My 261 build and discussion thread!

Found a 56 261 early summer. Got it home and found out under all the crud it had a cracked water jacket from front to rear. Found another fresh 261 block that was on its original bore and already fully cleaned up in the hopes that its all good and has no cracks.

Already took the 848 head off the first 261 and had a shop clean it and check for cracks. Found out today all is good and its ready for machine work.

Any thoughts what i can do other than my list below or anything better i can do to it. Want it to be for a street build.

Here is my current wish list.

Head work:
- Mill face true
- larger intake valves (possibly from Tom L)
- New valve springs (already have new on hand)
- New exhaust valves
- Have brass valve guides installed
- Have the new style of valve stem seals installed
- Hardened valve seat installed
- Check and possibly port match the headers to the head exhaust openings if required.
- New rockers (Im actually missing 6 so I want a full new set)
- New rocker shafts (Im actually missing them also but have the perches)

Block work
- Bore block to .060
- Deck block as much as possible
- New pistons (not sure what to do)
- New rings (not sure what to do)
- Reuse connecting rods / pins
- Machine Crank
- Balance Crank
- Check and possibly replace oil Pump
- New Cam from Delta Camshaft (Same as what im using in my 235)
- New solid lifters
- New Pushrods
- New crank gear and aluminum timing gear
- Leave oil system stock as a bypass system and not go full flow.
- Stick with rope crank seals
- Timing cover bolt modification
- New water pump (old one is damaged)
- need new oil pan (old one has holes)
- Drill the crank for the pulley bolt

External Stuff
-Swap over as many parts form my 235 when its time to change over. Hei, dual intake, headers, pulleys, fuel pump, remote oil filter, and other stuff.
