Headers installed with pics!

[redz 1970 K5]

I broke down and got my Thorley's installed at a shop yesterday. I have other things pending their installation, so I went ahead and had it done.

I have to say, the fit was pretty dang good. I am glad I wasn't the one trying to tighten the very back bolts 1/8 turn at a time from the bottom! The y-pipe exit is a little close to the x-fer case crossmember, but no real issues. The pipe clears the driveshaft for the lift great and still stays tucked up nice.

The SOTP dyno showed definite gain. Off idle, there was definitely more there, which I wasn't necessarily expecting. The truck pulls much harder without question. I know people question headers sometimes, especially on stock motors but there were gains there no question.

Come to find out the pass side exh manifold was cracked all of the way around and was on it's last leg! That helped justify the new exhaust.

My only problem now that I noticed this morning is the transmission shifter won't shift past OD, so the shift linkage must be obstructed somehow. Bummer. I will need to look into that, but it's snowing so that is a deterrent...
