224R cam...thinking of maybe 110LSA

How much overlap do you want to run? TR also has a 226 lobe (listed as a 227); You could do a TR 227/227 109 and run about the same overlap as the guys running 232/232 112 cams.

You'll see what I mean.
I find this cam interesting. My cam is almost the exact opposite. More duration, less overlap, more lsa and higher icl. I think it would make 400rwhp with a lil more tuning, all the bolt on's, and open headers. I would rather have the 224 110 106 cam because of all the torque and similar hp at lower rpms.
How much does the 110lsa hurt drivability and mileage? Can the engine be lugged around at 1k rpms in 6th gear like my 230 114 cam? The numbers almost seem unreal. Maybe they are since open headers add about 15rwhp.

This will go in a street car that will see maybe one or two days at the track in it's life (Of course, it will see a lot of country road showdowns...). So, low-end, stoplight-to-stoplight, torq is of prime importance.
I still haven't grasped overlap quite yet, because I haven't studied it hard enoungh, to answer your question intelegently. I know the equasion to figure it, and I know it's of vital importance, but I just haven't taken the time to read a lot about it yet. I also haven't grasped the "ICL" at all, or what the +x number is after LSA.
No need to explain it to me (unless you have a hankering); the information is at my fingertips, I just have to take the time to read it.
This 224 110 LSA cam is interesting. I would love to see a low lift, fast raqmp version. You say TR takes custom requests? I'm not in the market until I SELL MY '94 Z28 (!!!), but all the money from that will go toward my '99.
And Pat G, you know a lot more about cams than me by a long shot, but I bet he wasn't looking for "best power and torque," but a mean street machine.
I could be wrong. In the city, my car sees a lot of 1500-2000 RPM time. The TR 224 seems to make real good power in there, I'm just looking at options. I know that I don't want to go lower than a 224/224, though.

Even with all that working for it, the power and torque die off fast...too fast...this is all a result of too early of an intake valve closing. For best power and torque, 346 LS1s seem to like an IVC of 44-46 degrees ABDC. This one is at 38.

EDIT: Wait. You're talking about the cam in your sig, right? That's not a 224/224 110 LSA. Okay. Nevermind.

Just for clarification, my cam improved my 1/8 mi by 3mph but by the 1/4 trap I only had a 1mph gain. It didn't carry the 3mph gain over into the 1/4 trap. That's why I say it lost power on top. I could be totally wrong in my assumption, but nobody could explain it better.I added 1.85 rockers a few months after the cam & was able to see that 3mph gain in both the 1/8 & 1/4 traps. OK, I'm done with my blah, blah, blah...
