i just bought a car and im having some engine issues,it has a 383 with edelbrock heads and comp 1621 roller rockers.,there are numerous issues but i did find a bent pushrod loose,on #6cyl,,I think the pushrods are too long,the adjusters can only be backed off 1/2 a turn in the rocker arm,or is this a non issue? so there are no threads showing,just the cup portion of the adjuster.pushrods appear to be 8 9/16 long (8.56)
engine specs are unknown but cam is bright purple and hydraulic flat tappet..
