Box Stock

BOX STOCK 212CC HEMI PREDATOR DYNO NUMBERS?

Some of the stock springs are right on the money with a legal clone 10/8 spring and then there are others that are of the type I would use in a small plate engine
 
Good information. I will try to do some dyno testing as well at a local shop when I build my next stock predator.
 
Digging on an old thread here....but if anyone plans to do some testing would you be able to run hemi vs. non-hemi. I know people crave the hemi for the stock predator class but would like to see data showing one better over the other.
Unless it's posted somewhere else lol. 🤷‍♂️
 
I have a non hemi on the dyno now but had to take the carb off because it wasn't working correctly. I will post when I get it fixed.
 
Well, not a good morning on the dyno with the non hemi. I played with it from 9 to 11 before giving up because I had a purple plate clone to get ready for a friend. I just couldn't get it to turn any rpm without surging and it took forever to rev back up. I even put another carb on and still had the problem. When I get back to it I will post.

I had the same issue before. My spark plug wire came loose from the holder and it was rubbing the throttle lever
