I'm running NGK R bp5's atm , I'll try 6's and see wat happens . I've got a modded 650dp on it , and its a c2 cast head but its been ported and chambers cc'd out to 55

Or as the smart ones say about time.Manuals are for cars without hp too make them interesting to drive.

OK your not gunna listen for what ever reason but I'll tell you anyway,actually pretend Im xrglenn for a while if it helps.
 
You can fit and use all this shit before you even do the engine so,buy a MSD Street fire Ignition for $179,get a TFI dizzy,and a good coil or a basic Bosch unit.That ignition system will now power any future combo you come up with.Ask Clint how well his TFI MSD combo worked out for him amongst others.Simple basic and the BEST thing you could do for any single combo you come up with as it will allow you make HP not limit HP like a electronic dizzy will.Why do I say this...because I have done it and have the results from all bar a crank trigger ignition and for the money I have to ask why not do it as all you will do is miss out on FREE HP.
 
Use no less than a 2.5 exhaust and get the collectors modified to enhance flow/scavenging.This again is totally free hp like the ignition and can be done to any engine in any state of tune at any time.
 
Buy a Romac or Powerbond balancer,I would and do use a custom Powerbond unit but as Glenn likes Romac use one of them if you wish.Again you can use this component on any engine at all at any time and it is FREE HP.
 
Next up buy and fit a DC electric water pump as it's FREE HP.I hope your getting the idea here by now.
 
After this is all fitted tested and made to work how you like start buying engine parts every week as needed.Buy 125lb dual springs,new retainers,locks to suit your stock valve gear will do for now.Any bigger and your into single groove territory.A gasket set to suit the intended rebuild,a camshaft and lifter kit after you consult with Camtech,sorry Crow in your case and do speak to them via the ph not just purchase something cheap off eBay FFS.I would advise you to ring Camtech and speak to Jim Tamborello aswell as they WILL help you.A set of bolt on roller rockers even 2nd hand of eBay if your that concerend about spending money on em will help.Scorpion do not make bolt adjustable's as I have a set on my ute engine and they need the head machined and a set of studs fitted that are just not needed here ATM.That said you don't need adjustable units here either,just roller rockers will free up HP aswell.
 
Then purchase your inlet,I cannot suggest a 4 barrel enough but if you want more throttle response and LESS HP and torque go for a 2 barrel manifold and carb combo.
 
If you buy it all as you go it will spread the $$$ out and allow you to spend a little more where it is needed.A car is a combination of parts so it will need a convertor and a set of gears to suit aswell so purchase with this in mind the whole time.
 
Thats me...

I hear ya bro...in a xflow RPM cost $$$ but they make torque in spades which in street cars means faster acceleration!Just got to mold em right...It's not super difficult just harder than and engine swap with zero add on's as you need a package.
 
I took my ute to Winton last year while it only revved to 6700 at the time it won all bar 1 of 12 races and only lost to a blown XR8 FG ute by less than a fender in the top end.It's all in the combination brah...that motor on street tyres in any gear would smoke the tyres till you got out of the throttle.Crazy tractor engine it was but while I short shifted in low gears I revved it out in top which shows RPM isn't everything but it also isn't cheap.  

Thanks mixalis im def excited :-)

You making your own bro is the only way.
