Wanted 3x00 Exhaust Manifolds & Crossover from a W car

[jmgtp]

I'm not sure if these changed over the years. I am looking to use these on a 3.5L LX9. So I imagine a late model 3100 or 3400 (did the exhaust port sizes change over the years) should work. Needs to have the downpipe connection in the right place for a W car.

The 3100/3400 exhaust manifolds are tiny compared to the 3500 ones, 3500 manis are almost headers compared to 3100/3400 manis

Ya, I know the difference and that the 3500 uses something more akin to a shorty style header rather than the 3100/3400 manifold logs. However, I can't use hte 3500 manifolds in a W car without doing a lot of fabrication. I'm trying to simply my engine swap and the 3100/3400 manifolds meet the need.

I need the ports to match up and the downpipe location to be towards the back of the engine in the W car location.

Bump - still need these. Don't really feel like doing the welding/fab involved to make the 3500 exhaust manifold work in a W car.
