hi there

recently pulled the camshaft out of my hot 186 to find the camshaft saying CROW and 603 on the back. i looked this cam up on there site and it says its only a baby cam, like 443" lift or sumthin, but when i had this engine running it was pretty lumpy. is it possible that its a regrind??? im currently lookin for another cam for my torana xu1 when its finished and was looking at a camtech cam with 477" lift and around 291 duration. if this crow cam already in there is good enough i might just stick with it for a while to save some dough on new cam and lifters. does anybody else use this cam at the moment that can tell me what its like? or the rev range?

Cheers Blake

Hi Blake,
I have never used the 603 in a Red 6 but have used them in 308's before.
It is basically a performance hydraulic grind that I would imagine performing best between 2000 and 5000 rpm in a 186. Its no world beater or anything but for a daily driver it is a good size and would need a histall conv. or manual. Perfect for a weekender.

Hope this helps.

What's the significant duration like?

The cam ain't the only thing that can make a motor a pig down low lol

cheers struggler, and heath the duration is 214, i think this cam maybe too small for what i want or have anyways. my engine is basically xu1 spec with the triple 150 strombergs and big port head and so fourth. i was hoping for some real strong lump but something that has alot of 'go' aswell.

Cheers Blake

Okay, well yeah that timing isn't very aggressive... poor manifolding/carburation or even just bad ignition timing can give you some artificial 'lump' hehe

[blake]

ye it is pre small hey heath. and i presumed that it was probly lumpy due to poor timing, i thought this before, easily done hahaha.
i just want a big cam with lots of lump and "GO" but i spose i should settle for a mild type of cam while im on my P plates, hahaha.

For an XU1 spec engine with head-work and triples, I think the Crow 603 is definitely way too small.

I used to run a Crow 604 in a fairly worked 202 (226 duration @ 0.050, 2500-5800rpm, .423" lift). It went really good (it's rated as a 'High Performance street cam'), but I ended up upgrading to a slightly bigger Dynotech cam. With triple SU's, the thing was a weapon!

in the barossa region and i get my P's in january so ill be cruising soon in the 4 door lc we have if that doesnt sell, currently on ebay. but mainly focused on finishing my lc xu1 replica. also do you know of anywhere in adelaide that recurves dizzys? i know theres scorcher and there really good, but there interstate and i little bit more difficult. getting a dissy recurved to suit a bigger cam should help heaps along with my xu1 points i recently purchased. cheers guys
