950 rpm is way too high for a stock cammed 70 340
Turn the initial to 16*, limit mechanical and it may even get rid of your bog. See if it starts hot at 16* and I bet you it's a bunch snappier at idle. Don't drive it with 16* initial until you limit the mechanical advance
Learn what it takes to limit mechanical advance. Otherwise you will be hamstrung with a crappy running car at idle and low rpm due to the emission requirements these cars were built with.
Most of what I read says 15-18 initial, but then I've read some other info that says not to go that high and keep it around 12 with my cam so I'm not sure what is best.
The engine is a 340 with 10.5:1 compression and the cam has 114 centerline. I'll be running 93 octane pump gas, Autolite 65 spark plugs and have brown springs in the vacuum diaphragms. Should I still go for the initial of 16? I have a limiter plate that will allow me to limit it to initial plus up to 18 more degrees.
