Got the shortened driveshaft back and installed...…… Took the old firewall bracket and modified it to accept the existing Brake swing pedal assy and the new Hydra-Boost assy........ I also moved the assy 1" further away from the engine...... Had to cut out some of the contoured area of the firewall to get everything to fit correctly.......so I have some sheet metal work to do but it fits perfectly and was worth the effort.......

Also I have to say that the Holley front drive setup is probably the "Best" Engineered unit I have ever used...….. It's a work of art !!!!!!!!

Oh, the poor people who own this car are going to throw themselves through the windshield with that hydroboost instead of that crappy dual diaphragm booster. Hope they have seatbelts!

Moving along...…. Had to make a Firewall spacer for the Hydra-Boost to get the linkage to work out with the brake pedal...…. Got the steering column mounted to the firewall also...…. waiting for some other parts to show up to finish the shift linkage...…. Decided to put the Radiator back in and see what problems were going to come up there...… Bolted it in and everything worked out, enough room for everything to fit...…… Just have to run dual fans to clear the water pump (ordered)…… Time to start on the rewire....

kwizz Nice work. I've seen your past builds and really admire your work. I'm about 90 miles north of you on the coast in Manitowoc and would like to visit you some time, that is when this whole covid virus is over. This would give me the opportunity to put some more miles on my 66 Chevelle restomod/ LS1-4l60e. But for the time being,I guess were all forced to spend time creating new, or refining our own projects.What a bad reason to have to stay home.HAHA.Social distancing is very similar to living in Wisconsin in winter.

Went over to Frameup and Donnie gave me some mock-up A/C units to see what would fit...….. Ended up figuring it out and got everything ordered...… Got a condenser for the radiator that they had in stock …….and got it and the electric fans mounted...….. Got all the fittings and lines for the Transmission cooling system...… also started plumbing the A/C lines...….. Waiting on more parts to come in to continue...….

Well..... The car had a small block Chevy installed in it some time in it's past....When the frame mounts were welded in at that time it, ended up that the engine was off-center about 3/8" towards the drivers side......… Fast forward...… After installing the #605 box and grinding some clearance on it to clear the exhaust manifolds (seemed like a good idea and a simple fix at the time)…… Anyhow...… After moving on from that point, I noticed some fluid on the floor below the steering box but I wasn't too concerned at the time because after cutting the brake lines in that same area after removing the old braking system I thought it was brake fluid...… Wrong.... Darn.....
So, after removing the box and looking closely at it I seen where the leak was coming from.... Ground a little too much off the box..... Double Darn !!!!…… So we get back to basics...… LOL..... I'm making some new mounts (Pic's to follow) to correct that issue which will remove the steering box clearance issue and center the engine...… This car stuff is hard sometimes...… Should have this corrected tomorrow
Also.... The Rick's Tank showed up today.... They built it for this conversion as a passenger style tank as we requested and I will have to remove the spare tire well in the wagon to allow for it's installation...… More Fun...… LOL...…








Got the old tank out...

I think you and the owner will be happier in the end by revising the engine offset Ken, I’m sure that was previously to clear a specific component used in the old SB Chevy swap. I can’t think of a single good operational reason to offset the engine towards the driver side of the vehicle.

Made new mounts and welded them in...… The engine is now about 3/16 towards the passenger side, so I picked up a good 1/2" of clearance on the drivers side..... The new steering box (ordered) will have plenty of room without any clearance issues…. I also leveled the engine as it was down about 1/4" on the drivers side...… Now I can sleep at night.... LOL...… Still waiting for parts to complete the final needs of the engine compartment...…… Time to get rid of the spare tire well and get the new Gas Tank installed
