So I have small chamber W5's, 53 cc's, a pretty tight quench at .031 and about 12.7 compression. I ran my old 360 at 34* and never screwed with it. I guess what I'm wondering is with the increased piston speed of the stroker I probably don't need as much advance. I had it set at 34 initially and I just knocked it back to 30 and it sounds better just running in the garage.

I know I need to experiment but I can't get out to the track now until November. I was going to go today but there is a storm system to the south of us that is just wreaking havoc on the weather. So what have you all found your car likes?

i had w5's on a 416 shortblock about 11.5 compression with a 260/266 flat tappet that through trial and error found it was fastest with 40 degrees of timing...turn it back and the car fell off,..was a tenth slower with 34/36 degrees in it on back to back laps.

fast forward, same heads on a new 13.3 roller 422 shortblock, car ran best at 32 degrees, i could put 28 in it and that killed a tenth....so, it depends...
