Hey Bob, I'll send you a DM with my contact info, would love to take you up on the offer for the connecting rod!

Right, figured! Ok will get to work and get back to you on progress! Thanks Bob.
Bob, I'm not clear that turning the journals is possible without pulling the crank (and pulling the engine). Do you have a suggested easier option for getting this fixed without pulling engine or...
I'm confused, thought zinc was necessary for break in, and flat tappet cams. Used with Rotella 15-40
Springs were new and matched to summit 8600 camshaft. 3angle valve job with new seals.
Thanks so much Bob! I may take you up on the offer. I did not replace the rod bolts, and in hindsight I will. Rods were magnafluxed, so my initial assessment was that a rod bolt failed.
AMC friends,
I built a 360 last year, and threw a rod through the oil pan a few months ago. I had just changed the oil after a few hundred miles and added zinc in as prescribed.

Guy in town will only sell me a pair, wants $225. Surely I've got to find a better price?
Do you guys know if I need to match the 502-2 heads? Or will other heads match up ok with my other head?

Can you see this crack? Running 45°
I thought the same thing. Heads are 3220502-2

Jim, I got the head off, but don't see anything out of the ordinary. I looked for cracks, but don't see any to the naked eye. Is there an exact spot to look?
I'll be...
Ok, will be pulling the head today and checking all of the above. Plan to get the head back to the machine shop to check it fully tomorrow.
Bob, quick update, got new head bolts from this great engine shop in Belmont. $15. The 14 bolt had a good amount of white coolant on it when I took it out.
Installed and retorqued in order in 4...
That's the plan, I'll be pulling the head tonight. Clearly fresh coolant leaking pretty good between head gasket and block on bottom side. Will get head to machine shop tomorrow.
Should I be...
Thanks Bob. I did tighten in factory order and with progressive torques, and the heads were checked at the machine shop. Nonetheless, sounds to be a common problem that matches my symptoms. Only...
So I tore down an old 360 and had it machined 0.030 over, crank 10/10 , new camshaft and lifters, new springs, heads done completely.
Got it running for about 20 minutes to break it in and seemed...
Thanks Bob that's great to hear. The machinist is doing a full valve job on the heads with upgraded springs, so I expect it to be a strong engine.
Any suggestions on exhaust? NC doesn't have much...
Also, with the price of the cometic being so high, we are just going to deck the block and use the standard head gasket.
Bob, I'm running the Summit k8600 lift is .497 and duration 224 at 0.050.
t176 4 speed, I believe the gears are 3.73.
Edelbrock intake, 1406 carb (600cfm)
I figure this is an around town cj7,...
Bob, thanks so much for the quick response!
You are right in saying that I won't gain much, but from what I understand even a little compression bump will help with a more aggressive cam. Both...
Hi Bulltear folks,
Does anyone have a good source for this? I found one option here: http://www.innomach.com/images/2012-IMS-CATALOG.pdf
at $35/per head, but don't know anything about the shop....
