TP, it's interesting that you bring this up because I just got my setup up and running and seem to be experiencing the same things. I have a Clifford heated intake and Clifford shorty headers, a stock Edelbrock 1405 carb. I have a T-5 in mine, but really don't get a chance to use the 5th gear much. Right now I can't accurately gauge mileage because the speedo gears in the trans are wrong for my 3.73 rearend (305 Camaro used a 3.08 rearend I believe). I do know it doesn't heat up too well in the cab though. I've recently cleaned out my heater box also. Oh, another thing I've noticed is that my temp gauge is usually at the 1/2 way mark with the occasional trip to the red and I've got a 180* stat in there. Once I bleed out all the air out of the system it'll probably stay at the 1/2 way mark on the gauge.
Put that Q-jet on. I'm VERY curious how it'll work out for you. I've been waiting very patiently for you to do this, lol.
