That cam seems like a good match for both combos described above. In fact, i was considering it as an upgrade for my 350. However, i know of a couple of combos using it, and none run very strong. I honestly don't think it has anything to do with the cam...but i've never seen one run strong. Hopefully someone will chime in set the record straight.

yeah ralph, i just want something with a bit more grunt. i am still new to cams etc.....but from what i heard, more duration is more power.
not many guys use the ZZ409, but on paper it does make sense that it will make more power then the 219 with my intended mods.
yes i am ****, i just dont want to fall short of my goals, and if a ZZ409 will give me more push then a 219, then so be it.....

IMHO, you wont be able to see a lot of difference powerwise in cams unless you jump 8-10 degrees +-@.050 minimum. I'm betting that the hp/tq. numbers in general with like components on most L98 "street cams" run pretty much alike. .02

The 219 is a proven cam with the SR. I've seen that cam work well in 350s all the way up to 420s. The ZZ409 looks like the next logical step up, but it's probably not going to make much of a difference in performance and it will be a little more radical (idle, emissions, etc). It depends how much you want to push the envelope. I dont necessarily think it's too big, especially if you're trying to squeeze everything you can outa the combo, but there will be some trade-offs. Like i said above, i was considering it as an upgrade for my 350 combo, but i was willing to live with the trade-offs in the name of performance. We are only talking about 5-6 deg in duration, so any differences will be relatively small in the grand scheme of things. So agian, it depends on how far you want to push. The 219 will give you a noticable lope and mine idled somewhat rich due to the overlap. The ZZ409 will push that a little further and if you're willing to live with it.....go for it. You might consider adding a 1/2 point to the CR if you go that route too. Good luck.

im in the process of swapping cam out my zz409 for a zz-x cam. i do drive my car on the street but only about 2500 miles. the zz-x is big for a street 350 ci. but i want to make the most hp i can and not concered about low end loss or idle quality. it will still make in the area of 14 in of vacuum at idle. zz409 made 16.
to get back to the subject. i had cam zz409 cam in my ported tpi setup, only for 500 miles, but it ran strong and i dynoed at 345 rwhp.
and the idle was very mild for a cam that size.
i am also running close to 11/1 comp ratio.
good luck with your choice...

The 219 cam is the way to go with a SR motor. If you are looking for more grunt have your heads ported and your SR ported as well. I think you will be sorry if you stray from the 219. My opinion is based on my previous cars and cars that I have helped build. You can't beat the 219, SR, good headed combo.

o.k. thanks i am aiming for 10:1 CR anyways, I will have to shave the heads a bit anyways because they are 62CC, May shave them down to 58CC and use a thinner gasket, or just shave them down even less and use a stock gasket. i believe my CR stock is 9.5:1, so another 0.5 shouldnt be too diffucult to gain.

i don't know if the 219 cam is the best for the SR just because LPE says so 
i will say this though.... 383 stroker, AFR 195 heads, ZZ409 cam, 3500 stall, 3.07 D36, on a stock tune pulls 11.7's at 119 mph.
i think that combo works good. BTW this is my friends 85 vette and i think it still has some left in it with a good tune.

i will prob be going with the 219, looking at scorp's dyno # with 113 heads he got 390/445 without a tune. those are good # man, and i have better flowing heads that you would think are worth at least another 15 chp on top of that, and i am getting her dyno tuned.
