YES it does and it is a roller cam and hydraulic lifters.
Yes it does.
yes like 350 engine
it could be a faulty gage or a bad oil pump
It is in the Distributor.
Could be, Out of adjustment Worn camshaft Worn lifters Worn pushrods Worn rockers All of the above.
The only one I can think of is the exhaust Y-pipe may not fit from the 305 to the 350.
yes
That would be the 4L60E
Yes, but you must keep the lifters with the cam they were originally used with.
If a lifter is stuck in the lifter bore and won't move, it has probably ruined the cam. The procedure would be to install a new cam and lifters.
