Good strong cam for DD

[cobrahunter]

Maybe some Cali owners can chime in on this one...

I'm looking to go with a new cam install. While I want it to be a strong cam, if the car can't pass smog, then there's no point. And if I only get lame numbers, again no point. Right now I'm looking into a cam with the following specs:

216/220 .525 .532 LSA114

Here's what I got:
hi flo lid
1:8 comp cam rockers
80mm throttle body
FTRA mod
LS6 intake
shorty headers (I'm in Cali; they do visuals around here so back off!!)
flowmaster exhaust (but usually have cut-out open)

Important, the car HAS to be able to pass smog; it's my DD.

I have close to the same mods and installed 218/218 527/527 and feel it is a great daily driver (weekends). No it won't run with the really big dogs but remember it is a LS1 to start with. Plently of added power when the band hits 3400 and up. My dyno numbers are with two different tuners and fell out very close so feel there are good...not inflated numbers. I am 64 years young and give the rice burners fits when they dare. Good luck

Sorry for the jack, but where are you in Eastern NC? Most all of my family lives from New Bern to Beaufort...

Down town Havelock...ooh Rah!

[Frost]

Yeah have friends and fam that work at Cherry Point, NADEP n schizz....

There is a dynojet in Jacksonville (no GM tuner though) and I have been thinking of setting up a tuning trip down there if I can get enough cars signed up...

/end jack
sorry OP

Im in Cali too and the cam im looking at getting has a 224 duration with a 115 lobe separation. I was told 224 duration and under should pass and anything with lsa 114 and up will

Your gonna want to stick with a cam that has 0 or negative valve overlap. The Thunder Racing 224/224 114 is a very popular cam that passes emissions and produces good power.

The equation for valve overlap is:

(intake duration + exhaust duration)/4 - lobe separation x 2= valve overlap

so a TR 224 cam is 224+224/4-114x2= -4 degrees of valve overlap.

I'm a little curious why you went with the 1.8 rockers? I know your looking at other cams, but typically a higher rocker ratio is used when someone wants to get more lift out of the valves without changing out the cam. It honestly would have been a lot cheaper to just buy a larger cam.

I guess a cam somewhere around 220/224 .550/.540 112 will be good if your using the 1.8 rockers. Personally, I'd sell the 1.8 rockers and get a 224 if you still have the stock rockers with you.

[cobrahunter]

Yeah, that's the crappy part. I had the rockers installed about 3 years ago or so. Don't have the stock rockers. Heard that CompCams has camshafts that will work well with my rockers.

TR 224. Proven over and over. 112 if no emission concerns.

i did above. i gained 9 rwhp with the rockers, and when i ditched them, i gained 39 rwhp with a 224/224 cam and dyno.

Yeah, but with the 1.8 rockers, it will make his lift well over the .600 mark.
