 Posted: Sun Jan 28, 2007 9:35 pm Post subject: Heads & Cam (Dyno Pg 12 & 27, 1/4mile Pg 18) |
 |
|
Alright so ive finally got the cash to go out and spend up abit on the ute. Was thinking stroker but budget is pushing me towards a nice set of alloy heads, cam, roller rockers, intake, 24lb injectors, 75mm MAF, 65/70mm t/b and a tweecer or CAPA chip.
Havent quite decided on a head/cam combo yet, I have a fair idea but nothing is certain yet. Thats why im here so you guys can help me out.
I think i'll start off with the questions bout the heads. Also i will be buying the heads complete with valves & springs etc.
Firstly i was looking at the AFR 165cc heads but am unsure if i have to go for the emissions legal ones or not due to the fact my EGR set up is all blanked off.
Also would i go for the 58cc with stud mount, 60cc with pedastal mount or 61cc with stud mount. Alot of the cams i have looked at suit 58cc combustion chambers.
Would valve springs need to be upgraded?
These can be had for around $2300 complete
Also lookin at Edelbrock Performer heads. Unsure wether i need the 1.90 int' valve or 2.02 int' valve.
Both of these heads have 60cc comb' chamber and 170cc intake port.
Would valve springs need to be upgraded?
These can be had for around $2100 complete
Other heads i was lookin at were the Trickflow twisted wedge heads.
These only come with the 2.02 int' valve, 61cc comb' chamber and 170cc intake port.
Would valve springs need to be upgraded?
Unsure on price with these but wouldnt be suprised with between $2400-2800 complete.
Basically looking for a decent head that will bolt straight on. Would rather avoid having to notch pistons but if it needs to be done i'll do it.
Was thinking work out which head im going with then choose a cam to suit, is this how i should go about it?
If you can give me your experiences/reccomendations/thoughts on the above heads and other questions that would be great.
Also would be appreciated if you guys could help me through this process, i'll try make it as easy for yas as possible  .
Next step will be deciding cam/rocker combo.
Cheers guys
Jeff

Heads - whatever you can afford really. If you can afford them for a 5.0L AFR165s will be the best for a street car but expensive. Custom cam based on the overall package which should come with valve springs. Valve springs should match the cam you are getting.
For more information go to www.corral.net |

yeh custom cam be the go. i went with a Comp grind, but coz of recent stories about distributor gear incompatibilities, go for someone else.
i went for afr #1472 heads.(165cc, ped mount) rockers cheap/easy to fit. and my egr circuit is blanked off, so getting the emissions heads meant nothing changed from stock anyway. |

Cheers for the replies clampy. i have an Edelbrock Performer RPM intake sittin in the shed i bought a while ago. A guy over east was selling for a good price so i thought i'd snap it up while i could. If i had a choice i would have gone the normal performer not the rpm. I thought i may aswell throw it on with the new heads etc and sell the explorer. Or if it isnt the best way to go about it i might have to sell the edelbrock and keep the explorer.
What do you think? |

how much power u lookin to put out? coz depending on that, the explorer could be perfect, or rob top end power.. or the rpm could be perfect, or rob low-mid range torque.
i stuck with my gt40 tubular, coz even if im losin 20hp up high, that extra torque is gonna get used alot more on the street. in my opinion 20hp over a 1500rpm spread aint as good as 20ft/lb over a 3000rpm spread |

| Not all is lost with the RPM. Shares the same lower with the Performer (which I would also go for) so when you have the rest of the motor done, you can swap the upper intakes and see which tickles your fancy. I think the performer will have a flatter torque curve which is what you want in a street engine. |

Would be happy with 200rwkw, but more concerned about havin a nice flat torque curve. Not really too worried about peak power, i mean a high figure would be nice but just not what im concentrating on.
So anyone want to buy a performer RPM inlet manifold, or swap RPM upper for performer upper? |

One Drone do you think the low-mid range torque difference between the explorer and Performer RPM would be noticeable? |

i still run the xplorer setup with svo heads and a decent cam. mine also runs a fair bit of compression too.
mine breaks traction on acceleration in first and second if that helps |

Cheers for the link mate, an awesome read that was. Exactly what i wanted to know.
You know anyone who wants to buy a Performer RPM inlet manifold?

I'd say theres plenty of cams that will suit the manifold, but they would probably all be cams for high rpm to work where the manifold does its job.
Personally i want lotsa torque around about 1500-3500rpm.
Looks like there could be two blokes wantin to swap upper plenums. |

Im guessing the big secret would be the cam. Basically just your engine combo minus what you dont want to let out, even driveline info would be interesting to see. Dont worry i also want to go with a combo thats a bit different from everyone elses but just want to make sure ive gathered enough info/advice on everything before i go out and buy all the parts, chuck em all on and end up dissapointed. |

also the heads you're looking at will be either trickflow or inlines with 1.9" valves.. so a cam to suit the rpm would want high revs and high flowing heads. it wont get either(heads wont flow all that much with the exception of the tf tws but factory donk limited at 6250rpm anyway, and heavy hyd roller drivetrain prob shuldnt rev much more than that anyway).. so ull end up with not much more power than a 'smaller' combo, except with a good smack less low and mid range torque.
give it a month(so i can finish stuff), ill let you know what AFR165s and a port matched gt40 style intake will do. both on dyno and quarter mile. my cam is in the thread i mentioned earlier.
XH, i understand you not wanting to not go the same as everyone else. i went the comp cam but every man and his dog seems to get the crane 20xx's around here(im sure its a good cam also). plus afr 165s not all that common. that said, i picked that combo because of so much evidence of great power and torque coming from mustangs with those same parts. www.corral.net is great. |

| lastly, XH where did you get the 2300 afr165 price? coz i got that price also except thats with a lead time of at least a month. at the time(two months ago) i couldnt wait that long so i paid a bit more than that. |

That price was from A1Hiperformance in myaree from their website. I havent actually rang up and got firm prices yet, just lookin at approximates while i decide which head. Where did you source yours from? |
