The easist way is to have the car on a lift. They best access is from underneath. I've done them from the top but it is nearly impossible to reach a few from the top. VBD buy a flex socket from autozone, its what i used on my 92 with a 350 a few were a little trouble not that bad, a 80 caddy fleetwood with a 368 is harder, only thing to do is use a weekend when you can be patient and everything will work out fine. the hard part is the distributor cap getting it out you got to muscle it a little bit.
In my 91 RS 305, I change the spark plugs working from underneath the car. The spark plugs are easier to see and get a 3/8 ratchet with long spark plug socket on from underneath. How can you do that? is quite imposible to remove it, is no space to do work ?

check for spark at plugs sounds like a ign problem
They are located on each side, front and rear.
try replacing the coil.
(This is from the 91 Caprice service manual for the HEI ignition system) Looking at the distributor cap from the front of the engine bay, and running clockwise around the cap from about the 1 o'clock position, the wire numbering is: 3,6,5,7,2,1,8,4
It is important to gap the spark plugs at the right size. The spark plug gap for a 1981 305 Monte Carlo is .045 inches.
Yes it will, as long as you are swaping from a 305 to a 305.
Need to know what year and engine size.
There is no timing belt on a 305 unless it is an aftermarket belt drive system.
change oil once a month u could get 500,000.
as far as i know the 4.3 is a v6 which is actually based off of the 5.7. gm just cut 2 cylindars off if there is a difference it will be the heat range on the plugs for your info, the Chevy 4.3 ltr in a 94-96 caprice is a 265 v-8, do some research before giving info on engines you know nothing about. oh and by the way, the power rating in a stock 4.3 v8 is higher than a stock 5.0 and also the correct answer is NO, the spark plugs are no different than the 305 or the 350.
