That's the endgame. Hopefully it's reliable like it was before so I can forget the pain too.

Re: 1987 Corvette Z52
Saturday we did a bunch of figuring. The first was how to get heater hoses onto the water pump that's 1-1/4" from the frame rail. Turns out there are molded 90 degree hoses designed for this, so those have been ordered.
Spark plugs got gapped, anti-seazed, and installed.
Then we went to the air intake. I bought a stock intake from a C5, but I can't find any way that this will work, so we went back to the stock air filter assembly and went about trying to adapt the two together. The end of the molded plastic on the air filter housing used to have a lip on it to accept the MAF sensor and we cut that off to make it a smooth 3.5" place we could clamp rubber or silicon hose to. The current throttle body is 4" dia. I ordered a 4"-3.5" reducer and some extension tubing to cover the big opening. The biggest hurdle is that the angles are not the same. I think the parts I ordered, and I ordered some stuff I may or may not use, will help us deal with this securely.
The upper radiator hose is too short, but has the correct sizes on both ends, so I bought a couple different hose extension tubes that should be able to bridge this gap also. The lower radiator hose looks like it will work with just a small trim on the end.

I love the picture of Fred's big smile in his role as Master Chief of the project.

Don't broadcast that too much. Trump might hang a DOGE badge on his shirt and take him to Washington

Re: 1987 Corvette Z52
Yesterday got the upper radiator hose figured out. I bought a couple different aluminum radiator hose extender pieces and ended up with the 135 degree bend one that seemed to work really well. Only one cut of the original hose and a few extra clamps and we were good to go. There was a hose support bracket on the driver's side that had to be removed, and the bolt for the fan replaced, but otherwise this was pretty straightforward.
The air intake wasn't too bad either, but I did buy several different aluminum tubes and rubber/silicon couplings in preparation for this. It ended up with a 4"-3.5" reducer off the throttle body, and 8" long 3.5" tube with a slightly flanged end going into the 3.5"-3.5" sleeve on the original air box. This rounded flange helped deal with the slight angle that was there, and we used the more flexible of the couplings to deal with the rest of the bend. The two studs that hold the air box down are a hokey design and they would fall out with regularity, so we were able to drill a hole in the tab on each one and screw them down so they wouldn't fall out anymore. No picture of this upgrade though.
I had heater hoses on order, but despite being shipping on Monday from Colorado, the USPS was unable to get them to me by Friday (or Saturday for that matter) so that will be one of the things for next week. I also bought a 160 thermostat, but realized when I went to install it that my car has the integrated thermostat/housing combo. So I'm going to by a rotatable one to get the angle a little better on the lower radiator hose and this should accept the thermostat that I already bought.
