So yesterday was a damn roller coaster . We got the car strapped down being that we did 99 percent of the driveability at my house we were sort of ready. Brian checked the map . Let’s make a pull .
3.33 pulley / 8 inch lower . Make a hit to like 5800 and just let off . Car makes 600 to the tire on the button first shot . Clean up the fuel some pull it to 6200 it makes like 606 but it picked up big in the mid range . We’re talking about pulleys . He goes if we’re putting the 3.12 on it let’s do it now this way we can just keep going and we know it’s safe up there . So I start the pulley swap and of course for the first time ever it’s fighting me . I can’t be doing to much so thankful I had my friends there .
I’m holding the radiator pipe and hose ends back to get the pulley off and boom the hose tears at the t stat housing . Great . We fix that . Get it together . Make another pull . 655 on just a pulley change . Clean up fuel some more Make like 670 . Just start getting Into the timing table put fresh plugs in . Make a pull to 7100. 705 . Make another pull 7200 715 .
Put fresh plugs on it . Start it all hell breaks loose it has a dead miss . Check ignition no issues . Pull all the plugs start just checking compression with a finger and 3 cyl feel dead . Pull intake valve covers check rockers and the valve lash was actually getting tight . We loosened them up and boom we had compression again. So we re set them all 1/8 turn passed zero . Make 2 pulls to 7000 again and have the same issue on 2&6 . Mind you first pull 715 backs it up . Second pull 721 .
So long story short we do it again this time we barely put a 1/16th of preload in them . Also tear the upper to lower intake gasket . Thank god Craig radovich had an old one in his shop we sort of had to salvage but It worked . Fire the car up . Rockers are quiet and happy being that loose . We make another pull to 6800 . Brian adds some fuel and we make 726 . Unstrap it . Take it on the street make a hit and it’s just stupid. I come back
eating grin . Has a small header leak might need a gasket .
The rockers we are not sure what the Deal is . We’re thinking hopefully these lifters like this loose lash and my engine buIlder had the wrong info from the start . Seems ok after driving it then taking it off the trailer . Starts up 100x better too
Speaking with Jim Chahalis and Brian they had another set that a few would get stuck in a certain spot , after they pushed on them
Manually they never had an issue again . Keep an eye on it but all is well now .
