Requirements for a Miller OHV? I was able to run into a complete, good 1936 Miller Hi-Speed Head and I was wondering what the requirements are for the engine you put it on.
Are inserts recommended or is babbit okay? Which one will last the longest? Does it need full pressure oil or any other mods to the oiling system? I’ve never worked with overhead valve conversions before so I was wondering what exactly needs to be done to the engine in order to run one reliably and safely. |
Re: Requirements for a Miller OHV? I have a 1935 CRAGAR on a B engine. Babbit bearings and a counterweight crank. No pressurized oil or cooling. Engine has headers, FS ignition, Weber carb, V8 clutch and lightened flywheel. Everything has been dynamically balanced. Dyno run provided 59 HP at the rear wheels.

Re: Requirements for a Miller OHV? The best thing you can do with that head is send it to me! I'll sort all that out.;)

Re: Requirements for a Miller OHV? I agree with Dennis, babbitt is good, no pressure is needed unless you run much over 4,000 RPM's. I've run 153 MPH on babbitt, on the Bonneville Salt flats. If the Yapp 2-port has not been run before, I'd stay away from it. An engine builder in Whittier once told me that they take a lot of work before installing them. Check the Cragar carefully for cracks, they have a history of that but many are very good.

Re: Requirements for a Miller OHV? Charlie, The builder passed away several years ago, and the business was sold so can't contact him, sorry! He didn't go into any details with me. I have seen a few on the road, very few, in spite of the large numbers Yapp claims. Joe Sivils at Turlock Machine may be of some help, he builds some pretty good engines.
