Thanks Sparky,
That is the length of the rods that were in the block. There isn't a whole set that are usable. I am looking at Howards I beam rods that are rated for over 1,000 HP. While on the same subject I have a better knowledge of the pin oilers you were telling me about. I'll be calling you before long to sharping the little knowledge I have about that.
Next week I'll be going to the IMIS trade show in Indy. I should come home totaly confused but I'll sift through all of it and have a good combo to go with.
The bore looks like it is 4.6250 with .009 piston clearance[on the old pistons]. These are rough measurements.
Stroke is 4.250.
Later,
Hooley
