just got in my 3.4 core engine,and a brand new set of aluminum heads.
anyways i have a few ?'s about the 3.4
#1 what are the stock cam specs
#2 the worked rods out of my 3.1 will drop right in right?
#3 is the 3.4 also rated to 7,000 rpms like the 2.8/3.1
#4 nothing to do with the motor but who makes really good clutches for the v6 cars im thinking about swaping the auto for a stick this time around but am a lil concerened about burning up clutches

this motor is going to get built for the rs and will be have the aluminum heads and be turbo charged of course

 

1. h260? i cant remember though, its been a long time since i looked at 660 cams. i think its a step below the h260, but not much.
2. yes
3. crank/rods yes, valvetrain i dont know.
4. i think centerforce makes some, dont know though, im far from needing a performance clutch at this point.

 

Centerforce makes a clutch for us, actually a couple of different types. The dualforce IIRC, is the best. Will give lots of holding power over stock and should be able to handle added horses and torque.

 

Duration: 195/201
I/E Lift: .263/.273
L/S: 109
IC: 111.5
Valve Lift: .394/.409
Rocker Ratio: 1.5

thats for a stock 3.4 cam

ive got the centerforce dual friction clutch. its pretty good, but if youre into 12s already, i doubt shes gonna hold up. i remember hearing of another company not too long ago, and i wanna say it was posted somewhere on here that makes one better than that.

 

thnx guys

hey drdave meant to ask u what paint did u use on ur taillights and were can u buy it at

 

on the other site I ***** at, the Spec 3 gets more positive reviews than the Centerforce duall friction.

 

can u get me mor einfo on this spec 3 clucth plz?

 

What you really need to do is invest in an entire clutch system that's not stock. You can get systems with really high hydrualic assist so that you can run super high pressure plate ratings and still have a feather-light pedal. That's how the new 'vette does it. Don't just think of upgrading the clitch itself, think about the entire system.

 

www.ultrarev.com will get you the best deal around on a spec clutch for our cars. i got one, its a nice peice

 

wow thnx redbird
those clutches are perfect !!!! now to see if i can build up a manual 5 speed to hold up to the abuse before i make my choice on wether or not to do the trans swap along with the new motor

 

hey redbird which spec clucth do u have?

 

thats the clutch i was talking about.

the paint is Testors transparent candy apple red. i bought a small spray can. when i tried to separate the lens from the housing, it broke without hardly trying at all. what i found works great is some heat. i put mine in a paint booth when we baked a paint job at 180 degrees for like a half hour. as soon as i pulled it out i separated it, it came apart so much easier, still gotta be really gentle w/ it though.

 

thnx drdave.ive tried looking for that paint but cant find it anywere.
-----------------------------------------------------------------------------
the 3,4 comes apart this week to get cleaned and diped.then im gonna bore it slightly oversize and get the custom pistions ordered so ill have 8.5-1 cr ratio with the aluminum heads

 

i got it at meijers. or check a craft and hobbie store that sells model cars. theyve gotta carry it.

 

i got the stage 3, cause i feel like snapping my trans in two...well, the stock one i had didnt like slip launches and then power shifting into 2nd, ON MY 2.8! i didnt get the posi unit yet because i dont have cash to get a new trans , i might want that 700r4/converter u got

 

daves12secV6, please tell me you're going to get teh piston crowns, combustion chambers, & valve faces thermal coated.

 

let me say just one thing, youre crazy, you get this stuff done so fast! there is such a thing called sleep, you should try it sometime.

 

naw only reason im sorta rushing this build is cause aug 20TH is the f-body nationals @ island dragway,and im hoping to get this finished so i can cause some havok in the heads up classes,no v6 car has ever run in the heads up classes before,if i can get down to mid 11 sec times i could go a few rounds in the radial tire heads up class,or possiblt win and really turn some heads doing it .

right now the plans are to build the 3.4 with ported aluminum heads,custom crank/rods/pistions and boost the hell out of it(getting a massive t-70 turbo),and spray the 35 shot to spool the turbo


but if that dosent work out ill have to run the 3.1 with the iron heads,which i dont think the crank/rods can take much more power,to be competive with the iron headed 3.1 id have to lose about 500-600 pounds out of the car,and spray at min a 50-75 shot
