Hey Brian, what exactly does having the cam on a 111 lsa do on the exact same same setup vs having the cam on 114 lsa? Is there any other reason other then having the power come on earlier? Sorry should've pm'd this.

Bigger valves tend to "help" this scavenging, but the combination of the bigger L92 valves and narrow LSA don't tend to create addtional torque, just less horsepower.
I've not ever spoken with this customer, he ordered the heads through a dealer, but I heard the car made 530 RWHP with issues, and he is sorting them out and is going to get back on the dyno.

Thanks a lot for finally responding. That helps me understand why my car is making so much torque for only being 346 cubic inches. I too have the larger valves to help make up the hp loss of the tighter LSA cam. Louis did a hell of a job on my car. Can't say enough about him and LG Motorsports staff.

If you ever build a nice setup on your own, you'll probably realize that **** doesn't always work perfectly at first. You'd be surprised at how much little **** that doesn't go right can **** you off so much.
Now if you just pay someone else to do it, then you never know any better...

I have built several "nice" setups of my own... by myself...
In the world of engine performance no news is bad news...
