Are you using springs from Comp Cams? I'd be wary, aftermarket 258/4.0L cams are know to wipe out lopes in less than 10k miles with too much spring pressure. I've got a Comp Cams camshaft and used stock replacement springs and have had zero issues in 25k miles.

Too bad you couldn't access a 4.0L for parts. I'd slap on the timing cover and cam bolt (built in cam button)

As it turns out, i'm using the stock springs after all, the retainers i bought made the installed height of the new springs 1.625 which is a bit short

Got all the major stuff done, just need to put in the radiator, fan, valve cover then connect random hoses and it should be ready to fire up  ;D

Got it running today, needs some carb adjustment but otherwise it seems to run good

Does anyone know if the AMC V8 5/16 pedestal mount rocker arms are interchangeable with the straight six? Seems like the closest thing i can find for roller rockers are harland sharp and they're specified for the 4.0 and studs, not to mention $100 more than some of the rocker arms for the V8s

I was changing the jets monday night and somehow the needle completely vanished so hopefully the new needle and seat i ordered will be here tomorrow

Also figured i might as well use the new springs so i ordered what SHOULD be the right height of retainer, installed height with the wrong retainers was 1.625 and they were supposed to add .045, so i found some that are supposed to take away .030, should put me right at 1.700 which is the suggested height for the cam

Well back to the drawing board, apparently there was coil bind on the stock springs which wore pockets into at least one of the lifters, probably more and probably messed up the camshaft too

Also for what it's worth, my interpretation on the heights of those new retainers was wrong

Ordered the crower baja beast and one of crowers spring/lifters/retainers sets, hopefully everything will install at the right heights and i won't have any more issues  :'(

Pulled the cam out today, as long as i get the new valves, rocker arms, and gaskets tomorrow i should be able to start reassembling it

I think the only thing that won't be new in the valve train will be the locks, which only have those few days that the old new cam was being used for on them

One of the lobes on the old cam



One of the old lifters, some were worse, some looked usable still if this were a post-apocalyptic world where lifters were hard to come by but since it's not, i won't use them  :rotfl:



Head is put back together



New one piece pushrods, chromoly and .020" thicker wall if i remember right, new on top, old on bottom



New cam and lifters



Also the new springs went on at 1.75 and for some reason the cam card only shows installed pressures, not heights but the installed closed pressure is specified at 100 lbs and at 1.75 it would be 94 lbs, close enough for me  ;D

Got it running again today, only took the weekend instead of a weekend plus a few days like last time  ;D

Somehow i always end up with exhaust leaks though, even on different cars  >:(

I feel horrible. I didn't see the post where you got the Crower cam when I was telling you to use the stock springs. I only saw the post on the first page when you were looking at the Comp Cams camshafts that had less lift than the one I have. The Crower would have coil bind with the stock springs as you found out, unfortunately. I hope you don't punch me in the jaw if we we ever get together at an Eagle meet.  :boxing:
