so I got my car back last fall from having a whole new drive train put in it. the motor is a 383 with TrickFlo heads, HSR, and cam with the following specs: 520 intake 532 exhaust with a 112 centerline 224 intake duration and 235 exhaust duration. my question is, how aggressive is this cam for a street car? it idles a littles ok, but it is a fast idle. I am about to begin tuning and just curious for thoughts on what I am in for when tuning the idle. thanks.

 

I assume thats a hydraulic roller cam? Who makes that cam, i havent seen anything with thsoe specs?

Either way its not a really aggressive cam for a 383 HSS car. I'd say its a good street strip cam. the motor i'm building will be using a bigger stick than that with lots more overlap and i'm thinking i could be in for some long tuning sessions with this setup Gonna be rough to get it all down but i think its doable.
Your cam should work out well. Its very tuneable. Thing is tho i have MAF system and you have speed density right? That could be abit more challenging as i dont know much about SD. It is more finicky but its possible to run that cam just fine. Many ppl have done similar cams before.

 

thats what I was hoping to hear. cams are still a "black voodoo" thing to me. that is sad as the EFI tuning thing seems to make a lot of sense. I am learning but I just wasn't sure how aggressive it really was. sounds good though hahahahaha

 

yeah the more you learn about the tuning part the less aggressive cams get to you you'll beablel to tune bigger and badder setups to a point the ecm cant handle it anymore..... i'm just somewhat beginning myself. I've played with bolt on L98's and now i'm jumping to a cammed 383 so we'll see how it goes. I got an idea what to do from reading the threads in DIY Prom, so i suggest you go there to get an idea whats goin on

 

Curtis, its not that bad. A LT4 hotcam is 218/228, so its not that much larger or aggressive considering you are on a 383. The HSR should like that cam.

 

Doesn't seem too particularly aggressive..... it's about like a Comp XR276, except with 1.6 rockers, and the computer-compatible nitrous version of it. See this cam right here.

Shouldn't be too terribly difficult to tune, I wouldn't think.

I see you're from Crete.... I actually have family there, if they haven't all moved away. Haven't heard from any of em for a couple of years. Pretty small world, eh??

 

Did you live in illinois, or just family?

 

I did, at one time.... AFAIK a few family members still live around there.

 

well I am glad this is all good news. didn't want to chicken out
