T56 Magnum Conversion

Are those Doug's or TTI headers?

I took a look at the new gearing for that transmission, that's nice! I've got a TUET11009 for mine, 2.66 first gear, which is down from the 3.09 I have now. But I've got a set of 4.30's to install in mine when I do the conversion. With the cam in my 340 I can't cruise at 1,800 rpm anyway. Right now with the 3.55's I'm turning 3,300 rpm to pull 70, with the T56 .63 6th and 4.30's it'll still be down to 2,500. Much below that and I'm out of my power range anyway.
