@Robert Winkworth how does the fan pulley bolt to the hub then ? Completely lost on this one

I think the only thing about 24v is the tappets might interfere with fuel pump lobe if you have one? Not 100% sure but I have heard about that. I think 24v tappets are 1.5”, but someone there sells 1.44” ones which allegedly clear the fuel lobe

Ok major updates. First few things, I found difficult to measure the crank mains with a micrometer. Skill issue. I’ve torqued ARP to spec one cap at a time and measured diameter of the crank lobe, then I zeroed my dial bore gauge to that measurement, then measured the main cap (diagonally like the manual says). I had to do one cap at a time because my bore gauge can’t measure deeper than 2 caps. After everything, I dropped the crank in and plasti gauged all the mains. Plasti gauge showed about 0.0005-0.001 tighter than all my measurements. With my freshness, I wonder if plasti gauge is more correct. I’m worried that there is too much clearance on the sides now as well. I’ve also bore gauged all the cylinders. There is a significant taper, but maybe because it was horned with a torque plate?(hopefully) After cleaning the block, I also noticed a line in the cylinder. At first I thought it was a crack, I’ve sent pictures over to the machine shop, and they told me it’s a sleeve, which is something that wasn’t disclosed to me when I got it, just “machine as needed”. It weird to sleeve just one while the whole block is bored 40 over.

@Robert Winkworth This is the measurements with bore gauge, The plastigauge was done right on top as otherwise it would fall down.

@Robert Winkworth these parts

@Robert Winkworth so they they sell them on temu/alibaba
