I have a 2 degree advance on mine with 1010 big bore with high compression head works great. Tried a 4 degree it work good for a while but ended up shearing the key not fun.

Do any of the 900's have this key? Is the 03.5 equal to having the 2 deg. key,Or is it all in the programmed timing pattern? Does it advance higher than the ZR';s and 04's and later?

Thanks
Mike
