Have you done a leakdown and/or compression test on this engine yet? It may be just too big of a cam for the static compression ratio.

I did a couple compression tests.......seems fine there.....pretty consistent across all cylinders...two were a little higher....as I recall I was up around 150-160 warm. As far as leakdown, all I did was let the comoression gauge sit and watch the needle for 30 sec or so...didnt see any drop....not sure if thats the right way though...
for gear try a minimum of 3.73.
If you had a manual trans you could get away with less but you don't.
BTW not having enough gear for a given converter will cause the trans to have 'heat' issues, at least with most cause chances are you'll be slipping all over town till you get on the freeway. You wanna try and get your cruise rpm into the converters lock up band, if that makes to you, by lowering or numerically raising the gear ratio.
Ramcharger: You got it bass-ackwards! Turn the tire one revolution. Count the number of turns the driveshaft makes. 2 3/4 turns of the driveshaft equals 2.76. This works for a sure-grip or spool.
Ok, now you are scaring me a bit.
I havent noticed any slipping or anything.....pulls out ok from lights etc....feels pretty "normal" to me......shifts real firm, etc....
The tranny was rebuilt by a shop, and I had them put in a transgo kit, billet rear servo, some other stuff.....
I have had to mess with the kickdown just a bit...setting it all the way back makes her shift late......so I backed off the Lokar kickdown cable a bit and she "seems" to shift ok....sometimes I have to back off the gas just a might to get her to make the upshift to 3rd.....but I figured that was more kickdown adjustment needed?
Every once in a while I will notice a short delay in shifting from neutral into drive.....but I assumed that was me jumping the gun a bit....
Should I be worried here????
My cruise rpm at 60.....dang it, I had made a note of that somewhere....I think its around 2300 rpm or so? Doesnt seem too high or anything....but if the stock convertor lockup is 1400 or so then I am out of that range for sure....
Shadango: Sounds like you need more "in person" opinions. Maybe put a shout-out to members in the Pittsburgh area?
It does sound like a cam, timing, convertor, gear ratio thing. A big cam could also be opening the power valve sporadically at idle, and the carb may need idle circuit changes, at the least.
That vacuum reading also could be a dead cylinder.

Lol! Yep you're right! :-D
