I want to do the 3.4 swap, and would like to know if compcams or crane roller rockers fit the 3.4. Or any other sugestions for mods, it would be nice to do it before i put the engine in. i found a 3.4 in the junk yard with 76,000 miles on it, just have to come up with a price for it, anyone know what its worth? i read ked85s post on the swap boogie and i'm ready to go for it, thanks

Yes, they both will fit (cam and rockers)

thanks, when i was looking at there sites they list 2.8 to 3.1, then the rocker arm studs are metric on a 3.4? what i want to do, if i can is put 1.6 rockers on it, i don't know if there will be enought spring travel with the stock valve springs, anyone try this?

One of my friends put 1.6 rockers on his 94 camaro 3.4, had no problems.

I paid $800 for my 40K motor.
That motor is due for a rebuild, real soon.
Let that guide you.
IF you take it, rebuild the heads.
New valve guides will do wonders.
Bottom end, you may get away with no problems, depending on how hard you beat on it.
Reality.
Lotta work for "that" motor.
Keep looking.
The "idea" is to spend the effort (swap), without doing a rebuild (of 3.4 running engine), too!

(quiet voice in the corner) just buy a NEW longblock for $1500

KED85

THAT is a WISE suggestion, too!
I'd wave $1300 CASH infront of the closest GM part counter person you have & say, "Want some money today"?
Make sure you get a receipt & date of delivery!
That's a wise suggestion.

A.R.I engines has a 3.4L stroker long block for a little over 1K. Not to bad of a price.

thanks for the replies, i've been thinking about this project over for a long time, the new engine route makes since if i would have to spend money on a junk yard engine anyway. the gm 3.4 which one? they list the HO replacement and a F-body replacement thats new for 1600.00? people think i'm nuts for spending money on a 1987 car, but i already have 3,000 into a 500.00 car! thats just parts and all the labor done by me.

Honest.
AND it's a VERY WISE CHEAP INVESTMENT (pub is $6!)

thanks ked85, i will follow your advice, went to the dealer, of course they have to order the catalog. one question for you, why does you engine need a rebuild at 40,000 miles? problems with the heads?
