It's actually a 496.... #cubicinchesmatter
Weighed and measured the pistons/pins today and filed the piston rings.
These are Diamond custom pistons with Trend wrist pins. Rings are Total Seal .043/.043/3mm with a Napier 2nd.
This will probably be about it for a little while. Heads should ship on the 29th and then I can get those assembled. Crankshaft is backordered until January.
