Just to add if you do some research you will find that low LSA cams also have a more peaky TQ curve... They come on real quick but fall off quickly... The lower LSA has a direct relationship to the overlap, when defines where the cam is efficient... lower (more negative) overlap moves the efficiency down in rpm, the higher (more positive) moves the efficiency upwards meaning you spin it higher.... Cam selection comes down to overlap and DCR... The duration, lobes, LSA and ICL all contribute and need to adjusted proportionally... Believe it or not cam selection is a science... I am no expert but i do pick out my own...

Do you run a two piece timing cover? I think I am gonna get one, do you have any leaking issues?
I' m right at 11 to 1 comp also. I find that if you run a bit more duration with a short over lap it all comes together.... I don't spec my cams but I read alot of theory.

TSP 220 581 110
I like it alot i dont really care to spin it past 6500 and it hits hard from 3400-6200.
The idle was a little tricky to get tuned even after the throttle body was diagnosed as dirty, even now it could use some fine tuning ecspecially now that its summer and the ac is on it can dip down sometimes but its not that bothersome i just havent had a retune yet.
Speedo video yesterday... Inlet air temps were about 135 so it was running like ****. I just got done stuck in traffic for 30 minutes with AC on
Also i was getting back on the freeway and i let out is why it shifted a little early from 2nd to third. Lol as soon as i came over the the little hill of the on ramp there sat a tarrant county sherrif
Lol and YES it's still slow as f**k!!
