502 V8 in a Reg. cab GMC 3500

[R Dogg 56]

So today I'm at the fuel pump and an old farmer pulls in the stall behind me. Being a fairly nice guy, I say hello. He says howdy and starts to fill his tank. I mention the fact that he has a nice truck, and he thanks me for the compliment. Brand-new 2003 GMC Sierra 3500 reg. cab, longbox, pewter color, Ally.

 

I ask him if it's got some guts to it (which I know it does), and here's where it gets confusing:

 

He says "Yeah, that 502 will light up the duals all right."

 

 

HUH?? WHAT ??

 

 

I was sure that the standard big block V8 from GM was the 496. not, the 502. But why did he say that? Maybe he was mistaken....or maybe I was.

 

Anyone know if the 502 is an opt. in 3500s? I seriously doubt it, though.

[TXDMAX]

No, you're right it is a 496. There isn't a 502 available from the factory on that truck.

[RyanbabZ71]

if it is a 502 he had it installed after the fact. The 502 is a crate motor

If it is stock and he thinks its a 502 he is smoking some good SHHHHHEEEEETTTTTT

[R Dogg 56]

That's what I thought. Now I wish I would have asked him to pop the hood and have me a looksee.

 

Ryan, that link is sweet ! I'll take one of each of the crate motors

 

"Yeah, that Mark 6 will light up the duals."

Isnt a 8.1 really a 502. Kinda like a 5.7 LS1 is really 346 ci? Hes an old timer. Maybe he was just going by what he knows the 8.1 signifies.

The 502 is an 8.2 liter. Some people wouldn't know what engine they had if it fell on them

[RyanbabZ71]

the 8.1 is actually a 494

[R Dogg 56]

lessee here...

 

61 cubic centimeters equals 1 liter. So.....8.10 L x 61= 494.1 c3

 

496 c3 / 61= 8.13 L

 

Which is it? 494 or 496 ?

If one that big fell on me....I wouldn't even know my name, much less what size it was.

The 8.1L/Ally combo is a 496 Cubic Inch Big Block Chevy.

 

With the Torque Management program from GM I doubt it would just "fry" the tires...

Bore and Stroke for a Vortec 8.1 is 4.25"x4.37" (107.95 x 111.00 mm)

 

So capacity in cubic inches is (4.25/2)² x pi x 4.37 x 8 = 495.95

 

In metric: 8127cc or 8.127 litres.

 

The 502 is a competely different animal with a larger bore and shorter stroke (4.466" x 4.00").

 

Hope that helps.

D**N, SON !!!!

 

You're gettin all sorts of technical on us now.

 

I could care less if it's really a 494 instead of a 496. As long as it's not a ECOTEC I-4. Ooooo, scary !

 

Yep, it helps. Thanks a lot !

Don't mess with an old farmer that says he can "light up the duals"

[HendyPhoto]

Old farmers are old and they are farmers.

my friend and I (we're 20) are always joking about this. We call it cock strong, you know the kind of guy that couldnt bench press 200lbs but could pull up a pine tree and beat your @$$ with it
