Coil packs plugged in correctly?

 

Doesn't have to slip, the factory style will separate.
Drop the pan and check it.

 

Seen it on that era of Callies cranks. I like to tack weld them to the crank and the tig all the spot welds on the stock one, or any of the aftermarket 2 piece wheels. Is it a 24x?

 

coils are plugged in correctly. It's a 24x. I'll drop the pan tomorrow and check. thanks.

 

From previous posts, do a system log and you can view how the trigger wheel is being read. It should show if there are any problems.

 

I had my 24x split into 2 pieces and slip and retard the timing by 20* it would still start and run but was way down on power.

 

Yes it slipped. I had the same issue with my Callies 24x crank. Sent it back to Callies, I bitched up a storm and they agreed to install a new billet one, then had it tigged on. No more issues.

 

it moved. mine did the same earlier this year. drop the starter and pull the crank sensor out. bet you can move it with a screwdriver. i put a billet one piece one and welded the bitch on

 

LME makes a nice 24x billet wheel

 

They sure do, but get someone who knows what they are doing install it.

 

Yep seen it happen twice. We use a billet and tig it if it's going to make good power.

 

They are not rivets. They are actually stamped together. Welding has to be done on the backside to attach the two pieces together. I do every build like this to avoid problems.

I've had this problem with Callies stuff more than a handful of times. Its not even worth the phone call anymore. Every crank I use gets the stock 24x wheel tigged together and then tigged to the crank. They are machining to much off the back of the cranks and the reluctor doesn't have a full pad to ride on. Which splits it or makes it come off at high RPM.

 

When I had my 2nd engine built. I had billy Briggs weld the billet wheel to the crank to avoid this exact problem.

 

Did you or Billy check the run out on the wheel after it was welded? If so, do you recall what it was?

 

Is this more of an issue with Callies cranks or all cranks?

 

That would be a question for billy

 

I always keep runout to less than 0.020. And Ive only seen the issue with Callies cranks, but all cranks get welded now.

 

The CBM billet wheel is a nice piece

 

Yep, took the engine apart , reluctor wheel in 2 pieces! Anyone run a 58x with 1x cam with holley efi? Was thinking of putting a 58x wheel on.

 

No reason you cannot use a 58x and 1x cam, and it is a much better trigger wheel anyway.

 

^^^^This^^^^

 

At what hp level does this become an issue?

 

I had this happen at 500 HP NA in 2002.

 

Comforting lol

 

After all the problems with the 24x stuff if using a aftermarket ecu why not use a 58x

Tim

 

58 will do it too. Weld both

 

can you weld the wheel while the crank is still assembled in the short block? Will this affect the balance of the rotating assembly?
I have a Callies crank in my Ls7 shortblock that has not been put in the car yet. Should I weld it or let it ride and see what happens. I don't want to pull it apart to weld it.
