NEW ENGINE IN BUT SAME PROBLEMS !!!

New engine in that has 30k on it. New out of the box Comp Cams ll " 550 lift with 270 duration" New out of the box Comp Cam recommended springs, High Volume oil pump, and a new set of 16 Lash Adjusters , and new plugs .And a new Cluch and pressure plate with fly wheel re faced. Sound fricken Awesome Untill i get up around 4 to 5k And my lash adjusters fail. But come right back when i let off it.. And No,, I have not lhad the money to but my Tuner yet.. Comp Cams sead that thay had not had any reports of lash adjuster problems with 550 lift with hydralic and say dont have to go solid untell you get to 600 plus lift.... What now .. give up and by chevy ??

I used the pick up tube that came with the high volume pump. Used oil pan off the motor I pulled. All clarence and tolerences is what Ford set in the motor because I have not messed with them. Oil pressure is normal on factory guage. Using 5-30 Valoline oil.

Under heavy load mid to high rpm, it starts sputtering, the gear shift violently wobbles back and forth, and multiple knocks, tings, pings...whatever you want to call them coming from value train. It quickly subsides after a few moments running at low rpms. Now and then a soul lifter (lash adjuster) is slow to come back, and a lifter knock as we all know is a lifter knock. In my old engine it would easily and quickly happen under high rpm. And it would continue long enough to where I could get out and broom stick a value cover and confirm lifter knock. When I got the car several months ago it had Comcams stage 1, not sure of lifter duration. Could it be that the previous owner put the cams in and didn't have it tuned causing it to behave as it is and that's why they got rid of it? It's not been tuned yet since I've switched motors and it's running rich enough to burn your eyes. The only reason I know whats in the previous motor is because I've had it apart. The reason I say comcams stage one is because when pulled it would pull real hard. And after seeing the cams stage 1 & stock and comparing to my new stage 2 cams I can see 3 distinct differences which reminds me to go out and get the numbers off of the cams on the old motor just to double check what type they are.

been looking at tunres now. and i see that timing can be tweeked at 4k. thats when mine falls on it face and lash adjusters fail.
