Confused
A few weeks ago, I replaced head gaskets. In the process of tearing things apart, I discovered that my upper intake manifold was cracked, so I thought this would be the opportune time to switch to the GT-40 (explorer) intake. I finally got everything put back together and used a new upper and lower Explorer intake. I reused my stock mass-air meter, my stock throttle body and stock injectors. The only things changed were the upper and lower intake manifolds. I am using AFR 165 heads, E303 cam and 1.7 roller rockers.
I just got back from a test drive, and I feel like I've lost bottom end power. Does anyone else have any experience with a similar swap? Is there a solution?

When I intalled my GT-40 tubular intake only I did indeed lose low end torque.Why? Bascally, you did not lose any actual torque or horsepower, you just moved the power farther up in your powerband. The stock intake, heads and cam are excellent in making low end torque. However, now that your induction is properly set up, you make your power farther up in the rev range. Lower rear end Gears are great for making your car feel like you have gained your low end torque back.

I too have MSD Pro Billet Dizzy with 6AL box and Blaster 2 coil. I knew I had some left in the ol girl. How much hp difference do you think it would be from going from 9* to 12*-13*. Mine is set at 9* base and I think it fell in somewhere around 32* total. I left it there while I was doing other things and didn't finish like I told myself I was going to do. Then I brought back the timing light I borrowed from one of my machinist friends. I just never gotten around to resetting it.
