284 or 276 cam for 5 litre?
Hey guys, just after info on a cam for my 5 litre.
Having a bit of trouble deciding on which cam I should put on my ute.
Pretty much my mates have swung me in the direction of the crane 276 and 284 cams. Problem is I dont know which one to get. Now to a Lil info on the small growing list of mods
3 inch cat back
K&n filter
Otr intake
Running 98 fuel
Oh and its a manual
Planning on putting 3.9s in the diff so dunno If that will help
Any help will be appricieted thanks

They seem ok but I think this camtech grind would work really well 222/222 112 LSA .511" .511BASIC RPM 1800-4500
Compucam H276
214/214 .464 .464
276/276
110 LSA
BASIC RPM 2200-5500
Compucam H284
222/222 .480 .480
284/284
112 LSA
it has the same duration as the 284 but more lift
Cheers. Will that cam effect my low end more than the 284 does ?

should be exactly the same even better with 3.9's
Yeah Righteo. Say if I didnt get diff gears just yet which cam would give better performance over the stock one
Right Foot Action
Doesn't really matter if you get diff gears or not. It just brings the cams powerband on quicker
What Gearbox A4 or M5?
Its an s pac so its got a m35 getrag -.- haha

So you'll need a clutch upgrade..... eventually
what series? cause if its series III its gonna change your cam options as its the later 'roller block'
Series 2 man. What bout the lifters. Coz crane cams do 3 options
Depends so much on what else you plan to do with the motor, and what you are using it for. Highway cruising, running kids to school or drag racing and speedway? There are heaps of different grinds to go for. Do it once and do it right. A lot of bigger cams need different diff ratios, higher compression ratios, stronger valve springs etc to be effective.
Crane cams now do roller lifters to fit into pre VT non-roller blocks, allowing you to consider the option of going with a roller cam (allows the cam to be more agressive in its shape, giving bigger valve lift with shorter duration).
Have a good look at Greenfoams cam selection thread, it is a sticky under V8 Development forum on Just Commodores.
Personally I have a Wade 963A961A10 in my 5L. Great fun for everyday driving and good fuel economy, but not suited to higher revs. Works well with the std intake manifold, std valve springs, std compression and torque converter.
Cheers for that one mate. I use it running to work and everyday driving. Do want it to be quicker but. How does ur cam go performance wise is ur 5l
Performance wise it is probably about the equivilent of a HSV 185i or maybe a little better. Goes from about 2000 RPM to 4500RPM very quickly and easily, but then the show is over. Still has plenty of low down torque, which is something that disappears as cams get bigger. I should add that I also have a full 2.5" twin exhaust, 70mm throttle body, K&N, CAI, Roller rockers, and a tune from Greenfoam.Originally Posted by satinblackv8
If I was to do it again, I would probably up the compression ratio by shaving the heads, put a dual plane intake and quad throttle body, bigger stall convertor, stronger valve springs and put in a more aggressive roller cam setup. But I'm just talking s*$%t now.
Haha as we all do when we think bout turning the 304 into a weapon

surely its gotta go better than that?? 185 is just intake/xhaust and ecu mods from factory
You won't need lifters but replace if your taking heads off!
Cheers for the help boys appreciate it !!!
