Torque converter unbolted, no rocker gear, no plugs, 40lbs. Honestly, for new rings, this feels ok to turn over on the power bar. I'm using std tension oil rings in the Total Seal Plasma Moly series. I might start putting parts back on & testing the difference in drag. I have another engine, 7 years old, has nearly the same springs & thats 65lbs to turn over with the engine complete.

You said it is firing at tdc on #1. But is it firing at tdc on #1 on the compression stroke?

Well, the engine got pulled & stripped & everything rechecked, & rechecked again. It rotates fine as a long block, but as soon as I connect the valve train, it goes bad. So I currently have some weaker valve springs in it & it turns over with the torque wrench at 62lbs, which is a lot better than 120lbs it did before. The motor is back in the car, just waiting for me to add all the accessories so we can restart it. I am hoping after I have done a few heat cycles & maybe a bit of public road rural driving, things will bed in a bit better & then I can up my spring pressure again. The springs I had in it were 640lb rated springs, I'm thinking I should drop this to 525lb rated springs. Only problem is, I have a set of them, but I recently put them into my other street/strip car. Its Summer downunder & seriously too hot to be in the shed during the day. Since we are past the xmas rubbish now, I'm guessing I'll spend the next 2 nights in the shed finishing everything off. watch this space.

[align:center][/align] Glad you found and fix it, what was it? The only thing we changed is the valve springs, the set that's on there now were staunch flat tappet springs. I've fixed the valve cover gaskets, & tightened the oil pump connection to try & remedy the oil leaks & now....the starter motor is having issues. It's a fresh rebuild of a HD ministarter variety. So that's tonites job, pull it off & see what's wrong with it. Can't even jump start with the screwdriver on the terminals. Good grief, I must have p!$$£d off some witch last year & she has a hex on me.

Try the old starter. Maybe the new one is junk I'll leave this here.

My 15-1 572 has been started with the same factory Mopar mini starter going on 11 years. Loos like the middle one in your pic. 310 seat / 805 open. Doug

I sent all my starter stock to my starter motor rep, he checked them all & said there was nothing wrong, but he did suggest the 2kw unit over all the 1.4kw units.
