Ive got 454 Big Block Chevy to 460 im going to prime it as you tube and yourself have said thank you Sir for your help .
Sound's God like 👍 on your stand fantastic 🎉
Mine would not prime the passanger side untill I put the msd distributor in then it instantly got oil on passanger side
If you rotate the motor as you prime it should help get oil all through the motor.
Yes I know I did not notice untill editing that there is no futtage of priming and bumping/sling the engine over but even rotating with a stander HEI it would not prime the passanger side I changed to the MSD with o rings after measuring the distributor hole in the block and found it to be slightly oversized from standard for some reason assuming somebody owned it for some reason not sure but got all pressure to passenger side with MSD almost immediately on fire up it was just bypassing to much oil around the distributor with the HEI and priming tool
I have a small block doing the same thing. I will check my distributor. Thanks man. Very helpful
@@jb-ik8sj you’re welcome and most cases with a small block I have not had this issue. I’ve only really had it on two big blocks where they would not push oil on the passenger side even running. I fired this engine up and ran it for a short time and it would not push oil on passenger side, who really knows these days we’re working with old engines that have been played with by everyone
That’s awesome you got oil to the top. It sounds healthy. I bet it runs hard once you get her broken in good. I also learned something! Thank you young man! Keep up the good work! I’m following.
Thank you i would have to say it sounds pritty good it was moving a little oil but not enough to make my liking with the o ringed msd it was spitting oil much happier wish I had video but realized after I did it all I did not fire it up with the valve covers off on camara
Once had an '89 Olds V6 with an oil leak at the distributer shaft. I pulled the distributor and found the O ring to be hard as a rock and square in cross section. Surprisingly, it came off the shaft without breaking. Took it to the parts store and handed it to the very young kid at the counter, told him I needed one just like it. He looked at it for a minute and said, "I'm sorry, sir, but all of the O rings we have are round." A split second later he realized his mistake, but too late to keep everybody at the counter from collapsing in laughter. A hard lesson.
Lol that’s great my Favorite parts store story I was standing talking to the manager. A guy walks in and is asking one of the counter guys for parts for a 2006 mustang. The kid looks up and says who makes mustang the manager on speaking with walks over to him and says you don’t know who makes mustang guys reply was no he walks away laughing and says you won’t make it here long will you and never told him who made mustang it was great
🤣🤣🤣 love it that’s hilarious
@@SpecialAgentJamesAki yes it was
Success, glad that you have oil to the top end now.
Your engine sounds good.
Take care, Ed.
Thank you it took me a min to find it but it’s fixed now
Bubba you need to take another look at those retainers they are definitely not the proper ones for those springs. Almost half the diameter of the spring is out side the retainer and that is not going to end well as that much stress on the outer most portion of the retainer is going to wear like hell and will more than likely end up breaking the retainer and dropping a valve.
I will take another look at that I don’t recall it being that bad when I pulled the first and last 2 springs off each head but thank you I will take another look
@@blindguysgarage yeah bud, just don’t want you having a bad ending to a nice motor over something that simple
@@johngarlick7115 I agree and appreciate it am going to take another look at it today
@@blindguysgarage as a general rule you want the retainer to cover 60% or greater of the coil diameter of the spring. Hope everything is alright with it and give it hell when you get it in something bud.
@@johngarlick7115 this is if for a buddy of mine going in. A 70 chevelle he is going to love it
Thats a good cam. It will make just over 600 hp 600 torque. Look up dz performance utbe. He built anf dyno same spec motor
@@hankclingingsmith8707 should make good power. It was built during Covid and we were not able to get all the parts we wanted. We were goals to shoot 700+ but at the time this is the only Cam I could come up with.
Lifters only get oil when at the bottom of travel. They are not pressurized when at the top of their bore.
Yes still the issue was oil would not come up the passanger side it needed the msd with o rings and now all is good
I'm having this same issue with my engine, I will research the msd orings, I have an msd but it doesn't have any orings thanks for the tip.
Your welcome hope it helps
You have to turn the engine over while priming.
I did and wile editing video i reused there was no video of that thank you for watching
I can never get my motors primed right because every drill I have used heats up, and smokes, ever have that problem??
Yes, unfortunately I have burned up a couple drills priming engines. The 1/2 chuck drill. I’ve been using has been pretty good for a few years though. This was not nice. I popped in that MSD O-ring the distributor and it had oil pressure immediately on passenger side, though kind of crazy.
Can you tell me the specs on your camshaft in the 496? Duration @50
Yes is a
lunati 40110733lk
DUR@50 249-254
Lift 663-680
LSA 110
It’s smaller than what I wanted for the build but will work great when it was bought there was nothing on the shelf for Cam manufactures and custom grinds were 8 months out
I got a small block (hydraulic flat tappet) not getting oil to some of the rockers and im at a loss!
How much oil pressure do you have and how long have you attempted to run the engine or have you just done it with a priming tool and drill
Nice big block
Thank you
what cam you runing
lunati 40110733lk not as big as we wanted but at the time of building this engine it’s all we could get
Happy Thanksgiving 🦃 !!!
Thank you happy thanksgiving to you as well hope all is well
Have to turn it while your priming
I did this and nothing it started priming once I use the MSD distributor with O-rings on the passenger side that is
What heads are those
I don’t know for sure what brand but they are a over seas bare casting that are fulley check over buy my shop in CA that builds them he thin installed all parts valve guides springs esc also he dose all cnc work on the heads 335cc ovel ports 115cc chambers 225 188 valves If I rember right I can’t give his info if you would like
Rotate the engine with a breaker bar
I did as I was priming and still nothing I did not realize until wile editing that I did not have any video of me doing so
Your spring retainers are too small.
Thank you for commenting I had somone else say this as well I have sence checked and changed them here is the video where I made this adjustment

It’s smaller than what we where wanting for it but it’s all we could get at the time with parts shortages
Thank you for watching
Alright
Alright
Please don’t waste your time on school
You can blow 15 motors n still not have spent the money on one semester
Life is my school and I lurn from all my mistakes well some of them lol
Big waist of time. You said it yourself you ran the engine for 40 seconds and shut it down. Next time run it a little longer you don't need to rev the crap out of it just let it live.
Not sure what you mean but big wast of time but I did everthing to the oil to the top passanger side and it would not go.
Ran a primer tool for more than a few minutes wile spinning the engine over by hand.
Cranked it and let it run multiple times
Then changed the dizzy and used the msd with orings and had oil to top passanger immediately
But thank you fo watching
When you are a rookie and don’t realize it. Go back to school bud!
Thank you boss you might be right or or could be that I am mostly blind I don’t know but either way thank you for the commenting and watching
Before you realise you have to rotate the crank whilst priming the system, I definitely wouldn’t be running that engine with those Spring Retainers. Just saying so you don’t destroy all your work😢
@@warricksmith2640 I did rotate engine wile priming it was bypassing to much oil at the distributor after I put the msd with o rings that fixed all my issues and I do need to remeasure the retainers just have not done it yet but I am gojng to will let y’all know what I find
Where's your video's at school boy?
@@quantaviousmooney3675 not sure what your asking
you need to rotate the engine !
