Yeah I'm just swapping cam, but with more airflow I might be better off keeping the 799's... Or not? I might add a tune to it eventually also.

 

Keep the 799's, best stock heads out there.

Also there is no "might" add a tune, it's a "must" do a tune. No matter what, if you swap camshaft the engine needs a tune. They do not self learn or self tune for changes made to the airflow model. All airflow and fueling calculations will be incorrect if you swap camshafts so a tune is required.

 

It's not likely that you'd have LS6 springs from the factory. Most have the 12589774 which has a max lift of .520.

 

It would be nice if these guys would set up the test engines for the real world, using a streetable camshaft for either a muscle car or one designed for a truck and run the same compression ratio to eliminate as many variables as possible. I enjoy doing such tests and reading about them but this one I think is flawed because of the compression ratio differences.

 

Yeah I wish they would’ve done the doggon 07 and up intake instead of that Fast unit.

 

Brian tooley did that with a cam called low lift truck cam.
. 500/. 500, 115 lsa, 224/230
they claim HP gain up to 66 HP.
No hardware change required.
Numbers are very similar than the lh9 cam.

 

I meant a head test but using the truck intake.

 

I hear you now

 

Isn't that an AFM/VVT camshaft?

Crane developed a Gen III camshaft that made near 50 horsepower over stock with a 200-200 duration, same lift on a 113 LSA.

 

No afm just vvt, 1 bolt can, 4 x gear
