well i got the spark arms in the mail and installed on the car. im making a set of custom wires for them while i finish up the fuel system and wiring on my 5.0 and then i can give a driving impression of them. they clear mac equal length headers, so i know they will clear any other 5.0 header, as mine are the tightest fitting ive found. i ohmed them out and there is minimal resistance... about .3 ohms which is neglible when you look at the 40-50 ohms per wire on a good set of msd wires. i ohmed some fms wires and they were in the 1000s and 2000s. i couldnt believe it. these raise the wire connection point about 1.5-2" (or more if you adjust them differently). that is well away from header heat and probably a better, though more expensive, option opposed to running them under the headers. changing plugs isnt anymore complicated, they go on and come off easy. i will bring more reviews when i drive the car soon. i have several pics for anyone interested.
