the 150A and 392C are both magic camshafts, nice lump, good power but the 150A isnt that much of a pig.

It's ok, idles well with a bit of a lump in it, performance is notably better than stock, you can tell when it "comes on cam" and drivability is fine with a 5 speed box.
In all honesty, I'd prefer a bigger one. I reckon a 40/80 would be a good thing, if not slightly bigger again.
Just make sure your bottom end will handle at least 7000rpm.

Stage 5 Heatseeker
biggest hydraulic one they made for holden 6. solid went to stage 6
was a bit of a pig to drive
Incorrect as Heatseeker do the HS60 hydraulic still and it is a stage 6 plus Peter still grinds custom cams to suit what ever info you give him.

Thinking they are somewhere on the NSW north coast now.
There old 30/70 cam was the ducks guts for daily drivers.
Reckon they forgotten more about red 6s than most these days know.

sorry to jack the thread but while where on the subject anyone no the best cam for 186/stroker 221 crank, As far as i kno there not good for high revs so anything revn over 6 is no good. Place i spoke to about puttin motor back together recommended crow xu1 cam but ive heard a few bad things about them plus wots the point of having a cam in there thats needs to rev more than me motor can handle??
more cubes will put the rev range lower on the stroker than it would on a 202 or 186.
so the rpm range will be lower than all the listings for cams that are for a 202.

My experience with Strokers is limited But I do know a bit about the 235 version. It is true they don�t like big revs. 5800 would the limit. But what they lack in high rpm HP they make up with in the way of torque. Crow aren�t that bad. A bad batch of cores can haunt any cam manufacturer. I would pick a cam with 6000rpm limit in mind. You also want a fairly wide lobe separation. This spreads the power band wide to make use of the torque offered by the extra cubes. I�d use a crow 35667 cam. We have installed this cam in a 186 daily driver with one of our new SIM002 EFI Intakes. It idles well and makes power between 2500-6000. The 100 lobe separation and the high lift both help improve the cylinder filling. Cylinder filling in emphasised with the extra cubes you have. A 72 XU1 cam only has a rev range of 2500-5800, but because it relies on duration rather than lift to fill the cylinders I feel the 35667 will offer better performance in your application. I hope this info helps
this is info i got from a fella who makes main stud girdles, anyone no of a really really good holden 6 engine builder in adelaide?
