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?? |
So people are using the LT2 manifold? I thought there were reports of it not fitting or working?
I'm not sure the MSD could be good enough over the stock manifold or gain enough power to justify its ridiculous price tag over $1200.
