224/230 on a 115 .581/.588 good cam. Slight chop at idle. I went with a 226/232 116LSA for my new motor(little more chop ). The Thunder racing blower cam 214-230 601/575 lift on a 117 +1 will idle like stock.. The Comp 214-224 585/563 lift camshaft on a 116 + 4 degrees with EX intake and XER exhaust lobes will also idle like stock and be easier on the valve springs..All will make great power...

Lawn, yoiu keep posting about that Thunder RAcing 214/230 cam, why don't you do it and then let us know how it goes. I think you are splitting hairs by posting this question every couple of weeks. I'd like to hear this cam actually.

I am going to find out how to save a sound file of my Ute running a 224/218 @ 114 lsa .527 lift + 1.8/1 Rockers

I love the sound of this one combined with the sound of the F1 Procharger, it's almost frightning,, without being too much inya face, if you know what I mean.

As always, I run out of time before racing. I read that much crap around the net, and spoke to different people, and after my initial impressions of the GT2-3 in my car just didnt impress me enough ( but I am talking only, 3-4days usage, and minimal tuning time spent, which was stupid of me )

So it got me paranoid, that I needed a bigger cam. With me going to race in about 2 weeks....I ordered a cam ( bare in mind Im in the UK, and sourcing parts isnt a next day affair ) from Thunder. Not what some would say is an ideal blower cam, but I went with it nonetheless. 230/236 on 112. ( Ausie guy actually reccomended me a bigger
It idled horribly ( although some would love it ) and did seem to perform ok. Best I managed with that cam was 11.17 @ 136mph on pump fuel. No idea of power though.
With hindsight...as to how the car felt on the road power wise...I dont think the bigger cam really did perform noticebly better than the GT2-3 could have. But I really didnt spend enough time tuning the GT2-3. I just gave up after initial impressions werent good enough. I spent as many hours/days as I could with the 230/236 before I went racing. Similarly, initially it was crap, ecept I persevered..

I firmly beleive if I had spent similar time with the GT2-3, I would have got excellent results, with much better driveability and road manners.

Im now on a 382, and I opted for a 224/230 on 115+4.
So far, my current setup has far exceeded all goals I had hoped for, and it idles nicely at 800rpm. I think its great....the only thing the grinder didnt give me, was the 0.600 lift I wanted. Not sure why....although I didnt order the cam directly from them, I relied on teh guy supplying me some other parts to do that. ( I basically wanted an FM7 on 115 as opposed to 114, in a hope to soften it a little in terms of idle )
I'll address the lift issue with rockers soon though.

So, I am happy with my current cam choice at the minute.

Am I tempted by a bigger cam ?? unfortunately, yes I am...but its too much time money and hassle for me to do it.....on the same note....perhaps a smaller cam might work better ?? maybe a tigher LSA ?? Who knows.
Far too many cam choices out there, with no real back to back testing thats easily accessable.

If I want to race to test, or get to a dyno to test it...I have to travel to England, which would cost circa $1000 or so plus a couple of days off work.

So that just isnt going to happen.

Thank you Stevieturbo

and YES to you Pro STock John
I think i am going to scoop up the thunder Racing 224-230 blower cam for my build up.

But i wish i knew of someone local who is using it,
Or anyone on the LS1tech board.
I would like to here it idle and perform first , but by talking the Thunder Tech guy Shawn, he filled me in on why the cam is on a 214-230 117 +1 lobe ,and how well it will make things work with a procharger 346 LS1 .

It is suspose to idle nice and pull to 6,500 , with good bottom end;.
I do trust Geoff at Thunder (cam desinger) , Thunder Racing has always had good cams, and there tech guys know there stuff.

Can someone post the link to the camshaft sound clip link.
Thank you

dude pull the trigger already. Thunder is telling you its a good cam, we're telling you its a good cam. how much reassurance do you want?

screw how it sounds, it'll sound good enough.

get the cam already!

I dont have the ***** to go lower than a 114 LSA. I enjoy the way rides on a nice nite and sometimes I can feel a little shake here and there at a traffic light. Hell I might even go 115 or 116.

The stock LS1-LS6 cams are all on 116-117 LSA's

this is for good idle quality

And to all the rest of you, Thank you very much for your help,

I Just like to realy research befor i jump into anything , and with all this camshaft voodo and how everyone can tell you something different and all the choises out there, it didnt hurt to reasearch and find out .

I would still like to know that cam sound link , i went on it a year ago , it was pretty cool

Tonner

Id like to hear it when you fit it.

Is there any advance ground into this cam?

Was that a reply to me?
If so Slowhawk stated the cam is a 115LSA not 117
