Hello All, I have a 1958 235 cu. motor with a 1962 hd that I just rebuilt and I am having trouble getting it started. I adjusted the valve clearance to 0 lash as it specifies in the manual. I have spark at the points and the timing ball is on the pointer. I even moved the rotor 180 degrees out thinking that I might be on the exhaust stroke. I can' get the engine to fire at all. how can I tell if I have mechanical or hydraulic lifters? Any ideas? any and all help is greatly appreciated. Thanks....Oldred

In 1958 all passenger cars had hydralic lifters and trucks had solids.The engine number stamped into the block on the ledge behind the distributor will identify the engine.
The hydralic lifters are best adjusted with the engine running.At this time adjust the intakes to about .006" and the exhausts to about .013" and see if it starts.With these settings it should run with either lifter type.If it starts and runs give it a little warm up.Then slowly turn down the adjustment 1 and 1/2 turns on one of the intake valves.The engine will miss a little if it has hydralics and then straighten out.If it has solids will continue to miss.The other thing you can dO is press down on the rocker arm push rod end.If this causes the valve to click louder (as oil is forced out of the lifter) it has hyd.

Chevgen, thanks for the information, I forgot to mention also that I have little or no compression on #1 cylinder, is that due to the valves being out of adjustment?

Yes, a valve could be too tight.
