Heres a cam idea for the DOHC

[your_I.D.]

How do you plan on timing it?

Q

Going to take time, a lever type dial indicator or plunger type with a modified adapter tip (to clear cams) a degree wheel and knowledge of cam timing to crankshaft degrees. Since the cam timing flats will only be useable to time the exhaust side. Once accurate degree's are determined. It will be simple to do. All that will be needed is a cam timing tool for one cam and a degree wheel. Time exhaust cam. Then hold the intake cam and rotate crank to required degree's lock down the cam. Then move to the other bank. Rotate engine to time exhaust cam then hold intake and rotate crankshaft required degrees.

Heres a link that will explain cam timing in degrees.http://www.iskycams.com/pdfcatalog/2004-05/page205.pdf

what about getting 2 pairs of quad 4 HO cams,then cutting them down to the 3.4's cams length?
I'm sure thats completly crazy tho.. hehe:P

Crazy, yes. Impossible... well FUCK YEA.

the lobes are set at 90 degree intervals, the 3.4 dohc's are set at 120 degree intervals. Also the cylender spacing on the 3.4 DOHC are about 3/4" more then on the Quad 4 so the lobes are also 3/4" further apart. ALSO, the Quad 4 cam journals are just over an inch wide. while the 3.4 DOHC's are approximatly 2" wide. So you would have to add alot of metal.

You MAY have won todays dumbest, most least thaught out: "you have got to be fucking kidding me!" post of the day. Thanks, I needed a good laugh, I know you were joking. (or at least I hope)

Since there is about a zero percent chance of that plan working, it gives me one stupid, but not all that impossible idea... Take the Quad 4 cams on a lathe, cut the cam before each lobe, then machine a 1" hole through the center of the lobe (easy work for a lathe) then cut the lobe off, and carefully TIG weld them all onto a piece of 1" steel bar stock. and put roller bearings between each lobe pair to support the cam in the housing... not impossible, just highly impractical. like putting the DOHC's heads on the aluminum block.

I think Im going to make a stupid post in the quad 4 forum for shits and giggles, look for it when you get a chance !

here, have a laugh it was actually quite difficult to misspell so many words and forget almost all the punctuation. I might have tried too hard though. Its obviously a joke I hope.

heres to one of my stupid q's lightening someones mood

well I wasn't joking,but I didn't expect it to work(I figured the bearings would be diferent... I didn't even think of spaceing )

I do have a solution to the cam timing problem with two exhaust cams. If the flat that is on the cam is well out of the way, you could possibly TIG weld on a piece of steel to use as a new flat, but placment and height of that piece you weld on is crucial for a proper timing of the "0" degree point of the cams. The stock intake cams are probably your best bet for finding that zero point. I still would like to know if the intake and exhaust cams are any different, and if so how much.

According to spec. listed on main page:

Lobe Lift (Intake)
0.370 @ 108° Crank ATDC

Lobe Lift (Exhaust)
0.370 @ 115° Crank BTDC

Wont work. exhaust cam is missing a key feature.........

No casted lug for cam sensor to pickup off of.

[BlueShift]

It'll work if you're running the 91-93 MAP type system. That's the route I'm going on my Fiero engine swap right now with a 91' Olds Cutlass motor.

[donk_316]

yeah not using the cam sensor. using a 7730 to run this unit.

[your_I.D.]

ok then it will physicaly work. Just need to figure out timing issue.

[donk_316]

Honestly im not worried about any "timing" issues. Im just replacing the INT cam with the more agressive EXH cam. then adj for power with the pulleys on the dyno

[your_I.D.]

You cant use the timing flats to set intake(really an exhaust cam) you'll end up with 4 valves opening on the exhaust stroke.

[donk_316]

???

maybe im thinking of something esle than you are...

Ill time the new intake cam to where i want it. the 4 valves arent going to open at the same time if the cam is phased with the original position of the int

[your_I.D.]

Right, but there will be no way to use the timing flat to set. It will have to be done by degreeing the intake cam. Or guessing.
