my search is not working first off and i did not want to look throught aww the post i am looking this up for a good friend of mind is ther any other bigger v6 motors that u can put in a 2.8 camaro 5 speed that u can use the 2.8 mounts with little mods thanx
----------
sry i did not mean to put 3.1 in the title

 

3.4 probly if u want to stay with the same trans. remeber the 3.1 and 2.8 are the same motor just the 3.1 had a bigger crankshaft

 

would there be a big performance boost from a 2.8 to 3.4 engine?

 

yeah the 3.4 was a bad little engine

would be worth it

the 3.4 was used in montes and Z34's and such

was lots better as far as power goes

have to watch head gaskets and such in them though

as with alot of other engines


commonly fail


put new ones on before sticking the engine in the car


save lots of problems later

good insurance for the engine life

2.8 and 3.1 are one in the same on the outside

just different bore/stroke/crank


externally they are identical, brackets and configuration and all that




good luck

 

would a 3.4 out of a 4 gen camaro work with the 2.8 motor mounts and the 5 speed 2.8 trans?????????

 

The 3.4 is a bored and stroked 2.8. Yes, a 4th gem motor is your best bet.

That is a 3400, a totally different engine. A FWD motor will not work without major modifications.

 

thanx that helps

 

FF, don't forget that the Lumina and Z34 of the mid '90s had the 3.4 DOHC, which is NOT a 3400.

3.4 from a 4th gen F-body ('93 to '95) would be the easiest swap that uses the same mounts and acessories from the 2.8.

 

Yeah, I know, but I made sure to say FWD to make it easy to determine what engines would work.

Could the DOHC upper end be adapted to a RWD block, though? I have seen the heads on ebay multiple times for cheap money.

 

Not even remotely close to swapping around.

 

EH, I figured as much, but am very UNfimiliar with the design of the DOHC.

 

Thats cool. The block has machined slots for the dohc part, then places for "timing covers" to bolt up to it.

 

I suppose I will nead the ECM and engine harness of the 3.4 right ????

 

QFT!

I have toyed with the idea of making a 4V/cyl pushrod 660, but the pushrods would be going through teh middle of at least 4 of the intake ports IIRC.

No, you retain your 2.8 electronics when you retain the 2.8 intake and accessories.

 

never thought about useing the intake manifold of of the 2.8 nice i think i will do that on his car but manifold and injectors will work with a 3.4 i did not no that wow

 

All you need to swap over are the accessories, intake, fuel rail/injectors, and timing cover and you should be good to go.
