Shame on you ! a LZ1 weighs less than a small block, but it cost a little more than the "cadplant"


Their is a guy that specialises in big cads. I dont know his address but I remeber that he makes special swap pans, mounts and a header flange that can be welded onto a normal BB chevy header ( after its flange is cut off). You will need an adapter to use the chevy trans on the cad bell housing but they are rather cheap and available.


You know if you do it no chevy owner will ever talk to you again..

P.S. Cadillac is building a roadster that is bolted on a late modle C5 Vette. It shoud be out next year. Its ugly too.

 

it sounds cool and shouldn't be too much work once you get the kit. do a search on the net for the company that does the cad motors. he offers cams, and intakes also. my mothers boyfriend did this to his 68 nova, this thing was an absolute torque monster. the tire would light up at will with a posi in the rear. the only problem i might see is tring to keep driveshafts(axles)in your vette. good luck and have lots of fun!!

Is that LZ1 or ZL1 the sleeper corvette option from the late 60's which produced almost 600hp. As far as I have read on them only 2 were actually ordered from the factory though the truth could be otherwise. The ZL1 is far out of my financial league.
THe cadillac BB stroked my interest because of a article I read in HOT ROD NOv "99. It says on pg. 47 "Plentiful and cheap, the cadillac 500 is an absolute torque god that weighs in at a mere 595 pounds-40 pounds more than a chevy small-block!" Further down the article reads "Caddy to GM intermediate swap kits are readily available; the universa-fit kits stick a Caddy into vitually anything on wheels."
Let me add that the 1970 cadillac 500 with its 10:5 compression produced a wopping 450 hp and 572lbs of torque. The 500 cu inch motor lived from 1970 to 1976. Cadillac Motorsports development and Maximum Torque Specialties are two of the companies producing these kits. I also heard of Caddi motors being put into chevette's and raced.
I am looking for the biggest bang for my money and I am tired of these young mustang driving 5.0 teenagers eyeing me at red lights in this town and I look forward to a time I don't have to slink away from them

This will be a great adventure it seems to me. Both of the above mentioned caddy people know what to do I believe. I have a very little 500 caddy experience to offer. All of the 425, 472, 500 motors use the same bolt up castings for heads. the 425 head on the 500 would give you about 10.5 to 1 compression and the 472 head would give you over 12 to 1. Not bad for just switching these cheap heads but they say that the bottom end is not real strong in it's stock form. Please let us know how the adventure goes.

I own a BB 73 vette and think the chevy would be an easier swap (bolt in).

By the time you buy the adapters a 454 would cost less. And 450 hp from a 454 is easy.

Just my opinion

I'd have to agree with TRW that it would be so much easier to stick with Chevy and just go to a 454. Easier swap, cheaper parts, easier accessibility of parts and just as much HP and TQ easily attainable with minor mod's. I had a friend tell me how the Buick 455's produced more torque than a 454 and I said yeah about 8-12 FT/LBs which is nothing that a little cam change or intake or carb or slight head work or anything else very minor couldn't take care of. The Stock Caddi does sound impressive and would be unique but it just depends on how much time you have to do all the extra research and find all the right parts and the extra money it would take for all the extras needed to make the swap work. Sounds like the beginnings of a real headache to me. LOL Just my humble oppinion.

 

Hey dellerbe,

Be careful thumping on them Buicks, cause some a them suckers go and I mean in a big way. And in BIG CARS, too!

It don't take much at all ta put a '73 Deuce and a Qtr. into the 11's.

I wish I knew just what all the engine ratio stuff there is between the big engines because after its all said and done the Buick seems to have been made the best all around. (For a powerful STREET ENGINE). IMHO. pdq67

 

I don't doubt the possibility of buicks being exceptional performers since they had a few awesome cars in the late 60's/ early 70's. GM made quite a few performance animals during that time from Pontiac with the 4OO to others more popular. I am saying that it should not come as a suprise to many crafters that the Caddi motor is so torquey.
