  • This time they find a junkyard Cadillac 500 big block and use some modern-day performance parts to make a monster out of GM's biggest luxury car engine. As expected, the final truth is in the dyno numbers.

    I spent over 40k on several 425s and I finally got a 500 caddy that was super built up. 500 hp 600 torque built by cad. Co. In Albuquerque. Yes they dynoed it.
    The problem is very few people can build them properly. Yes they make tons of torque but you can get a crate motor with warranty to do the same that is lighter. Once you started getting more power out of these engines with bolt ons and cams look out your wallet will look like a Ethiopian. I had 3 caddys I drove over 24 years. I worked on them nonstop. I also rebuild the transmission, differential which was a posi diff out on a caprice, brakes, suspension you name it I did it all. That Ole 1979 caddy with that 500 could outrun just about anything. It was a 500 swap. The engine I had out probably 8 times and the th400 took 2 hours to get out and I'd have it completely disabled flat. I know every bolt in that car top to bottom including torque spec.

    I can say for my own build these don't cost hardly anything to build. I'd guess I have $4,000.00 in mine.
    I used 440 Mopar rods. Had the crank offset ground .100" and narrowed the rods to the Cadillac width. Bought JE Pistons .020 over and Mopar pins. Reground the cam, BB Chevy valves and ported the heads just a bit to blend the valve job. Stock Edelbrock manifold, swap meet 850 Holley. Rockers came from Canada back then. Plain old oil/fuel pump. Absolutely nothing in this engine. 9.5 compression.
    It was a brute. An absolute Brute. 5400 rpm and it drove so different, it wanted tall tires and 350 gears. It wanted to strain against a load to really get it done. -- You may make a lot more power with other engines, but I don't believe they will out pull one of these for the smooth steady rate of acceleration on the street. Don't need money at all to me.

    Though it was stock, we shoehorned a Caddy 500 w/it's turbo 400 into my 1968 GMC that was a 6 cyl stick shift. The truck had a 3.73 gear. That truck could pull Mt. Everest if you could hitch it to the truck. That motor swap lasted close to 20 yrs before biting the dust.

    I read a series of articles in a car magazine, don’t remember which one, in the early 2000’s about building a Caddy 472/500. I had a really nice 64 Chevy step side with a 305 in it that was getting pretty tired. Found a late 70’s Caddy with 78000 miles that ran pretty good but the suspension and wiring were shot. Bought it for $200, pulled the engine and transmission, and sold the rest for scrap for $100. Rebuilt the engine, had a valve job, put in a mild cam, Edelbrock intake and carb. What a beast of a truck! It would spin tires forever with the light bed. Sorry I ever sold it.

I went from a Max Wedge Indy heads and single plane EFI intake on my 500 Mopar, to a longer runner ported Edelbrock Pro Flo XT intake with standard port TFS240 heads, and gained approx 40 ftlbs at 4400 rpm. With nearly the same cam specs at the Caddy, the Mopar (installed in a jetboat) turns the same spec'd Scott Jet 912 drive at more RPM than the KEM LT4-650tq/650hp marine engine.

      Because bone yards primarily have been taken over by scrappers looking for a quick buck - they no longer care about selling parts - especially for older cars.
      I just sold a bone yard my 2000 ford taurus with the HO 3.0 32 valve engine and the just crushed the whole car for 3600 lb at $0.10 a lb - that motor and transmission were worth 3 X that - the factory aluminum rims were worth $100, the never wrecked body parts were worth $1000...
      They scrapped it for $400 along with who knows how many classic cars - Caddys were all crushed decades ago by these bastards

      @nerd1000ify 2 года назад

      Honestly if you drop some modern tech into one of these engines you can probably improve the fuel economy AND the power at the same time. In particular with EFI you could add some compression ratio and timing without having to run special fuel (Without ITBs or very carefully designed manifolds carbed engines usually have some cylinders running lean and some rich, and your compression/timing is limited by the leanest cylinder) while also improving your economy. Also those alloy heads have a modern looking chamber that probably does a lot of good for economy and power compared to what was available in the 70s and 80s.

Comp Cams doesn't make a hydraulic roller conversion kit for it, Mahle doesn't make 11 to 1 pistons for it, Cometic doesn't make gaskets for it, Edelbrock doesn't make an aluminum manifold for it, No one makes conversion headers for it, I can't find a flexplate or adapter to mate my 6 cylinder Ford-O-Matic to it.

    Heads need loads of porting
    Won't run on pump gas with early heads on later block
    Q jets suck
    Force induction will wake these dinosaurs up
    Valvetrain blues are present
    They coast way more then chevy bbs
    The blocks are awsome in strength due to a thick bore and hight nickle content
    4 bolts not needed
    Cam choices were limited to regrinds back then
    A few failed from oiling issues
    Don't use the rear sump with long pickup
    The p rods bend easy
    Don't use the cast rods go with modded olds 455 rods.
    The height won't fit under the hood of most cars.
