Spark Plugs

[MUDBIRD65]

which brand of spark plug do most people run in their 'birds and why?
i have a 65 landau, my great uncles when new, ive installed pertronix points conversion and flame thrower coil with msd super conductor wires and accel heavy duty cap (all with summit racing) but im confused as to which plugs are best. also what is the recommended gap? i seem to remember 0.034 from my other 390 motored cars and cannot find my shop manual for the life of me.
thanks for the help.
happy motoring!!

The book says Autolite BF-42
Gap 032 -- 036

You may be able to make the gap bigger with the Flame thrower to 45. Maybe Summit or one of the other guys on the forum know for sure.

what will a bigger gap do for me?? what do ya'all think about "Champion" spark plugs
seems to me i've heard bad things...

A wider gap is supposed to give you a more efficient burn. I don't know if you need a a plug with a colder or hotter heat range Though. I have the petronix with the stock coil and the cars been running great for two years.

Always sworn by Champions! top spark plug IMHO.(but do you know AC stands for "Arthur Champion" founder of Champion??)

thanks for the info, the parts counter guy at NAPA told me the "Champion" story. i checked the Pertronix website and they say "most applications benefit from an increase of 0.005" over factory gap setting"...so im thinkin bout gap'ing mine to 0.040-0.041".
thanks for the help :cheers

alright ya'all thanks for all the help, ive got the pertronix ignitor, flame thrower coil, msd wires and champion plugs gapped to 0.040"...the thing runs awesome....especially when i jump the coil to the battery...seems there's too much resistance in that resistance wire to the coil... so i need to find a keyed 12v power source to bypass that resistance wire to the coil...

anybody been up this creek? any idears..thoughts, recommendations would be helpful im not too keen on the wiring stuff....thanks again
:cheers
