I was thinking this too, the MSD has a reasonable runner length. I do like the barrel design (speed master), the problem with the design is the lack of plenum. So we are back to a LT2 like manifold. I don't know why MSD did not extend the runners further on the LT1. We can look at their atomic LS3 and see the runners go to the opposite bank (it is almost like a single throttle body cross ram).

The only fix is to go cross ram:https://www.jegs.com/i/Edelbrock/350...MaAtFjEALw_wcB


I would speculate, that a crossram would indeed be the NA go fast norm over the next 5 years.


For the LT2, I like it but think an aftermarket version with more plenum width (extending over the heads) would yield more power. GM has packaging issues that a LT1 Camaro intake does not have at least for the front 6 cylinders. So maybe a LT1 specific intake would need to have the runners angled forward say 15 degrees... get some outside the box thinking on the subject.




I will also say this: the ported MSD seems to work well enough given a big cam, not as well as a hi-ram, but at least it fits under the hood. Still don't why MSD did not to the LT1 intake more like their LS versions??
