Re: could cam be wiped but are lifters ok?
i realize that this post may make me seem like i dont know about the do and donts about cams. i know that you cant reuse lifters. i have all of the valvetrain on a tray to fit back into the assigned lifter bores. it just seemed that the cam might be wiped by the way it was acting. the engine is a vortec headed 350 with a newly rebuilt quadrajet, new accel HEI distributor, timing set at 10 degrees (have experimented with diffrent settings). it accelorates up to 35-40 nicely under cruising conditions. after that it starts to run rough. full throttle is out of the question. the lifters look great so i assume that the cam is ok. when i get it buttoned back up, i plan to take the quadrajet off of my running truck and put it on to see if its a carb problem. could it be unadjusted valvetrain? i tried to do the hose in ear adjustment but it seemed that there was a slight ticking on all the rockers no matter how much i tightend them.
