Crank scrapers or plate...?

For one, to work, they need to be hand fitted. Are you going to pay for that in an OEM deal that don't need it?

Stroke length is a big factor.

Oil wraps around a crank like a blanket. Any time you can lose it you are better off.

Call IJ and talk to Kevin. He will explain to you how wrong you are.

Oh wait, I forgot...he has a vested interest in something he sells.

I can see this is going to go the way of the adjustable PCV valve. I bought one and caught hell for it. Luckily, many guys are using them besides me with much success.

The crank scrapers is no different. If you are bother isn't to spend the time to build an engine, why not spend a few extra dollars for a crank scraper.

Unreal.

Very true........

So we made a crank scraper and windage tray for the 357/340 in 1977. Made a few dyno runs, 595 HP. Dropped the pan and installed the scraper and windage tray, 610 HP. It was enough of a difference that Cale Yarborough was really pissed that he couldn't catch the 'ol #93 Dodge going down the back straight on the road course at Riverside Raceway in California.

2009, I spent 4 days building a crank scraper for the 451 stroker. It was part of the reason we made 136 HP more than the next closest engine the same size in the contest.
