Well on to the AC pump. This might be interesting to people who want AC on their swaps in the stock location. I have seen people put stock truck AC pumps in and they fit without frame notch but its good to give more options.
Since i am changing the AC pump from running off the 4 rib where it was, to the 6 rib on the main drives to make room for my blower drive, I have to move the AC pump roughly 1.25" forward. That is accomplished by some plates to be fabbed later.
I am using a 00 ish s10 compressor. Already is 6 rib and compatible with GM electronics. Funny thing is too- it shares the pattern with the stock LS truck AC pump minus the top rear bolt! I ground off about .9" from the old mount face to the new mount face to account for the one offset mount. IE the other 3 bolts are in the same spot, GM moved that last rearward one up and back, and away from the mount flange that .9" or so on LS. I am going to use the stock 3 bolt pattern and space them forward, and modify the last upper bolt somehow to tie into the block.
Other issue is the VERY close gap between the frame and pump, there is just under 1" between so fittings will be tight. I think 4 seasons has a fitting I need I just need to make sure its the right hose size, i cant remeber if GM uses 8 and 10 or 10 and 12 AC hose line size.
Also, I included pictures of valve cover to AC box clearance and PS pump to stock f41 steering box clearance. I have a hole in the AC box yes but that was from me dropping the engine in the bay a bit too hot. Just needs to be riveted back in.
What I am getting at, is if you buy LS swap mounts and your stock truck pickup SUV whatever power steering pump pulley hits the steering box and you have F41, you don't need smaller pulley, you need frame mounts not designed by morons who moved the engine way out of where it should be. I built my own mounts with a sharpie, band saw and a tape measure and T square. I am determined many companies making mounts have never heard of the statement "put the important stuff where it matters and fill in the gaps"
Anyways!
