When ya got the time, I suggest that everyone click onto rehermorrison.com. Forget that its a Chevy site, read everything on the site. Its a wealth of info. Take the time to read the tech articles. Pay paticular attention to article #17. Everyone can learn from the masters on this site. I'm a machinist with 22 yrs. of experience, I have a pretty good handle on engines in general. Their 2 engine books are invaluable to anyone who builds their own engines. My $.02 for today.
