Re: Timing Curve Setup on my 347
I would think your 12 degrees initial timing is a tad low. I know my 347 likes about 18-20 degrees initial with 34 degrees total. I had to take the vacuum hose off my port of the dizzy/plug the hose and bring the rpms to 3600rpms/34 degrees where I locked down the dizzy. I have 11:1 compression so anything less can be pushed to 35-36 degrees or so.
Running with vacuum advance like I am.....enables better throttle response and a little bit better on the gas consumption.
I'm running a 240/246 @ .050 with .540/.544 lift on my flat tappet hydraulic.
347 Stroker, 10.6:1, Vic Jr, World Jr. heads (2.02/1.60 valves), Custom 780cfm ProSystems 4150 Double Pumper, XE284H cam, MSD E-Curve, 4.30 gears/31 Spline axles, Tremec TKO 5 Speed w/.83 5th gear ratio.
