I just did a small run of PCV adapters to replace the road draft tube on your '49-62 331/365/390 Cadillac engines. In the kit, you get a black anodized aluminum bushing that fits into the stock Cadillac valley pan. Included is a grommet that accepts your 3/4” PCV of choice. Capping off the kit is a stainless bolt to fasten it via the stock rear valley cover hole. The kits are $65, plus $10 for UPS shipping in the US. If you're international, send me a PM and I'll find the best rate.
