what car can i find the 3.4 liter block that will be compatible with my 2.8 liter? and drop into my firebird? im really looking into replacing the block with a 3.4 liter and rebuild it. If i do this wil lthe heads of teh 3.4 liter work?

 

Ummm.... is the button invisible or something? Yes the 3.4 block will go right in. 93 - 94 firebird/camaro. All you need to change is the intake manifold, maybe the oil pan and if you do then you need to change your timing chain cover, accessories need to be swapped over and I think that's it. There are thousands of threads on this so you should be able to and find answers to anything I didn't answer.

 

It has to be a RWD (rear wheel drive) block for it to be compatable. Yes the heads will work, They are baiscally the same but have better spring bosses for a higher lift cam setup.

The block you need will have an "F" on it. Pictured below

 

and 95. Cali cars could be had w/the 3.8 in mid 95

 

Yeah bud... I'm looking forward to 3800 series II supercharger swap next year

Cause only the Shadow knows!

 

Yeah look for my 2.8->3.4 Long Block Swap Boogie thread and read it.
It's a bloody simple YET DETAILED swap.
I've done two, coached probably close to 100 by now and 99.9% of people happy with the swap.
Last unhappy person had to do more work that he expected to do the swap, but until I hear how well the project runs, I can't claim 100% of swappers are happy campers.
Yes seek REAR WHEEL DRIVE F BODY CARS from 1993-1995 for the subject (a 3.4).
Have at it and do your best to ask questions before ya lift a wrench.
PS BIG clue.
Open your hood.
See that current engine, cause that's exactly how the finshed 3.4 swap should look, yes it's that's deceiving and that's how much of the 2.8/3.1 stuff fits onto the 3.4 block.
