I have a Pertronix Flamethrower distributor in my 383. Stealth heads with domed KB pistons (KB400). Holley 830 and Torker intake. Voodoo Cam. I finally got my timing tape on it yesterday and got to look at it quickly before it flew off! The problem I am having is that the car runs perfect set at 20 initial and about high 40's full. Everything I am reading says this is too much but if I back it down to 12-14 and about high 30's it doesn't run as good. Any ideas???

That's what I was thinking. I have to get my info out from the distributor and figure out how to change it.

if it's not pinging I don't see a problem , though hi 40's ??? When I went to the pure stock drags in 06 some very well versed guys from the detroit area told me to bump the full advance timing on my 69 383 to 42 degrees , I bumped it to 40 , car did pick up ...

what he said. FWIW timing tape is a joke. Get a good timing light w/ an advance.

Yeah the timing tape seems like a joke. I know I have read that 383's like the timing.

My 10,6:1 383, 75cc stealth heads, KB400 pistons likes 24 initial but it kick backs when fired up. So i put itat 22 initial. For safety reasons (you can have knock but ont hear it) I run at 38 total but when I was at 8,7:1 before rebuild it liked 45 total (no vacuum).
