Okay doing a 3.4 engine swap on my 91 Camaro


Got the engine for 50.00


Osner said it had 95,000 miles on it. Need to order some parts for it.


Will keep you updated on the progress.

Nice. The 3.4's have the knock sensor bung on the block don't they? Other than that an extra bung it should be a straight swap right?

[kurfbird]

From what I read it a straight swap.

Has the same wirng as my 3.1 so should be no problem

I will be selling a 3.1 that has new headgaskets timing chain rear main seals freeze plugs and good injectors. Has good compression.

Update:

Got Headgasket Set and New bolts for it.
ALso got a good set of heads that I will be using. They had good compression.

Going to oreder oil pan gasket and rear main seal, timing chain and gasket kit freeze plugs. Will also check the bearing while I am at it.


Removed all the 3.4 stuff

Does anyone knw the size of freeze plugs ona 3.1 / 3.4

[blue89]

Oh ya, the 3.4 has a crank position sensor bung on the block as well. You COOOULLLLD do a sequential fuel injection setup.....

[kurfbird]

I think I am going to stay stock.

[d00012]

Any other performance mods? Or just the swap?

I'll be starting mine around summer.

[kurfbird]

Just the swap

Going to put new gaskets and heads on the engine

[d00012]

Ok, cool...I'm going to go the performance route. For what little there is for N/A without going the hybrid.

Well, I hope you have fun with the extra torque!

[91RSVert]

The 3.1/3.4 use metric plugs. Somewhere I had/have a brass set for one.........

[kurfbird]

I research it yesterday they are 34.3 MM

I remember seeing in the GMPP catalog that they no longer offered (well, haven't for like ten years) the 2.8/3.1 for camaros/birds/s10s and that GM offered an "upgrade" kit which included the 3.4 Kind of cool if you ask me. Good luck!

Jegs still stocks it, FWIW...

There are several write-ups of this swap on TGO if you need any help. I'd love to do it as well if I was planning on keeping the V6 in my 'Maro.

[kurfbird]

Okay

Was hot so waited till the sun went down.



Installed intake
Exhaust manifolds
Oil filter housing with new gasket
Engine mounts.
Collant temp sensor

Rented a slide handle puller and a pilot bearing removal tool. Was hopefully going to have the trans bolted up.

That it fopr now.

[Schultzy89GTA]
