[69mychevy]

hey i've got a 69 chevy 1/2 ton stepside with flopro mufflers and chrome tips out the back i wanna make flames come out the back and i've got a few questions before i do it. 1 where should i get power? the plug wires??? 2 what kind of switch should i use?? ( i don't want it on all the time obvioiusly) 3 how far back in the exhaust should i place the spark plugs and should i just use 1 per pipe?? 4 are there any precautions i should take so i don't blow up my mufflers??
thanx for ur help
