bottom end bearings

In my years of building engines and trial and error thrown at me, I have learned If you can't afford to have the motor Aline honed and rods re-sized. and bearings just the right size for racing 6500rpm and above the motor can not be put together tight. it will spin a bearing or blow up because the tolerances are to tight.well here's a little tip that can help a bunch pull the rods out look at the bearings if they look OK then more than likely the Main bearing will also. you can change the rod bolts and get a way with it, at home leave the bearing that came in the motor in the motor. the factory Clarence's will be slightly more than what they were from the factory and spin the oil pump and if it has good oil pressure then you will be in business and save a ton of machine work and more importantly your money.Now you are not going to be able to spin the motor to 6500 rpm, and occasional 6000 rpm will suffice. now at least you will know you have good rod bolts. the rod bolts are what fail most of the time. and the rod's will break in half also but most failures . all your out are the bolt them selves. It's when you start spinning the motor to the moon is when the the rods break in half. 500 to 550 horsepower is all your going to get out of the car rods the truck rods will take another 500 rpm or 6500 rpm.all you are going to be out is good rod bolts and maybe a set of rings turn the motor over . if the cylinders all look good no over heating problems then you will only need to check compression ratio and if it has 60 65 cold cranking oil pressure then your in business before you do anything check compression ratio and and if it looks good inside the motor then your out what, $150.00 for a long block now all the other money can go into your street motor or everyday driving thanks WR

know what you mean about -- if can't afford to . to get the bearing clearence for that ultra high 6500 RPM --- I just get some brake lathe cutting and mix with oil . coat the bearings with that mix . and break the engine in . then just drain the oil , filter it thru a sock( use a sock that needs washing) reinstall the oil . dready to go for 9500 RPM if you got the valve springs . springs are another story.

theres always someone who does not understand how to save money ad or scrounge for what they wot if you did not like what I wrote then simply leave it alone some people just look for a fight

Spell check and and proper word definition are a must when posting on an internet forum, even when the information is a general meaningless ramble.

Well I have read that the HP isn't what kills the rods, its the rpms. You can get the rpms up that high IF you work the OEM rods properly. By grinding down the excess cast it eliminates weak spots and in term allows them to spin higher rpms. Someone on here spun stock rods at 7200 rpm for 30 seconds in a burnout contest and nothing broke. Of course balancing is required if you do this though.

Don't be so Quick to put me down. I may not have the education you have. maybe I did not do so well in school so try to understand where Im coming from I would never tell you anything about a motor because it would be meaningless ramble. who said you had to read it or comment on it in the first place are you a rich boy with loads of money? and your daddy bought you everything and you have never worked a day in your life?? well thats what you sound like Can you here yourself fuze ball. I have worked a circle track engines and drag race engines any where from turbo charged to blown motors carburetors degreeing camshafts selecting a camshaft for a pro stock team you name it I have been there Pictures of me incarcraft and drag times and 460 fourm just to name a few FUZE BALL now lets see what you email this time I'm dieing to read it so get that keyboard warmed up Mr know it all! people say that people you know everything or think they do actually know nothing or don't have a clue to busy looking for fault on email's there fuze ball WR

I set my engine clearances to run the motor wide open and on a cold motor. if you do run a cold motor with standard clearances or God forbid just throwing the bearings in there the engine will not oil properly and blow up. and the only time you would need to run a high pressure high volume pump would be with 8000+ rpms then you need to take oil and pump it from the pressure near the oil pump to the rear of the block among other things that takes to long to write WR

Well if you can't afford a set of bearing then just maybe you shouldn't be tearing apart any engine to rebuild it then... if you can't afford it then stay the hell out of the engine....

I have found that most people that are disabled are just honestly to freakin lazy to work so they figure out a way to get disability....

some people are negative bout everything in there lives, and no one wants to be around them since no body knows anything but them. learn to see the forest through the trees.the ordeal is about us blowing up a engine and we needed another short block right then and now some one said here's a junk yard about a mile down cant remember any way had no way to take it apart and check it $10,000 was on the line so when we got it ready I filled the crank case full of synthetic oil and spun the oil pump over and it showed 65 cold cranking oil pressure we were in buisness I needed Just one pass to get me down the Quarter mile track it held together at 7200 rpm and won the race with it talking about stressing factory parts that pretty good as far as I'm concerned. I don't lie I Do not have to lie I have had a stroke and a shoulder replacement that the doctor had to sign off on in order to get a disability check every month.an by the way that money is our money Moron that you and I paid in while we were working so get your facts write before you quote what some one else tells you I heard the is and they are the doctors will not sign off on you to receive disability unless you are disabled. some people say I saw oh so and so over there working or what ever and do not have a clue what might be wrong with person so get facts before you tell people that especially someone that is disabled. I it was easy to get disability then everyone would be on it. I'm 56 years old now so I have paid my dues in the military also but what do you care you are only looking for trouble I can't wait to here from you your so kind and good to email to

I LIKE.........BIG......... BUTTS ...........

Wayne, you are bringing all of this love on yourself. There are lots of good guys here, but you can't always take stuff too literal. Spoiled brats or whiney little rich kids aren't what hang around here, just a bunch of good ole boys. Name dropping gets you no where around here, we don't care if you are freinds with some pro athlete, or a cam grinders kid. You get graded on the quality of the info you provide, or questions you ask and how you utilize the info given. I am truly sorry that you are disabled and the Lord blesses us all in diffferent ways, so lose the attitude and thank the Lord that you are able to enjoy a hobby and have fun.

Wayne I am a god fearing man and a Deacon so with that said if you are going to build something to race don't cheap out on bearing. I don't care if the copper is not showing if you going to race and you build a set of heads and change cams and put more pressure on the piston you are asking for problems.So I would say put new bearings in and one of the most things people don't change the cam bearing old cam bearings will make the oil pressure be lower .Most of us on here are not after running a junk yard motor,We just go to find a good block and start from there I say again most of us on here.So telling someone to use there old bearing I couldn't sleep at night if I heard they spun a bearing because I made a statement that it was OK to use there old bearings.I used some used stuff on my engine not saying you have to buy everything new,just bearings and oil pump/oil pump pickup.
