Alky Plugs?

I have converted to Alky. The plugs I was running with gas are NGK R5671A-9. What do yopu guys run in the alky setup?


Thanks

Lol you've been in the desert too long. That camel nookie is affecting you.    

You should be able to run the same spark plug you have.

Yes, please tell us more.

a lot of people run a gap about .025 on gas and for what we have seen on alky the best is around .035 its faster than .025 in my truck and our other motor

For the benifit of others....what plug are you running and which 'box' and coil do you have? Also, how much quicker?

auto-lite AR-34 I think is the plug number. MSD 7AL3. MSD pro coil . and at least .050 quicker

I was told just the opposite, close the gap with alky, to about 25, about 50 with gas, with msd box and coil.

idk I just know the results on my truck and I have tried them right out of box make a pass then gap them and will run quicker but I guess every app is different

Would that be a AR-3934?

Gas or alcohol, gap shouldn't change much, gap is a result of the amperage/voltage of the ignition system, and the resistance to the arc by the amount of stuff you try to squeeze between the two electrodes. More compression, less gap.... at 18-1 it likes to blow the spark out at anything over .026" with a MSD7al3 and a pro-power coil.

It's ...close the gap if you have a mag. ...050" with gas is waay wide i.m.o.

Aint nothing perfect....run what works  

On my AR34"s I don't touch them,just screw them in after a quick peak. 

i run NGK -8 or -9 from .020 to .030 with no problems. 7al2/propower .......... 

I got a 7531 drivin an 8 plus box, im gonna crank up the gap this sat and see if we can get into the 5.0x's...........;-)
