You guys are all missing the point here. These "built" crate motors are not built with aftermarket parts! They are REFRESHED with new bearings and valve springs so racers can have an affordable motor instead of spending $4000 dollars every off season! Just because a crate motor isn't sealed by gm doesn't mean it makes 600hp! Alll these crate motors are junk and I think wall is doing just fine with the division!
EVERY crate motor still has to be sealed by wall stadium. The cam lift, duration, compression, cubic inch, intake, etc are all checked! There isn't anything crazy you can do with how good wall checks them. The weight break is a great idea. Let the track do what they are doing. If your worried about getting beat by a "built" motor, then go play golf. Every motor is extremely close IN the crate division!
