OST-053: Massaging a 20V Blacktop

[oldeskewltoy]

Well... it has been forever... (well it feels like it).... and it no longer feels like a massage....

A new crank, a new set of rods(Molnar 42/20).... new custom (dome) pistons (11.5:1).....and MRP oil pan.... and the 20V Poncams are currently not available


We needed a crank, the first one we bought used... found out all the journals were a few ten thousandths (.000_") too thin... it might have worked for a dry sump race build... but for this engine my client (with my advice) bought a new crank.

The TRD rods (Jorge, your machinist has a good eye...) There was a dodgy bushing in one of the rods... to fix it properly would have required making the small end too thin... so the TRD rods got canned, and a set of Molnars were ordered.

JE Piston has a 11.5:1 piston.....



but... that ratio is with an .040" squish, our target is .032-.035, so I asked them to reduce the domes from 6.5cc, down to 4.2cc.





As far as oil supply, we decided a set of Toda pump gears, and an MRP pan





The Poncams....?????????? They've been delayed twice now... Tomei, and Kelford seem to be out of blanks.... and while Cat cams appear to have blanks, I'm not a fan of the Cat cams 20V cam timing.....


The head is ready for re-assembly.........




more to come....
