'67 El Camino H/SA

Dave Gantz · 07-26-2017, 07:22 AM

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.

No harm in trying it, if it doesn't like it what are you out one pass, and isn't trying things the name of the game in stock and superstock. I always thought that was the key to speed buy it, try it, and put it on the shelf

Results are on hold for a bit...lost first gear in the metric right at the hit on it's first pass yesterday.

The metric is still in the shop, but I have a new Coan LW TH350 along with a matching converter in the car now. I figured with the added low gear set I would'nt lose too much vs the metric. I'm looking for it to be a more durable unit in the long run.

Concerning the timing experiment - While the new parts may negate an accurate comparison for now, I cannot discern much difference in performance between the two transmissions/converters. Took it to a local bracket race last night and had a limited amount of time to experiment (did make it to round 5 tho). It is still hitting like a hammer at launch with wheels in the air...the reduction in 60' times nearly a tenth just as it showed with the metric combo.

I'm pretty well convinced the results are due to the timing alterations. Next outing I will try some subtle changes such as pulling the timing back sooner.
