I'm assuming the 224 cam is the most speced cam ever for a LS1. Seem like everyone was running a 224 cam with all kind of heads/intakes/exhaust. I'm guessing cause it's has great power improvements and drive nicely. I'm not sure what duration would be equivalent to a 224 LS1 cam in a 402ci stroker.... but I'm sure some one here knows.

The equivalent would be to add about 10 degrees of duration. That will give you a pretty good idea... so 234/234 or 238/238 or 234/238 would all drive like a TR224 or 228R or the AFR 224/228, for example. This is why something like an MS3 is actually a torque monster in a 402/408. I've seen AFR 205s opened up with MS3s make 500/500 on a 402.

That's an awesome post there Jake.

I have been doing a bunch of research on this very topic, and what I have found is:
1. If you do not already have a set of 243/799 heads, aftermarket castings are the way that you want to go.... used 243/799 heads are at least $400... and you risk them having issues, which would end up adding $$$ for shipping back and forth.
2. If cost vs performance is a concern, PRC 225 as cast heads have made high 480s RWHP on NA stock cube LS1s, and are less expensive than all of the other aftermarket heads... under $2000...
3. If price is no concern, AFR or Mamo heads are the way to go.

Well guys... I emailed Tony a few weeks back, one of the worst.. lol and best things I could have done!
Plans have changed into an LS3 based 418, 11.75:1, and I've pulled the trigger on a set of his MMS 235's... 8019 springs with hollow valves. It'll have all the premium junk, SLR link lifters, YT ultralight M10's... hoping to have it all together by May-June!!

Hey FRiCK, did you ever get your idle sorted out ? Did you try the 230/234 113+3 you talked about in this thread ? Your idle clip on Youtube did sound nasty.
Reason I ask is I have finally saved enough money to get a cam. I plan to buy a custom grind Cam Motion through Colorado Speed and a 230/230 111+2 is one I'm considering. Also debating a 230/228 111+2 and a 230/230 112+3 . So 8, 7 or 6 overlap with the same 44* IVO. Was thinking .620/.612 lift.
You said your version of the Torro was kind of a pain to drive in traffic. Was this because of the lope, the loudness or was it some surging ? I will have less compression than you, around 10.9 instead of your 11.3 and I know that has a effect on exhaust volume and drive-ability.
BTW, congrats on your Mamo-fication .
