Ok so i finally got the 403 in and bolted down, now, i bought a set of headers for it but i dont think they are going to fit (without a bunch of fabircation) so, the stock manifod i took off has a (i think) cross over on the left bank (looking at it from the front) is there a set that does not have this crossover, would make things a whole bunch easier.
Thanks

Just so ya know i used a set of engine side mounts off a 79 T/A and had to space them out a bit and it popped right into the origional frame pads on the ole 77 Silverado! Thanks for the help fellas!!!!!

 

I'd just cap the crossover and run dual exhaust from the rear ports.

 

A 403 in a truck. Seems like the headers should have fit but the solution you mentioned has been done in B bodies that have the rear steer interference problem. Should work fine.

 

Thanks for the quick replies, im a bit of a dork on this stuff so how does one cap the crossover???

 

This is one way...

FYI, all SBO manifolds were configured with the crossover, even the W-31s.
