Thanks HRL! I'm not trying to build a race truck, just one with a little more get up and go than it had before this engine went south. I don't want to get rid of the 327 because EVERYONE has a 350 these days. I like having something different.
I was afraid the 11:1 was unreasonable, that's why I was asking specific questions and disclosing what I have and what my usage was. As usual, your insight and experience is greatly appreciated.
