месяц назад

How much camshaft thrust do you have? I have a similar setup and the previous builder used the wrong Jesel zero thrust camshaft adjuster on it. Mine had .045 when it should have .003-.009

@MrMertstube Месяц назад

Look at Line2Line coatings for the pistons.

@VRMN8R Месяц назад

Id guess that the spud "spun" a little on the shaft of the cam gear when the valve touched the top of the piston? The cam gear kept turning when the cam stopped for that split second??? Just a guess.

@johngoodman7160 Месяц назад

Roller bearing the cam stoped all my problem 😊

@davidresar8256 Месяц назад

Line to line coating on the pistons if the cylinders don't have taper. That valve relief is in the wrong location. The valve should have more radial clearance. Are you sure the cam roller bearing didn't get installed at the wrong depth?

@bigswingin6316 Месяц назад

The way that valve is hitting the piston it looks like the pocket on the piston needs to move, Looks like it doesn't match the valve angle at all

Big block Chevy had the same problem with the valve relief too close to the edge of the piston so in boosted applications we would actually go a little bit smaller on the intake valve so that we can have more meat in the edge of the piston As far as the camshaft bearings go the block can be modified drilled and tapped for set screws to keep the bearings in place fwiw

You Definitely didn't have enough radial clearance on your inlet valve pocket... You know the way,your an engine builder.. pistons all in, heads on with no valves, TDC.then use a center dot pilot to mark center of valve diameter.. then you can measure your clearances... Did you give head type and valve sizes to piston supplier.. ??
