billet10 mil or reg 10 mil crank


Recommended Posts

I asked the same question when I was building my motor. Here's the answer I got. If you're straight up dragging, then go with the billet. The billet is a little less weight, and you can get tighter tolerances with them. Again, that's what I was told by one of the full-time drag racers on here. I got a smoking deal on a billet crank that was brand new, so I couldn't pass on it. Otherwise I would've got a cast crank.

That's pretty much accurate. :thumbsup:

One thing I would research that I have noticed people complaining about is the flywheel getting seized to the billets. I do not run a billet and have no experience w/this problem, but have seen others w/this issue. Some are lapping the crank before installing....you might do some searching and asking around.
