What did you do to your NNBS GMT900 Tahoe/Yukon Today?

w00p w00p
"head flow clinic" on youtube ftw.
I went into detail what was done on my build thread (link in my sig)



still lots of work left to do, mostly making them match and some cleanup of the tooling marks.

so far 68cc chambers!
i think by the time i'm done, 69cc!

that gets me into the safe area.


The suck part, i still have another head to do once i finish this one.

What kind of funnel do you guys use for the trans fluid? Just curious.

These: https://www.amazon.com/gp/product/B07RR956HS

I also use these to add/fill the motor oil in the vette.
No fill cap in the aftermarket valve covers i have, and i have intake stuff above the pcv adapters, so they work fantastic.

aah, ok I was thinking something completely different. That's just a matter of another conversion

I think it was only on the LQ4’s and LQ9’s. And some 02’s had dbw and some dbc. Just wanted to get it out there that dbw wasn’t just a gmt900- up feature.

Could also be early 02 and late 02 meant dbw or dbc since it was a mid year switch. Just like the.mid year swap of obs/nbs body style--maybe.

I was wondering what that was too (dbw dbc).
it all makes perfect sense now.

My buddies 2001 Suburban is a DBW.

I'm not sure of the build date though.
