Re: LARS Recurve Kit, any recommendations (Rick Church)
I have replied to a few of these in the past with: "The best 40 bucks I ever spent on my Vette......." I'll stand by that statement.......'Nuff said. :cheers: :cheers:

Re: LARS Recurve Kit, any recommendations (Rick Church)
Coupla of points... lars instructions try to cover it...
If you add his weights instead of keeping the stock ones you run the risk of either too far advanced when at the top of the curve or not enough advance at the bottom of the curve... those weights hammer the advance curve.
My engine can not handle the 30+ degrees centrifugal advance on pump gas here in LA.... I spent weeks trying to keep the advance super high while adding octane booster but I always got piston clatter - bummer. I gave up and decreased the full advance back down to 28-degrees for no clatter (and no haul-butt either). Keeping the big weights in there also force the idle advance way down into the low single digits. My car starts and runs ok with the low initial setting but I will eventually get out to the garage and install a milder set of weights to match my particular situation...
The real key is to find a way to keep better gas in the tank all the time (even when your out of your neighborhood) and zing that baby back up to 30+ degrees full... that way the bottom is just about perfect at perhaps 12 degrees at idle... The car runs like perfect with that combo - just not on pump gas!!!!!

Re: LARS Recurve Kit, any recommendations (Carl in LA)
Carl, can you please be more specific about which gas (octane?) you're referring to? Are you saying that 94 is not sufficient for that kind of curve? Or are you talking about the additives in the gas? We have MTBE here in winter and my shark gets really pissy when I give her that crap. :rolleyes: ~Juliet

Re: LARS Recurve Kit, any recommendations (redwingvette)
Also the best 40 bucks spent on vette. Then I went to Sears and bought an adjustable timing light too.
It is more convenient to use than non adj. type. Follow Lars instructions to letter and it's easy and it
"do" make a difference. Performance, starting, it just runs better. I found that I had to back it off
from 34 degrees a couple because of a little jerking at slow speeds in fourth. And at that it was only
at extremely slow speeds, sometimes I'm just to lazy to shift it has enough torque to take corners
in fourth and I like the sound of the chambered exaust under a load. Steve

Ha... Ha, Ha, Ha..... Haaaaa, Haa, Haaaaa, Haaaaaaaa, Haaaa (or what ever that laugh by Tom Hanks in the money pit sounded like!)
LA is down to 91 octane including MBTE
If I could get 94 on a regular basis I would be timed back up in the 30+ range. The 383 REALLY responded well to the higher advance... under 30+ makes the car feel sluggish - in comparasion (after all... it is still a hopped up Chevy small-block!)
