I used the search function for info, and really only came up with more confusion
The 72 GMC Sierra Grande that I just bought has a 350; presuming it hasn't been replaced with something else, the SPID code is 1LS910.
This seems to be the only car I've ever had where I couldn't just look up the year and model and get an answer for plug type.
What are the basic plugs I should use? Same with wires, distributor cap and oil filter?
From the pic, is there anything non-standard about the engine? I keep reading about 'Vortec' heads and other things, and have no idea what options there were or what to look for.
