Project Bad Penny - more changes because done is boring

[chevyhector]

Steve, Bad Penny is one BAD ASS Camaro. We were there just drooling over the awesome work you have done ! we were speechless when Mary took the driver’s seat, in Bad Penny and her 2nd Gen Camaro !



Hey Steve, I also wanted to thank you again for the article in Camaro Performers, I just got that issue ! I also purchased several copies for the family.

Everyone, check out page 16. My Medusa made the mag. Both my son and myself are so excited !

Been having starting problems with the new engine and getting "cam sensor" error code

Worked with Scott Brown today on it and foumd that the connector was worn an not giving a cam position signal (so the computer just guesses)

Fixed that and was still getting a code... but it started more often

My LS2 is an early using an E40 computer.. as such its a 24x deal. When we built the 454 Comp accidentally sent us a newer single bolt cam. To get around this we used an LS3 cover and gear. I was focused on the 24x part that we didnt think of the 1x versus 4x cam sprocket deal.

Now mu com is looking for one pulse and getting 4.. So from a cam sensor perspective the computer is seeing 4000 rpm when the engine is ideling at 1000 rpm ... luckily the rev limiter and most functions read off of the crank sensor.. still, we think its hurting performance somehow. Just not sure how.

So, will the 1x cam srpocket even bolt to the single bolt cam? Can we "make" it work? I need to grab some parts and find out

The best fix would be to program the computer to recognize the 4x sprocket in the car.. dont know if that is possible.

Anyways, mystery solved an lesson learned.. make sure ALL of your parts match up.. lo

It would be my luck to have changed an engine and then have computer problems but for you it seems the parts just don't seem to be in your favor from the factory. What's a guy to do ?


I would try the computer and change the signal in the ecu if you can, that way we all know it can be done and save a bunch of parts changing.

Hope you get it sorted out and all is good. It sure sounds good but if it don't start, I know how you feel.

It starts.. just not every time.. 50% chance?

and it runs great once started.. Scott thinks it might be leaving performance on the table though...

NEW RULES

You have to shut your car off and restart it at the beginning of all autox runs, That way we can all have a 50/50 chance at beating you.

Its funny Steve, I had the same issue with my Mustang. I knew about the 4X vs. 1X reluctor wheels. I didn't know that if you change from LS1 to LS2/3/7/9 cam sensor, you must reverse the ground and the feed wires, or as you know, the car will try to start 180 out 50% of the time. Its funny how many bugs you have to work out of this stuff, serves us right for mismatching so much crap. Ron

I don't believe that there is such a thing as a single bolt, 1X cam gear.

Me either.. but the three bolt 1x gear fits on the 1-bolt cam, at least so far.

Is this back on the road? I assume no updates since your busy driving the snot out of it......

[Matt@BOS]

Last I heard he said it was over at Global West getting some Penskes put on. Maybe Steve will even chime in with some pictures.

[gEtyOpAPiOn]

how about machining the cam for a 3 bolt setup ? and the pin

As stated she's at Global West for some measuring and mapping.. most of involves getting Penske to come up with a custom double adjustable shock.

I've always been fighting shock issues in regards to travel even though I have plenty of room (or at least "enough" room) -- After talking with Doug I decided to just be done with it and buy the best. Doug Nordin at GW is also going to work with me and David Pozzi to do more suspension optimization. There are some adjustments we've never even messed with.

Goal is to have her ready for the LS Fest and RTTH6 events and then optima.. with a few more events when we can fit them in, but those are the main ones.

Decided to just live with the 454 issue for now and I will be starting the 460 build very soon. Swap set for late August.

I don't think that can be done.. I could just ask COMP to make me the same cam in a 3-bolt deal but at this point it's easier to just hold out until the swap.

[Steve1968LS2]

World's most expensive pile of bolts.. ok.. maybe not, but it sure felt like it when I paid for them. lol

$34 each

You've got it bad Steve.

[Steve1968LS2]

You've got it bad Steve.

Aint that the truth..

Hey, see your special section in the new issue of CP???

and you thought I was kiddin...

Thanks for the compliments.

[Steve1968LS2]

Well, this should be fun...

[David Pozzi]

Steve, it looks like you could bolt the ls2 sprocket to the single bolt cam. I'd check if the index pin is in the same position on both cams though. The most that might need done is to bore the center hole a little larger if the bolt won't fit.

The index pin hole in the single bolt sprocket is a bit bigger.. not sure if it's in the right place.

The RIGHT way to fix is to swap the cam... but we could most likely make the other sprocket work. I will send you a few to mess with.
