and all the other stickies at the top of the page.

 

^ This. Go to the junkyard and find you a 93-95 Camara with a good 3.4 cheap and swap it in.

 

is the 3.4 swap a plug and play mod or will i kneed a new wire harness and computer ex.

 

lots of info on here about the 3.4 swap..

 

It's a plug and play engine. You have to swap over your intake though

 

so the what about the computer? are they obd2? or the same obd1?

 

OBD2 started in 1996

 

Read my sticky........

 

step 1: do search
step 2: read
step 3: read more
step 4: begin engine modding

seriously though all the info is in the links at the top of the v6 forum

 

why would you bother swapping a v6? if you look around you could find an 8 for cheap. My brother bought his entire iroc with a 305 for 100 bucks.

there are many guys on here that have v8s for cheap. I have a spare 305 block if you want it.

In the long run, the swap even for another 6 sounds expensive.

I would think your better off getting a 305 auto in one shot for a few hundred and swapping that.

 

And you clearly haven't done the steps above...

 

fuel injected v6 to 305 auto swap is a wash u really dont gain anything except an extra worthless 2 cyls an extra hundred or so pounds of wieght and something like 15 or so more hp

 

To change over to a v8 you have to get a different tranny, rad, motor mounts, brackets, ect. It can get costly if you dont have a parts car

 

and different front springs

 

me and my dad were working on resolving the engine idle problem i had and as we were looking around we found a cam position sensor, so i already have a 3.4 and didnt know it. now that the idle problem i had is resolved we were able to advance the timeing 5 degres...it runs like a diferent car

 

So you got a lucky 3.4 swap?

Does it have the 2.8L EFI system?

 

yup! and it does still have the 2.8 EFI, i do have anouthere que tho why doesent it have a syrpintine belt???

 

More than likely cost, PO (previous owner) probably just took the pulleys of his 2.8 block and then used the same accessories that came with the car to keep the cost down.

How did you figure out it was a 3.4 again?

 

Cam sensor, f body 2.8-3.1s dont have 'em.

 

we found a cam position sensor
