I'm about ready for paint, when the temp gets above 70 ! Engine compartment needs a new AC compressor & AC hoses yet. The 507 inch Caddy engine is all "tucked in"

Fantastic job -- it looks like it came from the factory that way!

Thanks for the kind words !
The engine is a '76 500, from a Coupe DeVille I had. It's bored .030 over, with KB flat top pistons. I had the heads milled about .025 for a clean-up cut, and had over-sized valve machining done. I ported the intake & exhaust ports, blending the over-sized valve pockets etc, and polished the chambers. The rocker arms are the roller tip Magnum type from Comp Cams, which are mounted on an after-market bar, with studs, and are FORD 1.7 ratio rocker arms.
The cam is a 286 advertised duration type, with .533 lift. It idles "fairly" smooth ....
I have an MSD module in the original HEI, with Taylor wires.
Carb is the original 800 CFM Q-jet, with a tuning kit in it. Since this is to be a daily driver, I have the OEM aircleaner and carb heat ducts etc on it.
No room for headers, since the front suspension was too close. I have the original manifolds on it, with stainless pipes & stainless Borla mufflers.
Even with the stock manifolds, I had to trim about 1/2 inch off of the tip of the bolt that attaches the upper control arm shaft to the frame. Lots of threads on it beyond the nut, so no big deal there. I built the oil pan to fit the chassis, but using the top 2 inches of the original pan. Ihave plans to build a better one, for more than the 5 quarts it hold now.
Trans is a TH400 I rebuilt, with a Transgo shift programmer in it.
It's been interesting !

Nothing wrong w/ stock manifolds. I saw one of those engines in a big Caddy that a friend owned back in the 80's. The car was so big you could squeeze 4 couples in it, well teenagers anyway.
Let's hear it sometime- get you son to take a video!

That Eldo would have a 500 in it. It's a big engine, physically, but folks are putting them in G bodies. Some Eldos have a rear sump pan, which will fit in cars & pickup trucks with that engine.
I have an electric fuel pump in the Elco. The cover on the front of the bed is sealed down good, so I put an access panel in it, to get at the fuel pump and it's relay.
And I added drains in the corners big cover. No other place for water to go, like in a normal pickup truck. I used 1 inch conduit for the nipples welded in the cover, and 1 inch hose going out the bottom.

Here's a pic of the short block. I had it decked to remove some pitting around some of the coolant holes.
Here is one of the heads. I spent quite a bit of time on them, and did some machine work on them with a Bridgeport mill, to elongate the push rod holes for the higher lift cam & higher ratio rockers etc....and mill the bosses off that were for the original rocker arms.
