so let me see if i understand this...

nba1341 · May 27th, 2007, 09:18 PM

these new engines now-a-days have 2 cam shafts?

wtf.......

HMUSN · May 27th, 2007, 09:19 PM

yup.

07 Grabber GT · May 27th, 2007, 09:30 PM

Along with 8 coils and 8 injectors. In order to make room they did away with the distributor and carburator. I had a 66 FB and was tired of tuning every Monday and Thursday to drive Fri thru Sun ... not to mention the burned valves and weak rings.

Now say it with me ... WTF

GTsetGO · May 27th, 2007, 10:36 PM

some of them actually have 4

Modern_Muscle · May 27th, 2007, 11:01 PM

03 04 cobras and machs have 4 cams...lsx has 1, 2 & 3v modulars have 2, 4vs have 4...

RStrick0352 · May 28th, 2007, 12:37 PM

Not to sound condescending, but do you no know the difference between an OHV overhead valve (the cam being in the block, above the crank actuating pushrods that actuate the rocker arms that actuate the valves), and an SOHC single overhead cam (one cam in each head actuating the cams, and DOHC dual or double overhead cam (2 cams in each head vice on, typically with a high valve per cylinder count). AND there are even "hybrids" where a SOHC will still have the cam in the block actuating either the intake or exhaust valves just like an OHV engine but still have overhead cams doin the other valves. There are even more variations on engine designs those are just the most common.

do you relize what you just said.
First off the mods are a Single over head cam and the 2,3,4 are the numbers of of valves per a cylinder not cams

RStrick0352 · May 28th, 2007, 04:47 PM

He was correct he just worded it a little ambiguously.

cams-shelbycobra07 · May 28th, 2007, 04:57 PM

cars dont have 4 cams 4valves yes but theres only one cam in the cobra and if im wrong then its 2

cams-shelbycobra07 · May 28th, 2007, 04:58 PM

o well everyone makes mistakes

RStrick0352 · May 28th, 2007, 05:04 PM

you are wrong, the cobra has 4 cams, 2 in each head. One cam operates the 2 intake valves in each cylinder and the other cam operates the 2 exhaust valves in each cylinder. Hence the Dual Over Head Cam, 4 total. Thats not all that crazy either, there is and Opel that has 6 valve per cylinder, and some other car whose manufacturer I cant remeber now has quadruple over head cams, thats right 4 cams per head 8 total in the car. Now thats amazing, imagine the size and complexity of that engine.

go to this website and read then youll understand

RStrick0352 · May 28th, 2007, 05:10 PM

OK, well that thread you posted only makes what I just said sound correct. What is it your confused about, I thought I explained myself pretty clearly. Just tell me and I'll try better to explain it.

RStrick0352 · May 28th, 2007, 05:12 PM

I know exactly how they work, I wouldnt have went into so much detail if they didnt. Thats just a generic picture and explanation. Good grief man I'm just trying to help you out.

HMUSN · May 28th, 2007, 05:31 PM

it's simple.

a Terminator.

4 cams total.

2 in each head

4 valves per cylinder.

8 cylinders.

which equals 32valve DOHC v8

cams-shelbycobra07 · May 28th, 2007, 05:33 PM

the way im understanding you you were saying for 4cams there is
DOHC meaning 2cams
And SOHC meaing a single cam
IM sure we both understand just not each other

HMUSN · May 28th, 2007, 05:36 PM

it's either a single cam per head or 2 cams per head.

(red lines represent camshafts)

cams-shelbycobra07 · May 28th, 2007, 05:36 PM

Ok never mind
