What is the stock LS1 engine angle? I am curious what the engine angle is of an LS1 engine sitting in a Camaro/Firebird, Corvette or GTO. Does someone out there have an angle finder they can put on a straight angle on the head or maybe on one of the pullies in the front of the engine?? The measurement would probably need to be done on a level surface (like in a garage) and should not be done on an engine or car that is half taken apart.
Thanks! -Dave

I'm no expert but it seems to me it doesn't matter all that much. You just want to match the pinion angle of your differential as far as I understand it. There's a lot of discussion about this around. I saw a good illustration on the Air Ride Technologies website in the air bar installation instructions. Hope this helps. Don

I recall quickly checking what the engine angle was, I recall it was about the same as when I measured the end of the trans for pinon angle. Just at a right angle to the reading.
update..
I just took a quick measured on the top of the valve cover rail, fuel rail, and along with the Trans output shaft and front pulley.
.. mine came to 3 deg... all around

Angle relative to the rear end pinion angle is one issue, but I would imagine these engines are also designed to work at a specific angle relative to the ground. For instance, the engine won’t run very long upside down… it’ll starve for oil. I am worried about air/steam pockets forming in the coolant system, specifically around the rear #7 and #8 cylinders. If I would have had more angle than the stock setup, I would have used the LS6/LS2 style steam tube rear block-off plugs. However, since I have less angle than 3 degrees, I think I am going to run the regular front and rear steam tubes to prevent hot pockets from forming in the coolant system.

BTw, thanks for the measurement!
