351 C Cleveland Cj 400 M Oil System Modification Kit:
Clevelands Rock!! I have built and raced them for over 20 years here in my shop. I have learned a few tricks over the years that will help them live. One of the tricks is this oiling system modification kit. It is one of the cheapest, easiest mods that you can do to your 351 C, 351 M or 400 to help it live longer, especially at higher engine speeds. Clevelands do not have the best oiling system, but it can be helped. The problem is that Clevelands oil the camshaft bearings first, and then the main bearings. The result of this is oil starved # 4 and 5 main and rod journals. My kit routes oil directly from the front of the block near the oil pump to the back of the block to force feed the # 4 and 5 main and rod journals and adequately oil them. It is a completely bolt on kit that you can install at home with simple hand tools. It will not hurt your engine, it will only help it. It will work on a new engine, or one with 100,000 miles on it. It will work with stock or high volume oil pumps. You can use your stock or aftermarket oil pressure gauges or both. I supply all the special fittings, 36" long stainless braided hose with 37degree fittings and a set of detailed instructions. It installs in less than an hour. I have successfully used this same kit on my own and on customers street, drag race and circle track cars for years. It works.
-The pictures on the block show black hose, but the kit is supplied with stainless braided hose.
