6.2 Dimensions & Capacities

[Vaughn MacKenzie]

I am fixing to do an oil change on my Blazer but have no clue how much oil it takes. I picked up a case if Delo 400 so I have plenty on hand, aling with a Napa Gold oil filter (is this an OK choice?).

There is no onwer's manual in the rig. Is there a website or a page on TDP that lists the specs of the 6.2 such as bore, stroke and everything else? Heck I don't even know what the dispacement is in CID.

Lastly I forgot to get a fuel filter for this beast. It's mounted on the firewall with a petcock on the bottom. Is repriming a PITA after a filter change?

Thanks for answering this newbee's many questions :D

well i'd start with 7 qts and then start and run it for 20 -30 seconds shut it off and let it set for a little bit and check it.my old 84 6.2 took 7 but my 92 with the 6.5 takes 8 so you never know.as for size cubic inch to metric conversion is litres x61 so 6.2x61=378.2 but they are actually 379 or 381 iv'e seen both used but what the actual is you would have to get into bore and stroke,bore being pi(3.14)x radius squared x stroke times 8 .so if bore is 4 inch the radius would be half that or 2,squared which is 2x2 or 4 times 3.14 which is 12.56 x stroke of 4 is 50.24then x 8 cyls equals 401.92.

stroke is 3.81

[Vaughn MacKenzie]

If the bore is 4.00" and stroke is 3.81" that comes to 383.0 cubic inches.

No web pages with exact specs?

[Old6.2]

The bore should be 3.980".

my 4 inch stroke i was just using as an example.

As far as the filters go, there is one on the firewall, which is the primary, and there is also a secondary filter under the air cleaner, behind the intake. You need to take off the three bolts that hold the secondary filter to the intake. I don't re-prime after a filter change, I just fill the filters and housings with fuel, and it always fires on the first try. I have an 83' k-5 6.2
