308 want more power

[Reaper]

A bad set of VN heads will still flow better than all but the best old style heads. There are plenty of them around - I'd start with ebay myself.

As for the rest - like any engine, HP is simple.

Compression - 10:1 is a nice compromise for street engines
Cam - Bigger is not always better however 10:1 compression should get reasonably large hydraulic cam to work
Heads - as mentioned above - VN style = win
Carburetter - I like Rochester carbs myself - shits over any Holley!
Intake - I have a TP dual plane manifold - excellent quality.
Ignition - Get the dizzy graphed to suit the cam/carb setup.

VN heads - $200
Intake - $900 (around that, apparently Torquepower is the one to go for...I'm using a shitty Procomp and so far it's actually been good...didn't even leak! Got it for $150 second hand)
Cam 2 suit EFI heads - $220 (I used a Crane Blueracer, from OG Speed Shop in Adelaide)
Crane anti-pump lifters - $145 (OG in Adelaide)
Extractors to suit VN heads in VB-VK - $600.

all of that ^^^ i wasnt really all that surprised when you hit the kw figure danny, was pretty dissappointed that i didnt follow that route from day 1. OP, VN's are the way to go and you should easily be able to do it with $2k.

DO IT

edit* just a thought too: you may want to consider fitting a couple of cats to the exhaust system too since none of the old pollution gear will work anymore.
