Me two and you might check your rotor phasing at the offending rpm EDIT since you are tracking down a miss rather than just needing that spec, more details on what you have, when did it start, what's been changed what rpm, under load or no load. I'd stay on the ign. plugs/wires/timing/rotor phasing

Thanks, I am hunting trying to find a miss and gonna check that then move over to the carb.
You try pulling a wire off each plug, one at a time...see if you have a weak cylinder, bad plug, etc as well ?

It starts just off idle, more of a stumble then a costant miss, changed the plugs which looked fine, the wires, rotor, the cap looks fine so left it alone. It is a late 360 with an early timing cover so have to set timing kinda by ear. The carb has/had those clear site plugs, on the primary it was weeping fuel. Turns out half of the threaded part was gone so took the bowl and metering block out, could not find the missing piece in the jets or the fuel I drained. Put back together and here I am gonna check the distributor, I do have a 408 on the stand so I can borrow the distributor off that and carb too. Love working in this heat too. Thanks for the help suggestions having a extra set of ears helps.

I've got a feeler gauge if you need it  (Even have a spare 750dp  ) And at least it is cooler today...I was working on the car earlier and didn't even need the a/c on in the garage

The gap can be bigger then the .008 listed. When the gap is too big the timing will jump around as you view the marks with your timing light. I have seen many where loose timing chain etc was suspected but tighten that gap up and bingo--steady as a rock!

I got a few extra things from the fastback sitting, not sure on the feeler guage though or the A/C in the garage. Next thing you know you will have a cooler with beer in yours.
Beer and Dr.Pepper in the garage fridge actually
Makes it nicer building cars

I'm impressed!
Reminds me of using a match book cover (approx. 018") to set the points in an emergency. Yeah, I'm that old.

Hey Oz thank you for the offer I have brass feelers that start at .006. Will let you know about the carb. First I gotta get a new green bearing since I messed one up on the car, always had a habit when changing gears to rap on the axles to seat them, never had greens before so when I swapped gears out sunday I did my thing and messed one up. Guess I will shout out to Dr Diff.
