Exhaust choices?

I have a '62 Ranchero with a 4.1 x-flow. I believe it is stock.I have a front exhaust pipe from my 170 on it. The pipe is 1 7/8 and I think the bend is a little wrong.I believe the pipe should be a larger diamiter.The question is can I buy one for a newer american 250 six that has the right bends. Or will I need to make one. Thanks for any thought or ideas, Ken.
 
No, not exactly, as the Us 250 has a low mount starter, but as long as its not a down pipe form a later 4" converter 250, you'll be good to go.

The 1968 and 1969 Ford Ranchero and Fairlane pickups used the US 250, and any thing 250 should allow the cross flow header to hook up with ease.


The later 78 to 1980 200 and 250 exhast manifold, before the big 4" primary cat system in 1981, was most likely the same diameter and postion as the Australian cars. Ford made no changes from log head to cross flow in the exhast, same postion. All cross flows were US 250 for height, but US 200 for starter postion, but it was shifted out further as well. A 200 down pipe sits 1.572" too low compared to the Aussie 250. The US 250 sits 89 thou higher.

Here is a barn tech late US 250 with the 4" cata exhast and F150 air cleaner to compare; the kink in any 1968 on 250 should clear the X-flow.
