As an 'outsider' looking in, it seems we have a number of combatant posters who are not so much interested in learning or discussion as they are in stuffing someone in a hole for saying something they may not agree with. That doesn't seem too conducive with a learning and sharing type atmosphere, and it seems from reading other threads, many people are wondering why certain key people have gone away?
Then again, I work in a heavily science-oriented field where we're mostly interested in data and facts, and once a theory is reached, we hope someone can disprove it before we've spent too much of our own time with it.

I like lots of varying perspectives on things -keeps this hobby exciting. I'll go to the Ferrari forums if I want smarmy responses steeped in whatever preconceived notions one may have gleaned about the author.
And that's my welcome to the forums speech.

Yea i have stock wheels/tires on my car now... can't hook in 3rd gear ![Sad](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_sad.gif)
It's not like a stumble, but it makes noticeably less power with the leaner A/F. If I was going past 1.00 I would understand the diminishing returns...
On a side note, my cam is so big I cruise at ~60kpa at 2600-3000. If I give it a good bit of gas it makes 48-54kpa while accelerating at 3800-4200. Idle at 78-81kpa. It makes it difficult to get acceleration fueling dialed when vacuum RISES with more throttle![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

With the small bore and small chamber you'll be working with on the LT1, and good squish you could run 13-13.5:1 easily and safely depending on cam choice. The 14:1+ stuff just doesn't belong on the street IMO

Of course, I live in Texas and we see better than 70% humidity here for good portions of the summer, and with ethanol's affinity for water, you're octane rating is in a constant state of flux here. Not so much of an issue for my trailer-queen road race car, but something I would definitely be concerned about in a daily driver.
I'd also stay vigilant of oil condition, which you could confirm with a sample test to Blackstone easily enough. Use compliant oils. I've had to go two steps colder on the plug, with a 1.5mm gap. I'd imagine the same is going to be true of a street driver.
