500 ci with heads, cam, intake and headers only making mid-200's NA? I can understand in the motor's original restricted state back in the 70-80's gas crisis era, but free'd up with some modern day parts that seems awfully low, no?

[@johnclark6139]

yeah with a lot of their builds they say it’s “budget friendly” so they’ll reuse some parts, but they always use the garbage parts that should have been thrown away, and they ended up spending MORE than they should have

[@salninethousand2496]

500 Caddy was not designed to be performance motor, like the big block Chevy, or even the big block BOPs. It's quite limited by low RPM valve train, small valves and decidedly non-performance heads. Here, they didn't touch the pistons (i.e. still very low compression ratio, plus there's bound to be some blow-by) and a cam only slightly larger than stock (peak power at ~4500 RPM) is never going to make a bunch of power. Stock, this motor had ~150 rwhp, so the bump to 250 rwhp is 67%, which is excellent. Factor in losses and this build pretty much duplicates the MY1970 400 hp 500, so not too shabby all in all.

[@bertgrau9246]

@@salninethousand2496 I agree, over all its pretty impressive, plus it's something you could use as a daily driver if you wanted to. I have a 76 coupe deville it was rated at 190, horsepower and 350 torque so they did a pretty good job. I really like the sound of the Q-Jet at wide open throttle (with the air cleaner lid up side down )

I was expecting at least 500BHP and 500FtLb from that 500CI Caddy.

[@zarbog8618]

I didn't see how they built the motor. They said in this video, that they put go fast goodies in it. Looks like they bought the cheap go fast goodies. A pony per cube is not an unreasonable ask at all. And that's a naturally aspirated benchmark. Throw in some happy gas and it should be well north of 500 IMO. I don't remember who did it I believe in the 50's. Think it was a Chevy 283 that had one pony per cube.

[@russelldesabre9530]

A STOCK 70 500 cid had 400 hp and 525 ft......

[@TrumpAmerica-2024]

a stock 426 from the late 60's - early 70's had 500 hp

[@TrumpAmerica-2024]

@Allen Tokyo yes they did. they were advertised with lower hp numbers to keep the insurance costs down.

[@13coyote13]

@Allen Tokyo The Hemi's stock rating wasn't its peak horsepower only the horsepower at that rpm, 425hp@5000rpm, 494hp@5950rpm, same as Chev did with the LS6, they rated it 450hp at a lower rpm when actual was just over 500hp at a higher rpm. Mopars 340 six pack was rated at 290hp when actual was 356hp and with a set of headers jumped to 376hp. Manufacturer ratings were purposely low for government and insurance reasons.

[@jeremymann8930]

I feel like a bottom end rebuild would have been a big help, those breathers are huffing pretty good

[@Thundarr995]

I'm not surprised that the power numbers are kinda low. My friend had a 76 Eldorado with the 500 CID that he tried to turn into a sleeper. He couldn't get it to do what he was expecting it to do,it was a dog. I think he expected it to have alot more power than it ended up with. Eventually he gave up on the Caddy engine and dropped in a mildly Hot Rodded Olds Rocket 455 out of a 70 Vista Cruiser. That engine motivated the Eldorado much better than the Cadillac. I made and welded in the engine mounts. His father used to be really into Oldsmobile cars,and he was part owner of a wrecking yard from 1974 to 1997ish. They had all kinds of cool stuff laying around/ available.

All that work, and it's basically back where they were Pre-Emissions? FFS, 500 cubes, with a modern cam, decent flowing heads, and a basic multipoint injections system, Should be in the 400hp and 500ft/lb range before the NOs hits.

[@the-dullahan]

I mean, even without all that modern stuff. A 1976 590 built to factory spec has 397 HP and 488 TQ. These guys just downgraded to 425 heads for some reason, making a "performance build" that actually had less power than stock. The heads don't even line up either, which is why we all watched it blow up at the track the first time they came out to film this (hence the 90 day delay for a reshoot and the "redemption" arc because we all laughed at them.)

10:13 They were rated at 400hp in 1970 before they put low compression pistons in it (8.5 vs 10.25) Makes you wonder if these 200hp versions are just a piston swap away from making 400hp when freshened up.

@@pookysdad4884 drivetrain takes about 20% give or take, so you can ballpark numbers. 400 at the crank would be around 325 at the wheels. 400 at the wheels would be almost 500 at the crank and probably too much for the stock bottom.

I need to go back and see what you did to the engine. I was pretty disappointed by the NA output. For a heads/cam/intake 500" big block engine, that's not a big improvement.

[@EricErnst]

~200hp stock. Add 5 axis cnc ported big valve heads, shaft roller rockers, bigger cam, and aluminum intake and she only makes 238hp at the wheels? In the initial video, you claimed 1hp/cube and over 700lb/ft. That would be cool. This is very underwhelming. kzbin.info/www/bejne/pnuzl6h-lLNmjpY

[@the-dullahan]

They put out less power than this engine had stock. The problem with their build is they used 425 heads which not only have crap compression, they have absolutely TERRIBLE airflow. Even worse, they don't even line up with the 500 block, so when they came out to the track to film this episode the first time, the whole engine blew immediately. So they quickly rebuilt it to refill it a second time (hence the 90 day delay between episodes and the "redemption" arc where they keep talking about "redeeming themselves" now.)

Not I'm pressed with the NA power. That's a lot of motor. Should have made way more grunt.

[@Bolton115]

Agreed. Would have done better with rings and bearings and degreeing the stock cam to compensate for how retarded the factory made it. Then the proper block deck and gasket mods for 425 heads on the 500 block. Those two cheap and cheerful things would have netted them more grunt than the cam did, because those old rings were tired even before the old cardinal rule of never put fresh vslve job atop wasted rings was broken.
