Guest Posted January 4, 2001 Share Posted January 4, 2001 I figured I would move this over to this part and start anew as the crank Plastigauged out properly...I only did the one journal, but logic dictates that if one is good, then the others should be fine...Back to valvetrain..<BR> I got ahold of the cam and lifter supplier for Buick Specialist and my machinist...take note: the 56 up type lifters SHOULD have .020-.030" preload...and since I can spin my pushrods, I am apt to believe Either I have a short cam. The 56 specs I got from them are as follows: lift- 420@ valve,duration- 196...I am going to call them later today to dbleck if there is anything else to be noted. The guy suggested I can shave the rocker stands .020-.030", but before I do this I am going to put the .015" steel shim head gaskets in and see where I get. Does anyone have an old FelPro gasket floating around so I can find out its crush before hand so I know approx. how much I am going to gain as far as the gskt....<BR> The rocker assys come into play as well as these are reman. units from B.S. also.<BR> Does anyone make adjustable rockers for these or have a pair of assemblies I could BORROW to try my theory....did put the longer pushrods in one hole and it killed the hole...valves dont close...ran it for a handful or seconds...valves didnt hit anything as far as the pistons...lots of room!!! Did compression ck...167-175 throughout...I should also pick up a couple horsies with the shim gaskets.<BR> Do any of you have any further ideas???<BR> The bottom is getting closed up, I couldnt get to the lock bolts with a wrench...I was lucky to get my fingers up there as they are facing away from me as installed. Im open for suggestions guys.....Drop me an E @ firstname.lastname@example.org<P> This is getting old real fast....<P> Thanks as always, don55 Link to comment Share on other sites More sharing options...
