If it's possible that it could just be a windage problem at 3000 rpm and above, I may check that first, even if that's not the problem, i'm still better off with a windage tray in the oil pan than without one.

Yeah, and he already acknowledged that he'll check the galley plugs too, as I read it, but then maybe I'm wrong. Been wrong before, and will likely be wrong again but it won't be because I don't read the posts.

well yep.. you are wrong ..but any ways i made the point that a restrictor shut down upper valve train oil .it was something Jerry said but wanted for him to under stand that this block is not the same as some that why i asked for sure it was a shp and not a world block or a wheeler block.GM bowtie. oil restrictors may help with oil psi and less upper oil .but has nothing much to do with drain back from the head if them hole s need to be open so oil runs threw the valley and then pan . a restriction that can be at heads then oil is all in heads and can be in lifter valley as well. i do not think thats it .the valley on the SHP block it is cut out much like a bbc so there places were oil would fined it way back in the pan less heads were pluged then it would fill up till to pushrod hole then drain back . the SHP dart block and M do not oil like a stock chevy they have a lifter oiling cross over leave that with a plug out. you would have a big loss of oil to top end . main s still would feed the bottom end. but would never build oil PSI thats in front of block in valley . intake has to come off to check . it is just like the BIG M dart bbc . then there is still plugs 3 under the upper timing gear as well .the front of the engine has to come off as well less you have a two part timming cover and can see the 3 galley plugs. he never said he was pulling intake or timming cover ? yes i seen he did put on a new pickup never said if he welded it .? someone asked if he check it was it 3/8 or 1/2 ? i did see were he used another oil gauge so i did ask. but more to the point i was looking for him to tell me it was a mechanical gauge and not a sender gauge never said what he used so my fault so what have you added to this ?

this engine needs to be COMPLETELY disassembled to make sure everything is 100% correctly machined/sized/installed correctly---a plan for just changing the oil pan while might be the cause still leaves hundreds of possible combinations for mistakes to go unnoticed and eventually will cause a complete disaster from continuing to run it without finding the cause--------


We have tried to relate to him what the possibilities could be for this to happen and he seems to be mostly doing a dance around with your blessing------------

Jerry, I don't see where I've offered any blessing, nor have I offered any comment on the problem other than to say that Easterner has commented back to both you and Pat, saying "Thanks for your help", and offered that he's got some steps in mind that he hopes might rectify his problem. My point is that he's not asked for anything else, other than a bit of time to check things out and try what he believes might be a solution. In my mind that's a reasonable approach, but I'll yield to you and Pat to solve his problem.

well i under stand he is going to put a pan on .in my brain i have about five or more engines banging around that i am building now at my shop the list one big chief engine max all out effort 632. another 632 drag race pro II heads .a bbc489solid roller engine hot street . street strip bbc496. a.bbc 589. bbc548 blower engine . a ford roots blower engine with the boss iron block 9.500 deck svo main 430cid . 3 sets of dart heads 360.345.345.old set of pro stock 861 bowtie heads i am shure i missing something...yep a tall 10.200 deck 427 with a 4.3/8 crank . a 454 9800 deck race engine to max bore and stroke low cr run on street pump fuel, so if i abit slow or takes me alonger to added to a post two thing s he can do listen to what i say use it if he likes or not

I put the new pan on today and that seems to have solved the problem. At idle the pressure stays at 45 psi and when you accelerate the pressure goes to 55 - 60 psi and stays there. I'll take it to the track this weekend and see what happens. I don't have the know how or the money at this time to have someone completely tear down my engine to check it out, so hopefully their are no other issues with it that will cause a serious problem down the road. Thank you again for all the expert advise.
