Thanks for explaining sturdy. I couldn’t be assed. I did say a cam ‘with overlap’
I went with a 230/236 113. I’ve mitigated the inlet charge reversion with some itb’s and idle quality is excellent.
Yours is a 5.7 too right? I've opted to go for cubes to help tame the cam, stroking to 6.6 litres, upping the cam to a custom grind for the new heads, around 237/242 on a 113+2. It'll smell / sound fantastic I went with a 230/236 113. I’ve mitigated the inlet charge reversion with some itb’s and idle quality is excellent.

For him to map the car, you need efi live,a wideband and then make some data logs to send him. Mapping on the road is ok, for the drivability stuff, but you really want to do the full throttle stuff on a dyno ,if you value your licence.
There are plenty of places that can map a GM ecu now, Last map I got done in two hours of dyno time.
That said, if the car is stock,don't bother. Have a cam done, youll notice that
Hi Fred, totally O/T, but you dont happen to be the Fred Bloggs that runs a blown big block Tri 5 Chevy ?There are plenty of places that can map a GM ecu now, Last map I got done in two hours of dyno time.

Mines also a 5.7, I bought it running a vrx5 (236/238 .601/.605 113+2) plus vengeance racing heads etc, it just scrapes through emission level ( I have tested it) only time it smells is cold idle. It was mapped by rich ingram on efi live, she's lumpy but not bad at all to drive. And the sound as the revs build is amazing.
I mean, that's over 10* of overlap at 0.050, that's remarkable for it to pass an MOT emissions test, unless it's on some old test figure because it's come up unknown on the MOT system and is being tested as a pre-cat car It's a red 5.7 VXR isn't it? I remember it coming up for sale as the vrx5 is a cam I was considering back when I got my first cam

Yes a red 5.7 Vxr, got her in june. She's had quite a few mods, the list is on my profile. It's a nice motor. I've just been sorting a mild vibration at 50ish, had prop recon'd by d&f propshafts in leeds, swapped trans mount and now it's vibration free. Happy 👍It's a red 5.7 VXR isn't it?

[quote=SturdyHSV]It's different definitions of choppy idle.
A 'choppy' cam won't pass emissions because of the intake / exhaust being open at the same time, at idle this causes all sorts of exciting messy airflow and unburnt fuel out the back (hence the smell) and all sorts. Can also cause some bucking and surging under load at low rpm but unless it's an enormous cam most of that can be tuned out given time / skill.
The monkfish magic cams were around 220/224 ish (they varied over their lifetime with development), with a decently large LSA to keep the overlap down. They provide a good amount of torque across the range. They are MOT friendly and have good driveability, a small cam like that is very much a win win. They do have a 'different' idle, but not what some would consider 'choppy'
My first Monaro used an earlier Monkfish ‘magic 2’ cam which shook the car and was lumpy on tickover, so probably not what you’d call ‘choppy’. Monkfish did state that you may have trouble getting it through an MOT though, it also made 486.2hp on SRR after being mapped by Paul Spinks (and still going strong all these years later. I still talk to the new owner) My second Monaro, Bens old one, now Mezzells on here, apparently only made 470 with a Luis Sola tune/map so the old Monkfish ‘small’ cam would seem to make more power. Or maybe it’s just got a better map/tune as both engines were identical spec barring the earlier magic 2 cam in my first Monaro and a later cam in the second one.
