rocker arms

[stykthyn]

I am building a 3.4 for my suv, what are good rocker arms to use? I really dont want to keep stock.

RE: rocker arms

Which 3.4 are you using? RWD iron head or FWD aluminum? I believe the Crane gold race rockers will bolt on either one, or you can do like I did and use SBC roller rockers, but you have to get the ARP rocker studs with the 10mm bottom thread and 3/8" top thread. Also, the SBC rockers may need to be checked for clearances with the intake manifold, and valve covers.

^ quite a few rocker arms for the iron heads

The Cranes are the top of the line. I use them and love them. They are pricey though.

if you want a bigger ratio for cheap you can even go with '93-'95 3100 rockers. they are 1.6 ratio.

[geoffinbc]

Um 93-95 rockers on 3100's are 1.5 ratio are they not?

Yes they are.

No, they are 1.6 ratio. I got that info direct from GM Powertrain. I always thought that they were 1.5 as well, but my guy at GM confirmed that they are in fact 1.6.

If thats the case, I have some sitting here at my place, for dirt cheap.

[no1kicker]

Slick, sent you a PM about the rockers.

Really? Hmm.. interesting.

[gpse3400]

yeah the are 1.6. My '93 3100 manual says plus you can compare the pushrod seats with th eolder ones. definalty 1.6.

[Scott_68B]

Sorry if this has been addressed before but would it be possible to use the 93-95 3100 1.6 rockers in a GEN II motor? If so, would new pushrods be needed as well?

Thanks!

Yup just plop them in.I gurentee you'll feel somthing from it. Also if you cant swing getting a chip, Get fuel injectors from a 3300 V6. I gurentee those two togther will make the engine happier.
