Yep, you could be correct as well, the engine was rebuilt 15 yrs ago then sat in a garage until we got it. We thought we had it rather clean but we could have missed something. We are just learning this old car, fixing engines and having fun thing. Father and son projects.

We looked at that, just not in the budget right now. Its about $800 to fix it, its about $3000 to go 408

Good to know. We are putting a new crank/bearings in the engine, as well as rods and bearings. My son wanted to do rings as well for the experience altho we were told they were already done. Also what you are saying may explain why it looked like the rods had been rubbing the crank... looked...

So was this caused by low oil pressure or was this the cause of low oil pressure

And here we have it the noise was coming from a rod bearing completely worn out. I also believe it has destroyed the crank would this cause the oil pressure issues as well. It was the # 7 piston, and not the one with the marks on the bottom. We did not check this when we did our build, we...

The bottom of the cap that goes on the piston is touching on a couple of them, but turning the engine over I don’t know how I could touch anything I am confused

So we are thinking it has to be oil pressure related. No noise at all when oil is cold and we have 60 psi of oil pressure. But once everything warms up the oil pressure drops to 20-25 while driving and 5-10 at idle. \ Could the oil be getting to warm and thin? we are running 15w40 now, after...

Thank you for the reply. Yes I did know the rocker shafts have to be correctly clocked. Drivers side notch to the bottom towards front , passenger notch to rear bottom, oil holes at bottom, rocker arms also have a left and right which I have correct. I dropped my heads and cam specs off at the...

Update: Topped uptranny fluid fixed leak ( not the issue still have noise) Checked oiling port on passenger side, losts of oil, not the issue Check cylinder compression, 110-115 on all. Cant think of anything else. Start pulling the engine tonight.

I found this after much more reading. . It sounds just like that noise.

Could this be a Spun cam bearing?? If so what is a gd test to check this without a tear down? Will the compression test check this tonight?

The rockers seem all coated in oil, I hate to do it to make a mess, but maybe I should start the car with the valve cover off.

Morning all We have searched the forums and have only found 2 similar posts, neither one left an answer as to what they found. Here is my info Recently rebuilt 360LA. Pistons/rings timing chain new oil pick up lifters Thumper cam intake 4 bbl carb Valve springs to match cam/lifters valve...

Ok here are our results. First off make sure your piston stop is long enough or it won’t work lol. 2nd the timing mark was dead on. 3rd when your having you son watch the timing light make sure he knows which line lol. When we set the perfect tdc using the piston stop I Made it extra thick. Son...

Great I will try that tonight
