could the intake be holding my low end down?

I had a very similar combo that went 106@3650 with a manual trans. But my 60ft was in the 2.4x zone. At 185psi, the bottom-end was killer strong. This with a 367 @ 10.95Scr with OOTB Eddies, a 270/276/110 advertised/223/[email protected] cam, 3.55s, and a 7000 redline. Why 7000? Well I thought it prudent to quit somewhere, not that the engine wanted to. My timing was 14 initial, 28*@2800and all-in 34*@3400. Full TTI 3" exhaust. Rpm-AG and 750DP. I only completed one run and hit 12.9x. I was and still am running 1.6 arms. I doubt my combo had more in it, except for the lazy 60ft,lol. I was running 245/60-14 street tires,lol.
So Ima guessing our combos are pretty similar.
Well, were. That 223 cam died in 2004, and I swapped in a 230* in it's place . Now I shift at 7200. and the combo went 93 in the Eighth, still with a 2.4x 60ft lol, 325/50-15 BFG DRs this time but same street suspension,lol.

What was the ET?
