Anyone Running A 400 In Your A Body

This is my plan,and so far towards that goal I have a 78 400/727,shumacker mounts and a fibreglass front end. The inner fenders will go,but the shock mounts will stay. A tube frame arrangement will replace the inner fenders.Should help make way for bigger headers.

I've been looking at a front mount rack and pinion arrangement to further clear the route for headers.Seems to me the biggest barrier to making big power in a big block A is the headers. Good headers are either too much $$$$ or too small a primary in order to make them fit easier.
