Better find out if his 350 is intercooled.
There is a difference in the intake side plumbing. The intercooled turbo intake has a V clamp bump on it. The non intercooled one only has a bump for a hose clamp. You could use a intercooled intake on a non itercooled turbo. But you loose at least 6psi of boost going this way.
You can not use a non intercooled intake housing on a intercooled turbo. The housing will not bolt down. The intake side impellors are different between the two turbo's.
