Many years ago, a fellow Cadillac enthusiast took an open chamber head & sliced it up with a band-saw. This provided an excellent cut-away of the intake & exhaust ports for study & measuring purposes. He provided the slices to anyone that was interested, simply for the price of shipping.

I received one of those packages & now it is time to forward it to someone else who could benefit from the parts.

If interested, please send me a PM with your name & shipping address.

Thank you

Looking to get my 88 fox body project started. Iv seen the use of granatelli k members that need slight trimming. I believe I read some time ago that an aje fit without modification. If not is there a forum member that fabs cross members to get the engine bolted up. Thanks guys.

Hi Ron,

CaddyCarlo adapted that set-up. As far as donor parts & their identification, I'm sorry but I can't help you. CaddyCarlo has kind of dropped off the map for a while & I haven't heard from him lately.

Please check your PM box.

Thanks

Here is a posting on the various Cadillac Oil Pans & what they look like: http://caddy500.com/index.php?topic=611.msg10531#msg10531

I mis-communicated the info on the rear sump pan that I was describing. It comes from the 368c.i. powered Eldorado.


Good luck on your search

The 1977-1979 cadillacs are usually cheaper than the 472-500 cars. I need a transmission for my 500 project so I was considering buying a complete 425 car to obtain a a working turbo 400 and driveshaft, radiator, etc. That would leave me with a 425. Not really sure what to put in into. Possibly a truck. I put a 440 Dodge in a 91 Dakota but it was a tight fit. Its on youtube under "440 Dakota" its the blue one. Thats a good tip on the rear sump oil pan. Most trucks I have built require a rear sump. My plan is to put the 500 into a Ford Crown Victoria expolice car. I really like those cars ever since I drove them as taxis. The caprices are also nice. I like the Vics because they have four wheel disc brakes, modern four link rear suspension, 03+ has rack and pinion steering. The 8.8 rear axle might be able to handle the torque. Vics have a huge engine compartment to accomodate the 4.6 sohc motor. However those motors lack torque. They make up for it in high rpm power, but I think a 500 would be a much better engine for the 4000lbs Ford. Having the distributor in front makes engine swaps easier. I'll keep you posted on results. Thanks for the reply.

I've never messed with the 425. I would think that you could use the small chamber 472/500 heads on a 425, but you may have problems with too narrow a bore & valve shrouding. The 425 is supposed to be about 100 lbs. lighter than the 472/500 due to a thinner block casting, more lightning holes in the block & a much lighter crankshaft.

Nothing wrong with building a 425. Supposedly they out-rev the bigger Cads. The 368c.i. Eldorado oil pan is a real nice rear-sump pan. You will need both the oil pan & oil pick-up.

What do you plan to drop the engine into?

I say try it out & please let us know of the results.

Good luck

I now have a 1976 500 for my project. It seems that these projects always take longer than I planned. I have read that some people have put 425 heads on a 472-500 to raise the compression. I understand some say thats not a good idea. But I was wondering if the reverse is possible. Wouldnt early 472-500 heads give a small bump in compression on a 425 and flow better? I know you guys dont like the 425 and always say build the bigger engine. Is it possible? The 425s are cheap. Im a Dodge guy with alot of engine building experience with an eye toward the big caddys. The hot dodge setup is the 408. Its a 360(4" bore .030 oversize) with a 4" stroker crank. It seems that the 425 is all that and more stock 4.08x4.06. It seems to me it just needs compression, cam, and better heads, intake and exhaust. I am still working on the 500 drag race motor(got the cam, collecting parts) but I was considering a 425 as a street cruiser with maybe 375 hp and 480 torque. That would be 440 Dodge power numbers from a smaller engine. The big 440 torque beast only has a crank stroke of 3.75 in. Any input will help. Please dont say build a 472 or 500 because I already am

Here is a picture of the Cadillac T'stat.

I seem to recall being able to pick up a Stant 180 degree T'stat from Napa. I wouldn't run the 195 T'stat.

You can use whatever T'stat you want as long as you plug that internal cooling port.

Good luck
