  • When I took off one of the Main Caps the Dowell Pin moved. I was quite taken aback. I have never seen a Dowell Pin actually loose. Well that also tells me something.

  • The Main Bearings tell you the horror story and the rest of the block tells you the story of holding up to extreme friction. The trick is to read the picture for about thirty minutes so you get the whole story.

  • I have never seen the freeze plugs installed with Never Seaze. Or perhaps is was Sensor Safe Grey RTV. I was not quite sure. I like to utilize a special adhesive and corrosion preventive on the Bronze Freeze Plugs that we use.

  • Here you can see the worn our Lifter Bores. They are not just worn they are whored out. I have not seen a set this worn yet. I will have to bore them out and install an oversize lifter to compensate. There is no other way. The only other option is...

  • In the case of the Piston Bores I can allways Sleeve them. In the case of the Lifter Bores I cannot sleeve them in Bronze Liners. Pontiac lifter bores are quite thin. I can always install Cast Iron Sleeves and significantly undersize the O.D. of the...

  • Some people like the OEM Rods. In this case I will pick an OEM perfect set. Usually out of a 326 or a 350. The set to pick must have low miles, no spun rod bearings and the Big End of the Rod must be in spec for me to perform this Reconditioning.

  • I must admit I like polishing rods. It is just cool. I hold the Connecting Rod in my hand and let it tell me just where to remove the bad metal. Then when I am done they look like a work of art.
