Hi there,
I was wondering if anyone knows of any companys that make an adaptor that allows 500cid cadillac valve covers to fit a 365 v8 cadillac motor.

I know nothing about Caddy engines so bear with me. Why do you want to adapt the valve covers? Nostalgia look? Service features? Are you aware of any engines with that conversion or is it something you conceived? Can you post pictures of them and point out the incompatibilities?

Since the 365 wasn't around for very long no one made valve covers that fitted the look I wanted. I was looking for a finned variety like the old corvette style. I have found a number for the big block caddilac which is why I was wondering if there was an adaptor.

I have seen adaptors for SBC center bolt to side bolt valve covers. I did contact a company in the sates as I am in the UK and they have come back with come back with a pair of new alloy OFFY valve covers that fit.

I suppose I could fit a 500cid Cadillac mill for the valve covers but I am having problems justifying it to the wife :-) .

I'm afraid you are on your own on that one. There is an infinite variety of that kind of stuff for the SBC, but a not very popular engine like the Caddy 365 will have very few after market parts. Are the 500 covers the same length and width as the 365? Is it just the mounting systems that differ? If so, adapting them should be possible. Got pictures & dimensions? How about adapting Chevy 350 finned valve covers? Seems the two engines being the same displacement may have the same valve cover sizes.

Offenhauser still makes a finned valve cover for a 365. I just bought a set.

Moom equipment also sells a set, finned MP644-$215.00

I'm getting an education here.

These?


These?

Looks like it is easier to get 365 vintage valve covers than it is to get ones for the 500. Here is a guy who makes adapters to mount 365 valve covers on 500s!

I tell you what this place still amazes me and I eat humble pie every time I post something on the BBS.

As with all things the valve covers debate started when I decided to change the carb on the car. Where the carb was leaking on the manifold it looked so bad I had the manifold Jet-Hot coated in the sterling finish. I got talking to my brother who loves all things polished and we sarted the hunt for finned valve covers, this is where the 500 adaptor idea came from. So here we are today more covers for the 365 than the 500 and another happy customer.

Next is a set of ARP polished stainless bolts for the intake to finish it off.



Thanks for all the info

You need to go to donshotrodplace.com and go to projects, he is doing all kinds of stuff to a 57 cad, including installing a big block cad engine. However you must be aware the steering box is in a bad location for a big block and ends up with your exhaust manifold touching it, no clearance. I'm using a LS7 427 small block in mine. Brian

I bought 472/500 covers, then I got set of 365 covers. Keep the 472/500 covers. I had to cut on top of the 365, then when of the 4 ribs to the cadillac and the other side to tack with welding as easy tacks and clean the tacks. I used a epoxy with that glue that you would mix in a gun to seal the gaps. Then clean with a da.
I did that on my 40 ford coupe, the covers on the 365 are longer, so you have to cut on the cadillac on shorten about a 1/4" on front and back.
It is great.
