HT413
Semi Pro Bowler
How do you like the 413? If I get the 413 it will go in a Power wagon, torque is what I am looking for.
Sure, runs really strong. The guy before me (or maybe before him) put the combinaton way out of whack, but once i get it to where it needs to be with gear, converter, heads, cam and intake, I expect it to be a real torque monster and a real hoot to drive.

There are a few things you can do with it. Mine has a steel crank and pretty sure they're LY rods, so the bottom end is as stout as the best 440 from the factory. Hughes has some pistons and rings for like $450 for a set of cast flat top pistons. They'll be 0.067 in the hole but will bump that compression way up. Assuming you're going to have it torn down and rebearing, ring and hone it, the pistons seem like a no brainer.
Also, like was posted above, get some closed chamber heads and that'll boost it up almost a point. A guy on here has some race prep'd 516's ready to go. With pistons and 75cc heads, the compression will be about 9.5 with 0.040 gaskets.
Or leave it all stock and get that supercharger kit that is for sale here and have a ton of fun in that powerwagon.
However, after all that work ahead of you, you still only have a 413 so you'll never get your money back out if you decide to go another direction.
