and I thought the 240 manifold flowed better... some forums that come up with you search for info on the manifold swap have people saying the manifold swap makes like 20 more HP... I don't know what the trucks put down stock, so I don't know if it is even a reasonable claim... hell, that 20 hp probably just comes from a non-leaking intake manifold gasket....
no the intake manifold doesn't add any flow/hp. Its the cams that are different and causes the power increase from a truck motor and car motor. I went through all of this stuff when I was driving my d21. It turned out that 90% of the stuff posted is horse shit.
