Hi! I'm looking for the intake manifold width where the flange sit on the heads. It can be on a 4.6 or 4.4 northstar. I'm trying to get as much info as possible on the 4.4 supercharged intake manifold assemblie.

a friend want to turbocharged his lincoln LS 3.9 V8 and things are tight under the hood for intercooler piping. If the caddy intake can be fitted with adapter plates the 4.4 supercharged intake could be modify into a turbo intake and have decent runner lenght.

I know that the jaguar 4.0 is nearly the same engine as the 3.9 but the supercharged intake have nearly no runner.

Any info is appreciated.

Thanks!
