Yes, it will work. If the 454 was a tall deck design, you'd need to shim the distributor up .400" to mate with the 350 oil pump shaft.
No, you do not have to prime the oil pump.
Need to know the year and what you are working on. Ask your question again with this info.
350 chevrolet engine
no
YES it does. Must remove oil pan, Oil pump and rear main bearing cap to service the rear main seal.
Good question. I'm looking for a way to prime the pump before initial start-up of a Pontiac 350 that has sat for years. If, I were to have to change the pump, I would be looking at safely removing the oil pan, first
You do not have to prime the pump. Just add the correct amount of oil and start the engine.
It is in the oil pan.
Of course, there is no other way to get at the pump.
How do you prime the oil pump on a 1986 Toyota truck with 20r/22r engine
