see the problem lies on the fact that he wants factory like torque in the factory rpm range. narrowing out his LSA is really the only way to get any noise without hurting his off idle (unless he gets a torque coverter, but will still hurt torque). a 108* LSA should net him some decent noise. heck, here is a video of my neon with a 204/208 cam set, that at the moment had about a 110* LSA

now i realise that being a significantly smaller motor means that for a given duration, it equates to a larger cam in a larger motor, but you get the idea.

I'll end this conversation right there.

did you read my post at all there bud? obviously not.
camshafts are camshafts, and i was simply using it as a reference to show that a mild cam, with an aggressive LSA can cause the lope the OP was looking for. if you have nothing more to add, or a logical structure to your arguement, then i really agree that you should end the conversation

did i say that? i dont recall writting that, but i am exhausted so maybe it came out that way. no if i remember correctly i put that similar spec'd cams will act like a larger cam on a smaller motor.
but that was not my point. my point was that the OP was looking for a lumpy stock style cam. so keeping his torque where he wants it, but getting noise would require a tweak to his LSA.
i feel like i have already stated all of this already

LOL, that's quite a bit different from what you said. Overlap is the primary factor that will decide how much a cam "lopes." You're talking about a cam with +10* overlap. That's like running my 224/224 cam but on a 117 lsa. They would both sound the same which would be close to stock.
Now with that said. I agree that the cam you picked out would probably work really good with a stock torque converter, but you may want to choose your words a bit more carefully next time.

and i will give you that. though, i bet the OP will be happy if he were to ditch his cats (though he has longtubes so that is probably already done) and go with an open exhaust, it will make some noise, which i consider an agressive lope on a street car
when i am building a street/strip or weekend road/race car, cam lope is a different thing. but i dont sacrifice on the street
actually, now that i think about it, we just put this cam in a SBC (327ci), 9.5:1 static compression ratio, in a 32 ford roadster, with a tripple-deuce setup along with longtube headers dumping through glasspacks
comp xtreme 4x4 flat tappet
advertised duration: 250/258
duration at 0.050: 206/214
lift: .432/.453
LSA: 111*
it loped pretty darn well for a baby cam. i was quite impressed really, and the torque that thing made, again, very impressive for such a mild motor
