hemi firing order

can anyone tell me what the firing order is for a kb hemi??also how many mag kill switches do i need and where should they be???..thanks....

 

1.8.4.3.6.5.7.2 counter clockwise

you need just one mag kill where you can reach it.

 

18436572 is the firing order. depends on what type of mags you are using

 

does anyone use the 4-7 swap?

 

that 4-7 swap is for the chevy
chevy and the hemi have the same firing order
but different rotations
hemi counter clockwise
chevy clockwise

 

Yes , using the 4-7 swap in our hemi .

 

just curious, what is the '4-7' swap and what benefits does it have?

 

No hard feelings or anything, but that motor seems a little too advanced for you, what are you going to be doing with it, don't want to see you hurt yourself or somebody else.

 

thank you for the replys and the confidence boost. ..yes i'm new to blown alcohol engines but the only way i got to know about anything interesting in life was by reading books and asking questions,as there seem to be no books on running blown alcohol engines i'm asking questions instead.previously i drag raced vw's and v8 vw's and information was everywhere,magazines,forums,clubs and lots of books.now with blown alcohol everything seems so serious,like people are guarding the secret to the universe.if anyone will still answer,as usual i have a question of the day.on a mag with a 3 wire plug where does the extra wire go?.i have 1 red 1 black and 1 black with white stripe.all the diagrams i have are for the basic orange/yellow 2 wire type

 

we are trying the 4-7 swap in a brad 6 this year.

 

dont expect any noticeable performance gain with the 4/7 swap. i have tested it on the dyno, however, theoretically, it does offer less torsional abuse to the crank
