cam experts please
Im looking at another cam .510 in @.050 230 degrees, .520 ex @.050 236 degrees. lsa is 110.
Currently the mods I have
1. ported and polished factory heads
2. Beehive springs
3. 1.6 rockers
4. 30lb injectors
5. ported intake
6. 52mm tb
7. long tubes
8. no cats
9. tuned
10. 180 thermostat
11. 2400-2800 stall
12. shift kit
Would this cam do ok with this setup? oh course re tuning the computer

That cam looks like it will be in the higher RPM range. Since you said you have a ported intake I assume you mean a ported stock intake. I would choose another cam that's well suited for low and mid range power. This cam would work well with a Miniram I believe.

I would not put this cam in a 350 TPI. I'd go about 10 degrees less on the durations for a TPI-based machine.
This cam is better suited to Miniram and/or more cubic inches.

It's a lt1. I thought maybe with the lsa being 112 not 110 would help. The duration looks to be an issue.

Way too much cam for stock heads and gears under .410s. I would go with a 112 lsa and 10-15 degrees lower on the duration. It's nice to hit the cam choice dead on, but it's much better to be undercammed than overcammed. How much time do you spend above 5500?

lsa doesnt necessarily dictate idle its overlap or valve opening and closing events. 2 deg either way in most cases "depending" wont make a huge difference

My buddy ran a Comp Cam very similar to that in a 4th gen F-body with home ported heads and headers and his own tune. He put down 370+ rwhp. He had an M6 and I decided on the 224/230 for my auto car with a tight 2400 stall and 3.33 gears. You don't need 4.10's for the street. I think 383vette was thinking of manual gears. But then again, we still don't know your goals......

The 110 vs 112 LSA is not that big of a deal. What really matters is the overlap. The 110 LSA cam has 13 degrees of overlap, the 112 LSA cam has 9 degrees of overlap. The greater overlap will cause it to idle rougher but when it hits the power band it will pull harder and peak at a slightly lower RPM then the 112 LSA cam. It probably does not really matter which cam you choose either one can be made to work fine. I would agree with some of the other comments on this thread that it is always better to be under cammed then over cammed so if you want to error on the conservative side error on a smaller cam. That being said I run a 226/230 cam in my 350 and I think it is tame. It pulls fine from 1200 RPM and pulls hard to 5500 RPM. The cam you are looking at will be not crazy in a 350. That is why I asked what you goal was?

If you are just looking for the sound and a little more performance, that cam is what you are looking for. It may not be the best one for max power, but like you said if you are just having fun it will still be better than the Hot Cam.

First, I thank everyone for their comments. I was looking for something on the aggressive side. I do most of my engine work myself, but I'm not a cam expert. Currently the hot cam I have with the 1.6 rockers is tame to me. Worst comes to worst, if I don't like it I will put the hot cam back. No problem for me, I like working on my ride. No real goal, just want to have fun.

I had a ZZ9 cam in my 355 roller engine some years ago, it was sold by TPIS, that outfit in Chaska Minn. well it lasted about 6 months and developed an INTERMITTENT rough idle, even at 850 rpm programmed idle speed.....I went nutz searching for it, over a period of YEARS....thing is, every once in a while it would run baby smooth for a day or so, then back to rough as a cob.....
finally got disgusted with the lack of fuel economy, and dropped in a dead stock L98 cam.....I about crapped my pants upon looking at 6 of the lobes on the old ZZ9 cam......yet the lifters were perfect.....
and the idle has been fine for the last few years now.....
I mention this because the OP's specs looks amazingly similar if not identical to that ZZ9 cam spec.....
and to further the comments, I told this story to another fellow at a cruise in last Saturday.....and HE replied that he had the exact same symptom on a FORD, that drove him krazy same as mine did, and so at least I not alone....roller cam to boot....
he condemned Comp/Crane for the problems.....I have NO clue who made my messed up cam, just who sold it to me.....
