I try to keep them at 32 * I’ve went as high as 34* unrestricted and even 36* with plate engines but now keep them all right at 32*

So what number key should i use ?

 

[flattop1]

Cross the part number .
I can safely say its a 28* .
Version 1.1 and i think the new ones are marked . As 32*

 

[flattop1]

A 4*

 

[OVALTECH1]

28 degree flywheel add 4 with a key for 32

I went on ARC my flywheel says its the 6619 and this is the info on ARC 32° with stock key ? So leave it with stock key ?

 

[monsterclone]

Its the 6619 model .made in 2012 .i saw the Video on ARC they are saying these old flywheel ls are 24° the newer ones 2014 and up are 32 ° .

I couldn’t read the numbers on it. Early flywheels are 28 so add 4 the late we’re all made with 32 degrees built in

The ARC 6619/6689 model flywheels that are set at 32 degrees will be engraved with "32 degrees advanced timing" and have a date code of 2014 or newer. If it is not engraved or a pre 2014 date code it is set at 24 degrees with a stock key.

I have 4 motors with the same flywheel and I check the timing every time I remove a flywheel and put it back on and all 4 motors use a different key from straight up to an 8 deg key I recommend learn how to use a timing light and do it or you have no clue where your timing is at.
