'67 El Camino H/SA

I think you should do some more checking first. Agreed that you can utilize more timing at the beginning of the run, but I've never seen anything like your combo have that much timing. Something is amiss.

X2 that is a pile of timing

Agreed it is a lot, but it will be pulling most of that out before the 60' lights easily. Talked to some racers at the SportsNationals and they were also running near that much timing initially at the start...difference was they were using micro-switches on their shifter to activate the retards.

My thoughts are the engine will never drop below 5000rpm again after the launch...it will only be utilizing the high timing for a very brief period of time. Testing will tell the tale.

Reminds me of the dual point distributor mods that permitted turning off the one set of points, so as to retard the timing.

But, if an engine makes the most power with say, 35*; how could it run better with 50*?
Especially if the stall speed is what? 5000? 5500? I mean maybe it will make more torque at low rpm's, maybe. But it never spends time there and the convertor won't allow it to.

Just thinking out loud. I had this idea for a car years ago. (Over advancing.) We never tried it because we "bench raced" past it. (And had another beer, but thats another story.)

All I can report at this time is the effect it had at the last outing. Weather permitting I will be taking it to Bowling Green this Saturday afternoon and the et slip will determine what it wants.

If your SBC likes 50 degrees of timing, it will be the first one .....are you sure TDC is correct ?......

Yeah, TDC is correct. Those racers I mentioned earlier run Stockers .900 under and quicker...they showed me the graphs of the runs, the switches in the shifter and the qualifying sheets tell no lies.
