Sbc oil pumps?

[CNC BLOCKS]

The oil would not be bypassed if you open up the connecting rod side clearance like I mentioned earlier. If you call melling and tell them what you are doing with your engine they will recommend the pump you need if you call them talk to Renee not George I am betting if ur goin to run over 6500 they will want you to run HV in a circle track app. Also if you are running an HV pump and the bypass is set at 70 psi like the M55HV is and you are only running 65 psi you are not bypassing much oil which is a perfect condition

WTF. Bearing clearance regulates the oil that flows between the rods not side clearance.

I have built some piston guided rod engines that have .110 side clearance and have used a M55A pump and no issues.

I have built some Honda rod 283 main circle track engines and HV pump would not work on those engines and they turn 7500 with zero problem's!!!

I have never needed HV pumps with my builds but I guess you have to know what your doing !!!!

To a certain extent rod side clearance does regulate oil flow if you don't think so put an engine together with .005 side clearance and let me know how that works cause it won't!!! Clearance does regulate the flow but it goes hand in hand with side clearance. I know for a fact on a 351w ford if you go from .015 side clearance to .030 you will lose 40 degrees oil temp because the oil can flow better without changing the bearing clearance. I have built 302 fords that run better than 8000 with this theory plus out of all of the engines to come through my shop not one single bearing has been damaged or spun!! I sir do know what I am doing regardless what you believe there is more than one way to build an engine that's what makes good races!!

What idiot would ever put together a racing engine with .005 side clearance !!!!! I didn't see an difference in oil temp with a .110 side clearance.

I am not a believer in what your trying to push!!

If you wouldn't build a race engine with .005 side clearance than it must play a role in oil flow huh? Wouldn't let enough oil out through the rods now would it? So it does make a difference this is just an extreme. Volume plays more of a role than pressure since pressure is resistance to flow rather than how much flow you have I have run small block ford engines with only 50 psi a high volume pump and 10w30 oil and melling told me I had the perfect condition lots of volume without any oil bypassing pump was turned all the way up I never had a failure with the either it takes volume to cool the bearings not so much as pressure. You could build an engine with tight clearances and high pressure do to the lack of clearance but it wouldn't have enough oil flow to cool the bearings and journals

Well I see a lot of 602 circle track crate engines and I have seen some with a s little as .010 side clearance engines ran fine oil temps around 220 with no cooler and during a rebuild I open the side clearance up to at least .018 and so far oil temps don't seem to run cooler!!!

I have been building circle track engines for many years now and have seen side clearance from .015 to .045 and no big difference in oil temps.

Bill Hendrens always said the same thing I have said its the bearing clearance that regulates the flow of oil between the rods not side clearance. So far performance rods for GM builds are .940 and will give you appox .016 side clearance..

i think im gonna run stock car drivers new setup

You build them your way and I will build them mine I have also been building race engines for awhile and have the best reputation in my area for reliability in building Chevys Fords and Chryslers. We will just have to agree to disagree!!

Are you a true engine builder where you do your own machine work or just an assembler??

Scroll down my Face Book page just comparing apples to apples here to see if we are on the same page or not.

I like the 10552 pump with Brad Penn 10-30 in my builds and that's how it's run on the dyno. Most of my customers aren't comfortable with the 10-30 and when they change it they use 20-50. It's hard to break old habits.

[CNC BLOCKS]

I am a true engine builder in Nebraska. We work on everything from diesels to old tractors even back to model a and t engines plus race and high performance street engines. We don't have the CNC equipment as people out here don't want to drop that kind of cash but that doesn't mean we can't do good machine work and build good runnin engines.

Thanks

What shop do you own or are you just an employee?

Check out www.speedtalk.com. cncblocks on there crys all the time with people that dont agree with him. if you do disagree then he slams you for not having cnc equipment, a machine shop or just being an "assembler" LOL.

is it really that hard to push a button on a cnc machine??? old bastard carl can do it anyone can!

Your always crying about me, Send me your address and I will send you a crying towel.

You don't much about programming and pushing buttons on a CNC machine I can tell your a wannabeeeee for sure. LMAO

I am not the one crying here you are LOL. Just comparing apples to apples here that all.

Reread my posts and stop crying.

Comparing apples to apples here what is your claim to fame and don't cry about the question I asked you LMAO!!!!

so you need a cnc machine to select an oil pump? thats "apples to apples" LOL!

For anybody that needs more info about carl check out his website him and his world blocks friend built together.

. . . I know I don't want to be on the bad side of stockcar5.

LMAO Second that.

Its only a blog not a website not a lot of truth there, We will see how John makes out in court LOL.

Again Comparing apples to apples here what is your claim to fame and don't cry about the question I asked you LMAO!!!!

Not scared of stockcar5 as he seems to be a blow hard as he can't answer a question that I asked but he can sure cry a lot LMAO.

I'd like some towels. Can I get them monogramed?

[powerslide]

Are they CNC'd towels?

[powerslide]

All jokes aside like or hate carl he answers alof of dart questions on these websites
