So I needed a bigger truck to hual my 16' double axle trailer. And preferably 4wd, as I live in northern AZ.
I ended up with what I thought was a '93 chevy 6.5l turbo diesel. Or so I thought. There's no turbo. It has a 2004 4L60E
Transmission. I finally found some numbers on the block. So what I really need to know is what engine do I have?
#1 cylinder stamp is 4YY3 505. All other ones could be aftermarket. I'd appreciate any help. Thank you.

Should have been a 6.5 turbo.
Your engine looks like a 6.5 n/a "P" (DS4 IP) and they were available with a 4L60e.

Thats a P engine. 155hp non turbo 6.5 they came with the 4L60E in some 5 lug trucks. What model truck is it in?
