When I was young I had a 472 caddy that could lay rubber for a half a block!

Hey Courtney, great video - thank you. Sir, I have a fresh rebuilt "stock" 472 in my 1972 Cadillac Sedan. It needs to be sharper off the mark and through its range. The base timing was set @ 8 degrees, I have gone near 12 degrees. Not a lot of change, but there's no pinging or engine knock, so could I wind up a bit more? or would 12 degrees be it? We run a 98 octane fuel here in Australia. Help appreciated. Cheers Courtney - Fletch, Classic Restos TV.

If you upgraded the valve train, you think you could get to 7000rpm?

Mine stays stuck open

Good job, very impressive. AG

I deleted mine for less extra stuff under the hood

I got a parts car the other day. It has an Edelbrock intake, is it worth putting on. 472

,,,,,owned and daily drove 472 cadds for 12 years......At the biker bar ; One yelled out to me ; Tommy Horse only guy with a cadillac that runs like a Chevelle.........Love to find a 1970-71 or 1972.....and build another ..........600 plus foot pounds........BTW,,,Only had one tranny failure thru all those years ,,,A broken sprag,,,,,,one way roller clutch.......Drove my car home in reverse gear ,,,,,, 7 miles.....in 1988 or so.....

What cam sir?

Im sorry to hear about Courtney. My thoughts and prayers go out to your entire team. God Bless

RIP Legend!

Awesome video and info I used watch a lot of Cadillac's street racing in Fountain Ave and Hunts point in the Bronx and there where some bad ass Cadillac's back in the day with the original power plants they came with and you could get the performance parts to upgrade the the 472 the 425 and the 500

I am very skeptical about those pistons. Tried them in 455 Buicks a few times and had a set fail and the other motor had piston slap. We machine exactly to there specs. Now i just use stock replacement or forged. I prefer the forged

I have 2 or 3 472 motors. Been looking for a 500 crank. Maybe i wont bother

I gave this company a insane amount of money a got a pile of a engine. The first engine I got the cam bolts fell out and it was destroyed. The next one had rocker noise and a oil pan leak. Sad company that sells dinosaur boat anchors. Get you a LS way lighter and cheaper.

have a stock 5.9 magnum engine, 9.580 deck height, based on my calculations the KB107 4.000 piston would be above deck .008. I checked #1 stock piston, it is .044 below deck at tdc, and looks like a chamfer of approx .035 at top of cylinder. Do U see any issues, other than thicker gasket for proper quench..............

Better numbers than the GM crate 502. What a torque beast this is, as you say many overlook these Seen them in many pickups as a kid in the 70s. GUys if he makes his living this way he isnt going to hand you his cam specs...maybe sell you a cam?

Torque correlates more to piston diameter than to stroke. The 472 has the same bore as the 500 so it should be very comparable in torque in most situations 😎👌

How much of increase in HP is due to the 30 over ? I'm thinking, not much. The 10:1, the heads, the carb, cam are what give you the Power, right ? IDK, I just read and watch a LOT. That engine sounds great !

I think this will help me. Going to remove the valley cover and check the distance as you’ve shown.

I don't understand why you would not list the parts used for this build (that you are trying to sell) in the description box. At least give us cam specs or your cam part # along with what octane fuel you used please...

Thanks for the info

Thanks for the video info. I used to have a 76 Fleetwood with the 500 and loved it. Just bought a 78 Eldorado with the 472 so we will see

How much would one of these cost as a turn key engine?

Same as a big block mopar seems similar

I have an AVS 2 on a 406 sbc of around 400hp. It is behaving exactly as you described, ie; it has a momentary lean stumble when I get hard on the throttle. The first time I tried to adjust the spring tension I didn't realize I needed to hold the adjusting screw while I loosened the set screw. As a result the spring immediately released all its tension so I lost my baseline. I have tightened it 2-3 turns from that point but the engine is still stumbling. Is there a baseline number of turns from which I can then begin adjusting? How much resistance should I feel when opening the air flap with my finger? Thanks for an advice you can offer.

Sir I have my friend car cadillac 1966 have sound chain how can repair

How are you

What is the firing order step by step I'm new at this

Where do the wires that were connected to the old ignition coil go on the new HEI distributor?

How many check gam standerd size

World greatest and cheapest ring squaring tool is a 1” roll of masking tape. Simply remove tape until it fits the bore, put the ring in and push it down until the roll is flush with the deck!

Staking the plugs? What does that mean I’m currently building a 500 and I’m putting in the oil galley plugs and don’t want any big problems later

Thank you for your knowledge 💪🏽

What’s the full build list of this?

Great knowledge, thanks for sharing!

Holy shit that torque curve is magnificent! Flat as a table top right off idle and over 500 all the way! You got that tune down to perfection! What is your total timing on this setup?

🥝✔️Richard Holdener and JA Cook from FEP brought me Here. Love your stuff, Courtney. Proper info rather than a One Flew over the Cookoo Nest Frontal Labotomy. Ford copied that joined system for its Thermactor in 1978 to 1995.

I had a 1970 Deville 2 door my senior year of high school in 1981-82. I am hunting for a similar car. Good times good times

VERY VERY COOL .

Thank you for your knowledge 💪🏽

Is this system available for 67 429 Cad ?

Thank you for your knowledge 💪🏽

Very cool brother! I'm glad to see this!

Thank you for your knowledge 💪🏽 🙏

Richard Holdener brought me here. From New Zealand 🥝✔️🙃

Nice video!!, can you do one on choke adjustment? Thank you

Great short video

Cad Co have a part number & price dir a caddy 425 v8 main cap girdle??
