Attention 416 owners....

[2004exrider]

Im going to be building my 400 into a 416 soon. Im putting in a wiseco 11:1 piston, XR gaskets, and the other mods in my sig. My question is are any of you running a sparks timing key in them? I know that they say not to do it but are you having any problems with detonation or overheating. I still want to run no higher than 93 octane. Thanks for any help.

if your not going to run anything higher than 93 than you WILL have problems. i recommend running about 105?

I tried it with a Ross 10.8 and XR gaskets, serious pinging:ermm:
I've heard it will work with higher octane fuel.
