He came back at $125 plus shipping, so I took it. I'm not going to let a few bucks keep me out of budget go-fast part lol.
that gear should be the brownish colored gear for 373,So the new speedo gear is already acting up. I've literally driven it to work twice. Is the only way to really fix it to pull the tail shaft and replace the gear inside there with a 6-tooth?
I did notice what I thought might be some pinging - but I can't tell for sure. It doesn't do it during acceleration, but say I do a solid mid-range pull, let off, and then get back in it I hear just a couple or three what sound like pings. It immediately clears up, but I want to make sure I'm not getting detonation. Is there a solid way to tell other than just listening?
yea its already into the hot season there, not sure I would play with it.What octane gas were you running? I'm about to start my engine for the first time. I was planning on setting it at 10* for break in and then bump it up to 12*-14* once break in oil is out and there a few miles on it. My 331 has the comp ratio bumped up to 10.3 I'm kind of worried about pinging in the desert here in PHX. We only have 91 octane.

Agreed, I am probably gonna run 10* in the summer and only drive it early mornings on weekends and bump it up in the winter time just to be safe. Not sure how its gonna like 91 octane with 10.3 CR when its 115+ outside, even with aluminum top end, radiator and 160 deg t-stat.yea its already into the hot season there, not sure I would play with it.
This will be the route I take if my bracket making ends in failure. Thank you for the idea!Just go to the junkyard and get another passenger side track and use it on the drivers side.
