I'm like u Dave,
I love to cruize and enjoy the road like the Blue Ridge Parkway @45 mph, but setting at the summer time stop lights shure get hot. I'm gonna build everything possible for my 327 but the problem I have is the 300 DH heads do not have holes for the A/C brackets or anything else so finding the bracket$$$$ will set me back a bit. I have mounts for the P/S box made,and I will figure out some kind of way to mount the pump and pullys together.
I'm sure someone can figure out what to do with the A/C.
Till then I love my vents! Thats why I didnt putty them up.
They are part of my truck and I would not change that for anything.(still hav'nt made up my mind yet about the louvers :))
Good talking to ya,
mike
