4k Head – Has to be Flat piston head
5k Block – Has to be dished piston block, how to spot a dished piston block it has no welsh plugs along the cam journals as well as the displacement (1486cc) cast just below the deck height.
2 Types of Dished pistons in 5k
"O-dish" - around 6-8cc - The O-dish 5K had no lugs. Virtually identical to a 4K head, smaller ports.
"D-dish" - around 22cc - The D-dish 5K had the lugs on the head and slightly bigger ports.
4k Head with 5k block will decrease compression to 8.2:1
Running 8psi of boost compression will be around 12.4
Lighting Flywheel to around 4kg-5kg
Balance crank, pulley, flywheel, rods and pistons
See if I can use a Gilmore belt from a 4k aircon for the supercharger
Still haven’t found dimensions info of the pulleys, some info would be grand..
Camshaft – 112@40 grind 4k solid cam - kickn5k :y:
Extractors – Whatever pops up, been looking at the coby extractors on Trade me
Carbs - Maybe a 32/36 or twin 40, Depends on budget ( need more researching in this )
Fuel pump needs to be running more than double the pressure going through the Sc
Other info
Use 4k Head bolts Stronger Thread
Use some grease on the head bolts if not torque numbers will be incorrect if not.
Info I'm chassing
- Where to buy a full 5k gasket kit ( needs to be strong like Russia )
- Pulley Dimensions
- Carbs
Thats all for now
Cheers :wink:
