Just for my own edification, because we are talking about numerous manifolds here, is the 440-3 the new one that Indy sells on their website?? That is the route I have chosen, I don’t want to use a spacer. Thanks
440-2 RB 4150 440-3 RB 4500 440-3X RB 4500 taller and extra plenum volume.
440-3 has been for sale for a while, early ones seemed to be a plunge cut -2, later ones a dedicated cast 4500. All are single plane, part #'s seem to have changed on the new website though
Thanks for clearing that up....i was getting confuse
