340 Initial timing questions

AJ, I can tell you have a sweetly dialed in combo, and sense that you have a lot of fun driving. Always enjoy your imput.

I had been setting idle to about 750-800, but due to "something I read", about somebody feeling their cam oiled better at 1000.... anyway, I was just experimenting with setting it higher. Moved it back down some this afternoon.

This whole T-slot thing, I assume to be related to Holley style carbs? I am running an Edelbrock 650AVS2. Still tweaking rods after getting the jetting real close. A/F meter helps me keep an eye on things. I certainly do not have any hesitation off idle, or at any rpm when I mash the pedal. I have no hesitation whatever at any speed. It's right there when I want it.

Yes, I'm running an automatic (518) and 4.10 gears but with O.D. and 11" lock-up converter with a stall of 2500. This cam actually pulls pretty good from 2000 up, so works fine with the 2500 stall (which is what Lunati recommends anyway.)
PTC did the converter for me, and I had them do a freshen up when I had it out. I can cruise comfortably at 85mph or whatever semi legal speed on the interstate, and still run the 4.10's for fun in town.
