Re: Stroker's Build (5.3/4L60E in a '69)

Uh Oh...somebody got a Hydroboost!!

This is working out great for me so far. I didn't want to screw around with any adapter plates, so I just lined it up on the firewall with the stock pedal assembly, and marked some holes to be drilled so that I can just mount them together. There is some minor drama with the top holes, because they ended up so close to each other. I think I will weld some tabs to the very top of the bracket so that I can use the stock studs that come through the firewall. Another great fitment is that one of the holes for the steering column mount will be shared with the HB plate. Score one for me!

Since I chopped about 2" out of the brake pedal mount because of the smooth firewall, the brake pushrod went together great as well. As you can see, the stock pusher was just a bit too short. I chopped it back to the rod portion, and the stock clevis slid right over it without much wiggle room. I'm going to wait until I get it fired up and operational to weld it together so that I get the adjustment set up just right.

For the hydraulic lines, I'm going to be replacing those busted-ass rusty Astro lines (which are too short anyways), but I'm not going the Earl's powerflex route like everyone else does. I have something else in mind that is about 10x more cost effective and proven to work. Of course, like everything else, I'm not 100% sure it will work for this application. I'm going to keep a lid on this until I can prove that it works or not. If if does work, I'll be into this HB setup for about $80 total, and I'll let the cat out of the bag so that you all can save a few pennies as well.
