Here's my handling, side to side leveling, and "custom" alignment spec info.

 

Can anyone point me into the direction of where I can specific technical specifications of the LM7? I have the bore, stroke, cam lift, CR, but I can not find anything about valve diameter, head air flow, or cam timing, etc.

If anyone knows this information or where I can find it, I would appreciate very much.
Thanks.

 

Good reference for the differences between 4.8's and 5.3's

 

here is what i have done to several ext cab's back windows to get rid of the wind noise. first i popped the window arm loose from the latch assembly>>
you can see it still touching here. i pop mine loose with a phillips head screw driver while opening the window.


then i pull it outward and have someone hold it. i drill a small hole in the base of the latch. then i drill a smaller hole in the frame of the door. enough for a screw to start.then i install a screw in the holes and tighten ever so slightly. it only takes about a 1/4 turn and then you are done.
i hope this helps. i can get some better pics if needed.

This thread is in some serious need of orginizational help. Good tips and tricks but, we need a better way to organize them....Hmmmmm.

 

Well, here is a site with some OBDII code info that linhardt sent in. Hopefully in the future we have a better way to present all the info in here.

Hey, didn't I say I was going to do that at one time? Oh yeah I never got around to it.

 

My contribution:
www.speedyoldtruck.com click "projects"
Lots of info for adding things to the older trucks (mine's a 72), some stuff on datalogging, electronics, ECM modding and some other things. Going to reorganize the site (again) soon to separate papers from projects...

 

Good site here http://en.wikipedia.org/wiki/GM_Vortec_engine
