Trevor 326 Posted July 3, 2013 Some lifters will go hard, so probably best to replace them all Share this post Link to post Share on other sites
bear351c 10,270 Posted July 3, 2013 If the base of the lifter is cactus, so is the lobe on the cam........ 1 revhead reacted to this Share this post Link to post Share on other sites

Trevor 326 Posted July 4, 2013 we run anti-pump up lifters and chrome molly rods As an aside, do you have a high flow oil pump on it? 1 revhead reacted to this Share this post Link to post Share on other sites
revhead 1,392 Posted July 4, 2013 new stage 2 cam lifters ,new double row timing set ,or pete jackson gear set, new lifters, case hardened rods, all set to rev again Share this post Link to post Share on other sites
ILIED 316 Posted July 4, 2013 Soft valve springs equals valvefloat. Valve float equals bent pushrod. You can replace the rods with better ones, which you should, but prob be advantageous to put some decents springs in it. 2 revhead and Trev Vaa reacted to this Share this post Link to post Share on other sites

Trevor 326 Posted July 11, 2013 Don't forget to replace your lifters while you have the heads off, you will be sorry if you don't And shit that was a lot of money, but hell if it is better, then all good Share this post Link to post Share on other sites

gerg 10,871 Posted July 11, 2013 Just priced some lifters $120 for the set? and getting a price for some hardened push rods what should I expect to pay for these. Precision International - 17 bucks for a set of 4 US-made Johnson HiLift Hydraulic type. That's 68 bucks for a V8, Probably 90 bucks to your door. Get a cam while you're at it, their Dynotec cams are only $121 and are the same blanks as Crow. Good insurance, otherwise your old cam has to break in all over again with the new lifters....

xebruce 50 Posted July 21, 2013 Put it all back together. Started it up and it ran mint. Had it running for about half an hour. Turned it off and when I went to drive it home a couple of hours later it was running like shit when I started it doing excactly the same thing it was before I pulled it apart.
