273 cam suggestions

Cudaguy,
Sorry for the hijack just got a little excited. You got a great running 318 and I wish I knew more about your "stock" compression 273. Have you pulled the heads off the 273 and measured how far down the hole the pistons are? 120psi compression is at the service limit so if it were me I would want more with any cam.

You could zero deck the block / shave the heads a little and then you would not have regrets after the fact.

As far as cam choice, that cam you have in the 318 worked great and it should in a similar built 273 but compression will be a factor.

I am not a cam guru, just offering my opinion / advice based upon my mistakes.
