1st Time Caddy Build

Post by AirPat » Fri May 01, 2009 9:20 am

I am finally picking my motor up from the machine shop today after a long wait. I am going to start to assemble the motor tomorrow. I have never built a motor before so I am looking for any pointers you guys have. I have bought about every book there is to buy on this motor and have read countless post on here about the cad motor. Here is a short run down of what I have:
Motor was a 472.
New 500 crank ground and polished.
.30 over
New Potter DD cam and springs
Silvia (sp??) pistons
New valves
Cloyes chain
New edlebrock intake
All machine work done.
Basically the only parts I kept from the original motor was the piston rods and the push rods. I know I am leaving things out. Looking for some pointers if anyone has any. The boat is a 15X8 fiberglass DD.

This is a tough engine for your first build because they are unforgiving on tolerances. IGNORE the factory tolerances for this use. Your crankshaft main bearings need to be at least .001 oer inch of bearing or .00325. The rod side clearances MUST be at least 25 thousands if not 30. Mine are 35 in some of my engines. If the clearances are less, return the engine to the machine shop and get it done right. Your Silvolite pistons should be fine, as will the stock rods. Use the ARP bolts! and you MUST have the rods resized if you use these bolts. Use a FACTORY aluminum oil pump, NOT the mellings pumps--they are junk. Feel free to call me for help as you go--you will thank yourslef for spending two extra weeks doing this right rather than burning it up and starting over...Charles (954) 444-three 189

Do not drive your crank timming gear with a hammer.

I have learned that Ruagtr has forgotten more about Caddy motors than most know. He is a wealth of knowledge. If he says it, count on it. He and Bondsman are most generous with accurate information. Having the sense enough to listen can be a challenge for some. Both have been exceptional resources for my build that is almost done.

I appreciate all the info. I was unable to start the build becuase the rod bearings I recieved with the crank are damaged. The company is sending over another set.
James,
The gaskets are Fellpro. I am not sure what you are talking about on the cam. I had the machine shop call Potter for any special instructions and he said I should be fine. The valves are one piece. The heads are 76cc. Rings and bearings are from Federal Mogal ? I bought a kit with all the parts and this is what it said on the box.

Ruagatr,
Thank you for the offer. I am sure I will take you up on it.

Thanks again,
Pat
