The stock 302 ratio is about as low as I'd like to go in a high-rpm racing engine....I have run such ratios into the 7500 rpm range with no ill effects but I share the other poster's concerns about thrust side-loading on the pistons and bore...
I've always built within the 1.7 to 1.8 range, due to parts/budgetary constraints and have gotten good perfomance and service life from such combinations.
As I believe Hal said, on a street engine of modest HP, it isn't that big a factor...
