TFX / AJPE Cast and Billet Aluminum | Oil pan rail on the windage side is moved out 1 inch to minimize damage with rod failure, also moved up to allow for more space to work. Oil gallery is between lifter bores to improve oiling over stock block ( it incorporated oil galleries with lifter bores) and supposedly an improvement over KB gallery on side of block that was inline with rod damage.

| This example has not been machined but note a water fitting on exterior of block
| A – tfx block is shorter and wider on bottom than original design B – Front gear drive is partially built in for increased strength front of block is longer C – starter pocket / optional ( but you can get around that problem . CLICK HERE ) | | The inside of this solid block has been partially machined to have a water jacket in the top part of sleeve area, it can be incorporated into a cooling system
| Gear drive is Partially built into block , basically a cover , gear shaft is supported in block itself. This is not interchangeable with other blocks ( RCD and TFX make gear drives )

ALWAYS CHECK PUSHROD AND LIFTER CLEARENCE IN THE BLOCK, EXTRA MACHINING FOR CLEARENCE MAY BE NEEDED IN SOME CASES. CLEAN ALL TAPPED HOLES THOROUGHLY. USE EXTREME CAUTION WHEN INSTALLING STUDS IN BLIND HOLES. EXCESSIVE AMOUNTS OF OIL MAY CAUSE A HYDRAULIC EFFECT AND RESULT IN DAMAGE TO THE BLOCK. THE A-1 H-11 STUD CAN BE VERIFIED BY THE PRESENCE OF THE .250 HEX INTERNAL WRENCHING SOCKET ON THE 9/16-18 END OF THE STUD. DO NOT WASH YOUR BLOCKS WITH WATER OR WATER BASED CLEANERS WITH THE MAIN CAPS INSTALLED ON THE BLOCK. AFTER WASHDOWN, DRY AND SPRAY STUDS WITH WD-40, JB-80 OR SOME RUST PREVENTATIVE OIL. IF THESE STUDS RUST WHILE IN A TORQUED CONDITION (TENSION), CHANCES ARE THEY WILL FAIL. TFX OIL RESTRICTORS-TFX-92-96-2000 THERE IS A 5/16 – 18 TAPPED HOLE IN THE DECK OVER THE # 4 CAM BEARING, THIS HOLE HAS A ¼ – 20 TAPPED HOLE BELOW IT TO ALLOW THE INSTALLTION OF RESTRICTOR JETS BELOW THE INTERSECTION OF THE .090 ANGLE DRILLED TRANSFER HOLE FOR OILING THE ROCKER ASSEMBLY.WHEN INSTALLING THE 5/16 – 18 SET SCREW USE LOCTITE AND RUN IT JUST PAST FLUSH WITH THE DECK SURFACE, IF YOU THREAD IT IN TO FAR THE .090 TRANSFER HOLE WILL BE BLOCKED.IT IS RECOMMENDED THAT A .045 RESTRICTOR IS INSTALLED ON THE EVEN CYLINDER BANK AND NO RESTRICTOR ON THE ODD CYLINDER BANK.YOU STILL MUST PUT THE 5/16-18 SET SCREW ON THE ODD CYLINDER BANK TO CAP THE OIL GALLEY OFF.THIS IS DUE TO THE CHARACTERISTICS OF THE TFX OILING SYSTEM. | AJPE 4 bolt Mains ( optional and can be retro fitted in some blocks ) | ![](http://darkside.ca/files/sites/default/files/5300.jpg) AJPE – 5300 5.3″ bore spacing |
