Late A headers on an early A (smallblock)
I used cheapo headers to make them fit. The ones with the 3 tubes hanging below the steering linkage. One tube on the drivers side will have to be cut out as it runs directly into the steering box and can be rerouted, oh ya forget power steering. On the passenger side, the body is in the way by a 1/4 of an inch so some slight massaging will need to be done on the 4 tubes there and there is one tube below that hits the drag link that will have to be moved over for clearance, I also put 1/4 inch shims under my motor mounts to raise the engine up slightly to help as well. I wish I would of taken some pics back then (mid 70's) and is was on a 66 Canadian valiant that I put a 340 in. with 727 8 3/4 all out of a 70 Duster that had rolled.
But it can be done....
