Had to work on a set of brodix BB3 heads as well last week. The insert from Martin Wimberly for surfacing and a new valve job insert from Chad Speier works great on the Bridgeport Mill.

Well haven't posted in a while trying to catch up on all the projects in the shop. But here is a quick summary.

Got the 605cid HEMI complete and on the dyno this week. For a pump gas deal I am pretty happy with the results. made 750HP at 6100RPm and 700ft-lbs at 5200RPM. Torque was flat from 4000 to 6200 and over 650ft-lbs for the whole RPM range.

Also got the 496cid with 8/71 blower done as well and shipped.

Now on the dock I have:
- twin marine 468cid,
- 555cid mud truck
- 720cid mud drag
- 632cid mud truck with major improvements
- still finishing the 706cid 14/71 blower.
- 434cid 18* small block for a change to an aluminum block.

The grind never stop!!

Starting on the next project. Pair of twin 468cid for a marine application. Will change cam/valvetrain/pistons and put my valve job on cast iron heads with some chamber work and minor port work.

Still many projects ongoing waiting either on parts or machining work. And more waiting for their turn in assembly.

After a couple of months of preparation and parts ordering its finally time to start putting this beast together. This will be a 706cid with a 14-71 TBS blower and holley EFI system for a show car. Intake is getting plumbed for Nitrous as well!!!!

Got the BRODIX Cylinder Heads block all blueprinted and the Callies Performance Products crank and rods attached to Diamond Pistons custom pistons. Custom cam from Bullet Racing Cams is all in and timing set with the Jesel Valvetrain Innovation belt drive. Bottom end is using Moroso Performance Products, Inc. 2 pieces oil pan and external oil pump.

Next up will be to get the Dart 20* assembled and installed and valvetrain finalized ready for the intake and then wr can finish the top and put fire into it.
