rebuild vs ecotec

[Hearnie_bra]

Gday guys bought a full l67 s/c set up for my vs commodore and decided to buy a seccond hand l36 motor and strip it down and rebuild it, just want to know what sort of parts i should be looking at to build a stong motor thats capable of making some good hp at the treads cheers

 

[Wombles]

To suit L67 top?

 

[Hearnie_bra]

Yeah mate, got the block fully stripped down now

 

[Wombles]

Get the L67 pistons and con rods.
Forge pistons will be best. Cam to suit L67.
Just strengthen the crap out of it.

i can get the l67 pistons and rods just gotta get them out the old motor, what other parts would i need to strengthen it? going to get a double row timing chain and a decent cam.. cheers

Get the ridge removed in the rods. Its called shot peened and ________.
Supposibly that strengthens the rod.
Ensure everything is balanced!
Talk to an engine builder or Steve feom Mace. Both will hit you up with great indo.

If you want a bulletproof build get:
+ Forged pistons (JE's / Diamond)
+ Powdered rods or Forged H rods (Forged are lighter and if u get em with the ARP 2000 series bolts, they should be good for 1000HP assuming the rods are good).
+ New old crank if you come across anyone selling these (Better than machining a 2nd hand one because you loose strength in the crank depending on how much is machined down)
+ Balance the whole bottomend (Flywheel, Crank, Rods, Harmonic balancer)

If you're on a budget you can re-use the L67 rods (They're actually pretty strong) and get a new set of pistons.
People have been getting ~300+kw from absolutely stock bottom ends in the states.

I'm doing a complete build. Good luck with yours.
