Nice video. I have talking with Julius is the past. He recommended your company for parts and experience on these caddy engines. It was a pleasure to watch the video.
Ported heads $2350+, ported 2115 Intake $625+, small hyd roller cam & kit $1695 puts it at $4670 for just 3 parts. Theres got to be a way to hit just 450hp & 600tq for the cheap. Yes its probably 125-130hp more than stock but the TQ would only be about 100 more. Ive saved a 500 caddy an dear old friend of mine started but never completed. Ive added the kb pistons/comp 268h cam w/valve springs setup/2115 intake/1& 7/8" long tube headers. Surly i can get it close to 450/600. If not, ill blame the cam & try one of your small hyd grinds. just venting ~
Howdy ... I am building a 500 caddy for a direct drive airboat. I have a 1975 engine i just tore down to block. I have 120 cc heads as you know. My max propeller RPM is 3000. I want to spend the time and make this the best Direct drive engine i can. I am prepared to port and polish my 120cc heads and put larger valves in them.. I am looking for as much torque at 2500 to 3000rpm as possible. Would larger valves help me there?? And what upgrades would you recommend ? Thankyou in advance
Great video do you know of any 500 or 472 heads that will fit on my 77 425 I'm rebuilding looking to build a stout street motor out of it making 350 to 450 hp out of it any help greatly appreciated
Here's a question, which I'm curious if someone could answer. What would happen if you ran round dish pistons from the 1974-1976 500 in an earlier 76cc heads? I know obviously the compression would be absurdly high, but I'm curious how high it would be, and would it run with stock valves, or would the difference in valves create a problem with that piston?
Can't find any email address for cad500parts. My english is not so well to make a call. Want to order some parts for my rebuild and shipping to Austria / Europe. Thank you for your answer.
I first had a 71 Coupe De Ville 472 in my 79 Cutlass. Great engine. Was low miles. Ran well on stock Q-jet on 93 gas. Later found a 68 472. Then a 70 Eldo 500. 10.5 -1. Sold car with that engine. If I can find another G body. Need to dig out the 68 472 from my brothers engine pile.
Do you guys give advice on builds over the phone? I have a 1969 472, I’m looking to build a low RPM torque monster. I’m very willing and able to put some money into it, and send them in for work to be done to it. Any info helps, thanks.

@@dirtcheapmedia3390 couldn't get my hands on one. Ended up selling it because I bought a house and I'm about to start a family. Got myself a PPV Tahoe from an auction, modded it a little bit and got my wife an Escalade. All is well.
I would love to hear more about the roller cam you used.
Your knowledge is invaluable. Please make more videos

Great Video, I've done quite a bit with Cad co , he knows what works!. I'm working on an engine install now that he built for me.
Great info, and perfect timing. Have a 500 motor I'm just starting to get into. Thank you.
I was a cad guy back in 1986

Yes any of the 472, or 500. Swap the rest of the motor with it
Steve Magnante from Hot Rod Magazine story will validate his logic!
Great info. More vids please!
