cam swap for next month
I heated my crank pulley to 200 degrees in the oven for 40 minutes. Rubber harmonics inside of it never melted of even got tacky. Then i banged it on with a 2x4 and hammer probably 7/8 of the way and used the bolt the rest of the way. Runs fine for me. I'm sure if i heated it to 250-300 it would have gone on all the way. It doesnt require that much force to bang on when warm, and i highly doubt it's going to get distorted at those temperatures as im sure it sees around 200 being in contact with the crank as it is.

I've only done 5 LS1 cam swaps thus far, but I've never experienced the problems with the harmonic balancer that seem to be described by others. I use a cheap (AUD$30) 3-jaw pulley puller and a longer bolt with a large washer to get the balancer back on - works every time.
