400/450 stroker....Cheap parts, lotta work.

440 Source helped out in another fashion the other day.

I think this crank has had a few rough winters. Look at this crank snout........knurled.

The knurling is one of the reasons I picked it out of the crank pile, you know, use up the cheap stuff. Is it now too big? Too small?

Well 440 Source has these harmonic dampers I've used a few times and liked.....

I like them because they are sometimes pretty tight fitting and you can hone the tight ones to size. This crank snout turned out to be 1.5295, and the dampers I've received before were 1.527.

Whoa, .0025" press fit! That would have to go on and off using heat, dynamite and tire tools. Well now I can hone it out to the .0005"-.001" press fit I prefer and the damper will slip right on like it should.

Try to be smarter than your damper! Measure your crank and the aftermarket damper you are going to use before you try to beat it into submission.
