I'm helping my cuz put a 240/240 550/550 112 cam in his M6 Z28 this weekend. How do yall think this ***** is going to idle and what should his shift pounts be. Cam sounds real big on the dur. side to me but he said we are going for it. His car is stock except a lid, cutout and spec III clutch. Any predictions???!!!!

What's the lift on the cam? What springs are you guys going to use? And I really hope he has headers... does he?

Is the 240 intake duration a bit much without flycutting? Just want to know myself.
I thought 232 was at the limit.

lift is 550/550 as of right now he is running stock manifolds

I hate to say this.. but my prediction is he'll wish he never did the cam swap. That's a shitload of duration for stock cubes and it is really going to choke on the stock manifolds...

Do you guys have someone lined up to do some serious LS1edit to the car or is he going to try to run it with the stock program?

Steve98Z

I think Ed Wright is going to do the tune, I too am worried about this cam but am trying to keep an open mind about it. With stock tuning idle should be nasty as hell at best

waste of time and money.
Minimum of LS1 edit on the dyno is necessary and that sucker is going to peak HIGH.

Also without headers and proper tuning he will likely make a lot less power than stock.

gomer i have headers and asp pulley and x pipe all on the way to go with that cam. and ed wright will be doing the tuning very soon also i am using comp 918s and i have hardened pushrods. it should be okay then i would think

Is it Yun's car?

Keep us posted, sounds interesting. Please post a graph or let us know how the midrange looks.

The headers and exhaust will make a LOAD of difference with that cam. What is the ICL of the cam? If it is a "straight up" cam, you are really going to have to spin the motor. My 231/237 112lsa has 2 degrees of advance, making it a 110icl and I shift mine at 6,700 at the track and 6500 on the street. Ed will have his work cut out for him making it daily drive good. I'm anxious to see how it turns out for you.

yes pro stock john it is my car and soon as we get every thing together i will get you a graph. and yes gomer it is straight up i think once i get the bugs worked out it will be a good set up???

I would think +4 would work better no?

Yep, advancing that bad boy 4* will bring the peak power down some.. but I would REALLY check my P/V clearance then.

That's what had me worried when I first read this.

I personally would not even try to get Ed Wright to tune that thing unless it was right in front of him. Go with someone who can put a load on it. I am flirting with the idea of a high duration cm with lower lift numbers myself. But mine is a H/C with exhaust. I see no reason to run a .600 lift cam when your flow numbers are like 306 @ .550 lift
Let us know hot it turns out.

Steve98Z

I agree PSJ, I think the cam needs to be advaced at least 4* probably 6* or more to bring some of that power down. Right now with the stock rev limiter he won't hit anywhere near his peak, with tunning he is looking at shifting at 7K with it straight up, the bottom end won't hold long....

That thing isn't going to idle... Especially with a mail order tune...

Stock heads and exhaust manifolds to boot. Let us know what the pistons and valves look like after he tries to start it for the first time...

To each his own...

i think it is insane but try it out and tell us what you find out. not long ago people told me that 230/230 on a 111 lsa wouldnt idle on a stock headed auto car. i would NOT do mail order tune, esp with so many good tuners in tx.

I used to run a solid lifter 270/270 in a 389 cube engine. I think you will need to set the idle at about 1250 rpm, and it will peak at over 7000 rpm unless you advance it a few degrees. Better order an adjustable timing set and some ARP rod bolts right now! You will likely see the need for some 4.56 rear end gears also, it's going to be pretty lazy at anything below 3000 rpm.
