coln72 Posted December 17, 2009 Report Share Posted December 17, 2009 Compression, cam and exhaust will make a difference. With the cam, no need to go for solids unless you want to pull huge revs and like adjusting valve clearances. Ran a Wade 169 ground on the original cam and it was quite good.

seabiscuit Posted December 17, 2009 Report Share Posted December 17, 2009 I think you should spend your money on renewing your engines lifespan. It must need some serious maintenance if a 5k can't rev past 6400rpm. Even though mine is worked a bit, I can take it to 8000rpm (when it's tuned properly :n:). It obviously doesn't like it because it's not tuned right, but it still does it! Otherwise yea, best things to get done: Exhaust, compression, cam. If you've got some cash left over a head job would be the way to go. You can pick them up on the corner of the street pretty easily. :locked: In all of that, you're probably going to want to do at minimum a rings and bearings job too.

Doogs Posted December 17, 2009 Report Share Posted December 17, 2009 Everyone makes hydro lifters out to be a horrible thing, unless you are chasing large revs on a regular basis they are fine. Should you want high revs, anti-pump hydro lifters are also an option. If you are keeping things mild and on a budget I would say hydros are fine. Cam, headwork, exhaust and a reasonable carb setup should be plenty. Quote Link to comment Share on other sites More sharing options...
philbey Posted December 17, 2009 Report Share Posted December 17, 2009 Guys the reason your stock as a rock 4k 5k bangers feel like they're going to vibrate themselves to pieces is because they're not balanced. If you want it to rev had and smoothly you'll need a bottom end rebuild and balance. You can do all the other crap you want, but it'll still vibrate without one. I'm running Hydro's and some ridiculous duration mystery cam with way too much top end. Changing lifters won't net you more power and isn't the reason for it not revving at the moment. Get the cam grind to suit the lifters, run a bigger carb and extractors. Quote Link to comment Share on other sites More sharing options...
Duckman Posted December 18, 2009 Report Share Posted December 18, 2009 What would be considered a mild cam/carb combo for a 5K? Is going EFI a reasonable upgrade path of chasing some extra powah/kilowasps? Quote Link to comment Share on other sites More sharing options...

Beauc Posted December 18, 2009 Report Share Posted December 18, 2009 Shaun just put a commo v6 in the c**t, they are like < $500 and u can do all the nuts and shit u want all day long Need a better diff and a custom tail shaft and ur away (Well its not that easy but f@$k spending money on a K engine) Quote Link to comment Share on other sites More sharing options...

Whats the exact displacement of the new alloytec ones? They're a 3.6L engine. That said, there is a GC(or GD) Galant wagon rocking around NSW somewhere with a VP Commodore V6 in it. Looks like it was meant to be there. However, i think the Galant wagon tips the scales at 1000kg's or there abouts. Edit: Just googled the commowhore v6 displacement, 3564cc. So close!!!!!!!!!!!!!
