1.5 or 1.6 ratio how to choose?

Andy, you're a true asset to the site. Thanks for that very informative article!
Thanks. That was back in the days when I had a cushy side gig writing for Motor Trend. They would pay me $1500 for the article and the vendors would send me the parts at a discount or sometimes for free. I had to do all the labor and pay for the dyno time, but I usually broke even once I cashed the check from Motor Trend and sold a few of the used parts. So it wasn't really a job, more like a hobby that paid for itself.
