Thanks

Thx @whitmore! However, question 1) and 3) remain. Can anyone shed some light on this?

The pic and drawing aren't the same plate. The picture is of a #4 plate which is the most aggressive out there outside of #0. PDR Cam plate HP guide.

Nate, not trying to argue, but how is a #4 plate more aggressive than a 100? because it fuels more in/out of shifts when it comes to having an auto? or what? Explaination would be grand!

I'll say I haven't seen too many commercial plates, however, the pictured plate would be more aggressive than a 100 plate and here's why. Generally when folks make their "100", they grind the main face even with the face of the top plate, just like a "0", but then hook the bottom. The hook on the bottom is what gives it it's hybrid state bewteen a "0" and a "10"...hence "100". The pictured plate clearly is cut deeper than that. So much so, that there isn't much material left around the rivets. Don't let the the shallower portion above that fool you though, as it never sees the gov arm. This plate really doesn't defuel much once off idle. Gov arm travel is usually no more than 3/8 to 7/16 up the plate from point of contact. This also makes adjustment of the plate and gov arm crucial so as not to underdive the plate nose.

Sorry Archer I couldn't answer #3 for ya, but I tried #1.

Chris

QUESTION: if ya grind a stock plate into a 100 how far fowaard is a safe ? and what are the dimensions of the hook on the bottom? or is it just a good guess, currently i have my stock plate full foward, oh and will you have to reset your govenor arm as well???? plan on doing it as soon as this hurricane passes
