B/RB height in A body
on my 72 big block
I have a set of fender well headers, I started to cut up to fit better
but,I went with
max wedge manifolds, swapped sides,
they will exit the rear, over the axle, to the bumper.
3">540ci
did have to relocate the master cylinder and alternator
but was better than moving the firewall,heater motor and steering column.
plus doesn't cook the starter, easy to remove if needed
