If you want a smoother idle, look for a cam with a wider LSA. I believe something in the 112-114 range would work for you.

It's not bad. Gives up a bit over stock from off idle to 1500 which is where it's advertised to come on.

It rumbles around my small town with ease & rarely sees 2k till I hit the highway

It idles before & after mass-air conversion at 750 & has a noticeable 3 second lope. You can literally count it off, but you have to pay attention to really notice.

It runs very hard up till fuel & tune cuts off before what I've learned here is about 5200 though I've never let it run long enough to get there.

It pegs the speedometer easily & WOT on ramps & passing are a blast.

I would suspect with your lighter truck & less hp eating transmission you might could do with more. Or less, but I don't know.

Conaski says my 512 is only slightly more aggressive than my stock 5.8 cam. (which I could give you maybe. New set of lifters & you'd be golden)

But in my warped filing system, I can't locate the actual numbers right now.

First pic crank snout side & second trans side or vice/versa?

Hard to say either way. Doesn't look too excessive.

I'd ask your machine shop & maybe see if a trans shop would look at the torque converter for swelling/distortion.

Probably normal for 200K, compare the wear to the other mains. If they're not in the copper, then you've got excess pressure in the converter. I went through one roller 5.0 that ate all the way through the thrust and had started rubbing the saddles with the counterweights.

OK I didn't see the notations. Looks like the chamfer on the trans side has some excessive thrust wear, but not totally eaten up.

200k seems good.

I edited that post Dave.
I’m thinking that same cam you used also why the 1.7 rocker versus 1.6?

Got a hole in block don’t know what it’s for so didn’t paint it? It’s on the left side out side the oil pan

I think it's a dowel hole for when the block was machined at the factory.

The 1.7:1 rocker ratio gives you about 6% more valve lift across the full range of valve lift. Depending on the rest of the intake, it can net some small power gains.
