Narrowing an IFS cross member and fitting a 454 at the same time may not be possible?
Grigg I'm curious why you say that.
Both the IFS crossmembers I have are from big block trucks, so I know they can support the weight. While making it a little narrower does change a few things the suspension remains outside the frame rails and if anything the result would move the crossmember further forward under the oil pan.
I'll have a pro welder do that part so my so-so welding won't be an issue.
I'm really leaning more toward the straight axle with a disk conversion and power steering, but if you see a problem with this one that I can't solve that would end my indecisiveness.
