Cadillac 331-365-390 Stainless Steel Hex Bolt Kit
The image above shows the majority of the parts we ship in our kit.

THIS IS THE LARGEST KIT ON THE INTERNET FOR THIS ENGINE.


Dress up your Vintage Cadillac V-8 engine with our stainless steel hex bolt kit!! This kit has a natural stainless finish. It is NOT our polished kit. This kit has all standard hex bolts and does not contain the indented hex bolts shown in the picture of our polished original style kit.
 
These are the finest stainless steel bolt kits available. Alloy Boltz is the largest stainless kit seller on Ebay. We also offer 304 Stainless Allen kits and grade 8 stainless ARP kits for more applications than anyone.
 
This Cadillac bolt kit fits 331, 365, and 390 engines from 1949 through 1962.  Due to all the different water pumps over those years, you will have extra fasteners.

This is a complete high quality stainless steel hex bolt kit. The kit includes individually packaged and labeled component kits for the following:
Intake Manifold
Timing Cover
Water Pump
Oil Pan
Oil Filler
Ground Straps
Thermostat Housing
Distributor
Coil Bracket
Fuel Pump
Valve Covers

If your engine has aftermarket components, let us know so we can send longer bolts for Aluminum components.


Our washers are custom made in the USA to our specifications. Alloy Boltz uses larger diameter and thicker flat washers in our kits.

Our flat washers give more support to your engine components. We also add split lock washers on some of the component kits to make sure things stay tight. 


The thin small diameter washers other sellers use offer almost no support and will cause your valve cover or oil pan rails to bend.  If this occurs, the gasket will pinch and you will have oil leaks.

  

All of our washers are polished to make sure your finished project looks great!

 

We use our extra thick intake washers in this kit. These washers are thicker and have a smaller center hole to keep the washer centered on the bolt. Our washers are specially made for us in the USA to our specs.
