Few things. Blew 2nd gear out of my transmission so 4L80 swap is being done. Swapped in hydroboost so lower vacuum requirements allowed me to contact Chris Straub for a bit more aggressive cam. Cam swap was just completed in photo above. Needless to say, car is in pieces right now

Eric,

How did that Hydroboost go in? Fairly easy? and how much did it set you back?

The swap was really quite simple. You remove your master & booster and swap the new unit in place. Then it is just a matter of running some braided lines to the power steering pump and teeing a return line in and running it back. I only had to change one of my brake hard lines from the installed power to a pre-bent manual master line (from the master to the proportioning valve on the frame.)

Honestly the most difficult part of the entire swap for me was getting the hydraulic line ends to seat correctly. If I did it again I would take the lines back out and drive down the road to a place that makes hydraulic lines and have them do the ends for me which would have saved lots of frustration.

Price is pretty high with the Hydratech systems I purchased (around $950 for extra long line set, show finish & new master) but you can do it for much cheaper if you go junk yard shopping. I believe you can source nearly everything you need from a Chevy Astro IIRC and have a complete system for just a couple hundred.

I think I still need to install a manual proportioning valve inline to the rears as they will lock up way too early. Just need to dial out a little pressure.
