ticking in my new to me 57 3100

Eng is ticking. Used the old trick of putting a piece of wood up to my ear and probed aroung the eng. When put on valve covers it was quiet. when put on intake manifold you could here the ticking through the wood got louder as I went back tward the dist. Any Ideas, I know my way around an eng but I don't have much experiance with them. It's a 283 last owner said it made the noise because it has solid lifters in it. Next question can I just replace the solid lifters with hyd ones or do I also need to do something else to be able to install the hyd lifters?

If it has a solid lifter cam ticking is common. You cannot place hydraulic lifters on a solid cam or vice versa. The tick you hear could just be a rocker out of adjustment.

First thing would be to see if it actually has solid lifters or the owner was covering up for a noisy valve train by saying it had solids.

Once you know what it has (my money would be on hydraulic), readjust the valves to see if that quiets it down, or if the cam/lifters are too worn and need replaced. If you replace the cam and lifters (replace them both), use a hydraulic cam and do a search here for guidelines on breaking in a new cam/lifters.

The noise does not sound like it is coming from under the valve covers more under the intake man. If the valves were out of adj would they be more likely to make noise at the rocker or at the cam/lifter.

If I do go with a new cam and lifters what lift and duration should I go with? I know next to nothing about this subject. I like the lopey lope sound but this 57 3100 will be a street/cruser machine.

Diagnosing engine sounds over the 'net is like sucking t*t through a cashmere sweater.

The cam and lifters are directly beneath the intake. You'd expect to hear valve train noise from collapsed or out of adjustment lifters up top- but there is no guarantee it's something else because all there is besides the valve train is loose wrist pin noise or piston slap. I suppose the cam bearings might be suspect, but that's a long shot. The distributor wouldn't make that type of noise and you'd hear it through the distributor body if it was.

OK so I put a thermostat in the truck and around 150-180 she quieted down a bunch. Going to readjust the valves tomorrow and see what happens. Better to adjust hot or cold? Biggest question now is why was there no thermo? Have to test drive after valve adjustment and see if it over heats.

The exact reason for why yours is missing may never be known, but overheating is a common reason.
Some guys think removing the thermostat is going to help an overheating problem or make the engine run better. This is false.

You need to see if the lifters are solid or hydraulic. If they're solid, there will be valve lash on all the valves when the lifter is on the base circle, and the lifters will not compress if the rocker adjustment nut is tightened down enough to lift the valve slightly off its seat (also w/the lifter on the base circle). If they're hydraulic, the lifter will bleed down from the valve spring pressure, allowing the valve to close again. This bleeding down can take several minutes, so if you do this go have a coke and come back to see if the lifter has bled down or not.

Hydraulic lifters can be adjusted cold or hot. Factory settings were often 1 to 1-1/2 turns down from zero lash. Nowadays, we usually use less preload- on the order of 1/2 to 1 turn down from zero lash.

Most specs for solid lifters call for the engine being hot. The problem you may be facing if this is a solid lifter set-up, is you do not have any specs on the valve lash. You can start at 0.020" and go from there.

Too loose is harder on the valve train than too tight- until you are so tight that the valve doesn't rest on its seat long enough to rid itself of enough heat. When that happens, you risk burning the valve and eroding the seat.

If this is an original engine, there's a very good chance the cylinder head needs to be rebuilt. These engines were made to be run w/leaded fuel, if it's been driven extensively on lead free gas, the seats and valves can be worn out. The valve guides will always be worn, too. Along w/the valve stem seals being bad as well.
