hey,
in the true spirit of ls1tech...
i post this question for general conversation.

what would you consider to be the perfect solid roller cam spec for the ls1 motor?
(make sense?)

all out, very rarley driven on the street type of cam.

steve frank

 

What size engine? Stock displacement LS1 or big bore?

 

Stock displacement?
Big Bore?

Anyone?

 

What would be the specs of a streetable solid roller cam for a 427 stroker that is going to be spraying???

Nitrous cams are a little out of my expertise <img src="images/icons/wink.gif" border="0"> but Nick picked the cam going into my new motor and it sounds great. Definitely not streetable. With that size engine I assume you can get by with a lot of duration and lift and be fairly streetable. Give Nick @ ARE a call and I know he will lead you in the right direction. I'd assume you'd probably be looking at something like 248 252 .622 .630 or so. Not sure about the lobe seperation but I'm just guessing. That wouldn't be super agressive in a big motor <img src="images/icons/wink.gif" border="0"> <img src="images/icons/confused.gif" border="0"> Sorry I couldn't be more helpful at least this is a ttt for you.

 

lets do this again...i think i confused what i was wanting to say.

if "you" wanted a solid roller, what grind would you get. wether the motor was a stock displacement or stroked/bored..

what im trying to do is get a general conversation started here on solid roller cams.

also, ive heard in the past that on some hyd roller cam cores a solid roller lifter can be used, but you would need to tighten the lash a bit...any one know about this?

The actual lobes themselves are pretty important with the solid lobes, since a peak lift at duration at .050 lift isnt as descriptive. You have alot more flexibility to do things more radically.

When I was looking into it, there were alot less choices. I ended up choosing with Katech a 244/244 .61x/.61x 110 ls cam that they really liked for drivability. Sounds radical to the hydraulic camp, but it was a really nice idle and was very streetable. No idea about emmisions tho.

Seemed like 250-270 duration was being used by a shop or two. Need to run more duration for mechanical to be even with a hydraulic.

 

Steve, the arm is in....

Got to pick it up tonight from ups... <img src="images/icons/smile.gif" border="0"> <img src="images/icons/smile.gif" border="0"> <img src="images/icons/smile.gif" border="0"> <img src="images/icons/smile.gif" border="0"> <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" /> <img src="images/icons/smile.gif" border="0"> )

<img src="images/icons/shocked.gif" border="0"> damn that is huge for a LS1

is that stock displacement?

actually aaron, those numbers are typical of the soid rollers i have seen.

i was thinking of something in the 245-255 range at about 600 to 650 lift for a stock cube motor.

what do you guys think?

AAron, a solid roller setup can handle a much larger spec cam due to less limitations in the lifters and such.

i thought it would be over kill but i am always eager to learn about my car <img src="images/icons/smile.gif" border="0">


oh and wazzzzup Steve?

 

We need answers here? Where are the big wig's when ya need them????

 

Steve, bigger than that has been run.

The 302ci/Westech/GM showcar runs a 25_/25_ cam.

I'd look at 26_/27_ IMHO.

 

a little TTT for ya
