Great! Thank You Sir!
I listed only the differences between the two motors listed.
I ask the tuners in the crowd, although they seem small:
How do you see these differences effecting a tune?
Do you think these differences are what gave the L33 the 15HP over the LM7?
How do you see them effecting a Blowers output.
LM7 Left - L33 Right
Both are 2005
Compression Ratio
9.49:1 9.9:1
Camshaft Lobe Lift - Exhaust
6.96 mm 7.2 mm
0.274 in 0.283 in
Camshaft Lobe Lift - Intake
6.82 mm 7.2 mm
0.268 in 0.283 in
Valves - Valve Lift - Intake Valves
11.58 mm 12.24 mm
0.456 in 0.482 in
Valves - Valve Lift - Exhaust Valves
11.82 mm 12.24 mm
0.465 in 0.482 in

hp tuners . I learn a little every day. I have slowly bump the timing up and no ping yet it should be 87-90 today cant wait . Next is trailblazer converter, thorleys, and magnaflow . A friend has an 05 hpp3 but they realy don't change much in 87 oct tune .
btw I average around 17.8mpg to 18.7mpg. average driving 45 to 65 back roads with at least one run per day floored 1st and 2nd .
The Rock did you get your tune yet ?
