What would have been the HP reading with a 340 driver and one of my machined manifolds with both manifolds having a 2 1/4"+ exits?????
That’s a great question right there.
I have a set of trebligs manifolds I’ve been dying to install. A 73 340 driver side and a jgc passenger side milled out to nearly 2.5”. I just finished the k frame and suspension upgrades and install. I cut out the old rusty, caved in headers and have just now installed the manifolds. I expect the 5.9 magnum with a bit larger cam and airgap will perform just as before as a streeter with the occasional 1/4 mile run. I love the manifold look and the tremendous amount of room that’s been freed up by removing the headers. I’ll get some pics later today and post them up.
Thank you Gil.
