I hope that I am not pushing my luck with so many dumb questions... BUT...How do I go about telling if a 235 has hydraulic lifters or not? Are they a plus or a minus.I have had people comment both ways on this topic.( note,I have no problems with adjusting valves)As always ..thanks

With out removing the lifters and inspecting it would be necessary to run the engine at a hot idle speed.Push down hard on the adjusting screw side of the rocker arm.This will force some oil from the lifter causing it to collapse slightly and clatter.Also the hydralic lifter engine will be relatively quite hot or cold.The solid lifter engine will clatter more during the warm-up period.
The 1954 hydralic lifter engine had a higher lift cam shaft and stronger valve springs - produced more power from 3000 RPM and up.The solid lifter engine had a low-lift camshaft with better power under 3000 RPM - however differences were not that great.
The most common problem with the hydralics is that some will -when worn - have a lifter or two that will loose oil when driven for a longer distance at high speed.Replacing the lifter will usually help.
Solid lifters can be installed in a hyd. engine but camshaft requires changing also.
A Power Glide does not sound good with solid lifters as the engine speed becomes much more noticable when driving at lower road speed due to converter slippage.
The Power Glide engine will have a Y or ZE at the end of the engine number stamped into the ledge behind the distributor.
