Need a little help in advance

the LA 318 throttle bracket is mounted on the intake..the intake bolts go in on an angle...the Magnum engines bolts go in vertical...think you might have a problem there...

problem with magnum bracket has it has no provision for kickdown linkage,,,,

AR Engineering has a bunch of brackets...

but his magnum bracket use the Lokar cable for kickdown linkage...

you might be able to take the stock bracket and bend it to fit...wont cost anything...
