Results with Box Upper on my 347 verses Cobra

[8850]

gp001,

No problem. Hope my tests will help others not make the same mistakes I have made.

My next step as I have mentioned is to install the 1 3/4 Hooker long tubes and get an et. Assuming I am going to pick up et as everyone has told me I will, then I'll install the Victor 5.0 intake and compare it to the Comp Cams box I now have. The one that loses will be forsale. My killer GTP 75 mm inlet Cobra upper has already lost by about .37 seconds to the box. Both the box and Cobra upper were on the same ported Cobra lower. I actually welded the lower and ported it to 1262 Fel Pro. The only limitation there is the round 1.65 diameter opening in the lower. Hopefully the Victor 5.0 will improve et as so many have told me it will over the box. I hope to have a GTP ported Cobra upper, ported Cobra lower and a GT40 box forsale.
