Anyone Running 3500 Parts?

[-Alero-]

hey anyone using any parts from the 3500 on thier 3400?

i know the intake manifold bolt up, but it needs the 3500 TB which uses a completely different throttle linkage so its iffy.

well anyways, i was wondering if the 3500 heads would bolt to the 3400? and does the cam have to go with it? or is it just not worth it.

im just trying to find out how compatible it is exactly. ive been looking into 3500 parts but, not too many people have much to say about the hybrid setup. so i was wondering if any of ya'll knew anything about this setup.

You blew up your 3400 motor, right, just do a total swap

[-Alero-]

nobody likes the 3500.

i thought the 3400 had a little more aftermarket support than the 3500, or am i wrong?

[Redog]

No you're right the 3500 is too new yet

[-Alero-]

well i mean the alibu has been out i think as long as the alero and grand am, maybe longer, and they have carried the 3500 for a while.

[Redog]

The 'Bu "N" body had the 3100 motor, all the 3400 is, is a bored out 3100.

The 3500 is in the New 'Bu and the G6, and I think the LaCrosse

[-Alero-]

hmmph, yeah i knew it was bored out, and the 3500 is the bored out 3400.

thats why i was hoping to see if anyone has tryed a hybrid setup.


and Ken, the 3500 60* v6 was in the malibu's....i know its 99+

^^ thats thebest link i could find (i know its canada )

[bu01]

the malibu 97-99 ls and 2000-2003 had the 3100sfi. the 3500 came in the new platrform. not the N body

What about going with the 3.4 DOHC?

[jturkey69]

as in old school 3.4 dohc??...not a wise choice IMO...search around more for the 3400...you can find forged pistons (mfuller knows the part number) and much more at www.60degreev6.com

Quoted post

The 3.4 DOHC was based off of the 2.3 QUAD 4.

Both have had serious issues including cracked blocks and piston problems.

Trying to help you out man, but again you know all. The New Malibu in the link is NOT an "N" body car. The 3500 motor is not a bored out 3400 motor, the 3500 is a different motor altogether.

The 3500 motor is in 03+, the 3100 is in the 99 to 02 Bu's and the 97 and 98 cutless, which became the Alero in 99. Of course, You're right and everybody else, including the GM plant in Lansing, is wrong

I wouldnt say they are completely different
as far as swapping in a 3500 in plac eof a 3400. our computer would need some serious work to control it
however many parts off the 3500 can be used on the 3400 to improve the 3400.

their TB is drive by wire so you would have to get rid of that some how and adapt back to a regular cable style control
easiest would be to use an adapter plate and a stock or larger bore 3400 tb.

heads would bolt up but as far as I know

The block of the 2.8, 3.1, 3.4, 3.5 and the new "3.9" (which is technically 3.7L but whatever) pushrod 60° V6 are all basically the same, with minor improvements from generation to generation (the older 2.8 and 3.1L engines are 1st gen blocks IIRC, the newer 3100 and 3400 are 2nd gen and the 3500 and 3900 are 3rd gen, although I'm not totally certain that the 3500/3900 block is any different from the older 3100 and 3400's, check www.60degree.com). Likewise the heads were changed and improved in design from generation to generation along side the block. The heads from the new 3900 240HP engine should bolt onto the block, but you'd have to bore out your block of course, and I doubt you could use your old intake manifold, which means you'd have to use the new 3900 intake manifold, which means you'd have to use it's throttle body as well and I'm sure it has electronic throttle control, or figure out a way to mount the older 3400 throttle body on the new 3900 intake manifold. Also the 3900 has variable valve timing, which means it likely wouldnt easily drop into the 3400. Which is sad because it's probably a very nice street grind cam, something along the lines of what most people here would be looking for.

I think the old 3.4 DOHC block is based off the design paramters (IE the stroke and bore spacing) of the 3100 and 3400 blocks, but obviously with changes in the lifter galley and at the front of the block for the cam chains. And likewise with the new 3.6L DOHC, it shares it's bore spacing with the pushrod sixes but I'm pretty sure it's been more thoroughly engineered and refined such that you couldnt really gimp any parts off it.

custom mounts would more than likely have to be made since where our mount is on the passenger side they have all kinds of stuff in the way
not to mention numorious things like water inlets and outlets moved arround
it could be done but not very easily
however adapting the varible runner intake to our ingine could prolly be done
as for the heads you would have to make sure valves would clear our cylinder walls
the bore is quite a bit larger and valves could possibly hit the cylinder wall sides
if I get ahold of a set i will see if they will fit or not
many of the parts could prolly be used
I know on the 3900 the cam journals are bigger to make room for a higher lift cam so in that aspect the block is pretty different
I also herd they lowered stroke or somthing in the block to get a 3.9
i do know you cna adapt a 3500 crnak to our engine
matter of fact I'm prett sure thats all j-body performance is doing for their forged crank.
the one they sent me looks majorly like the 3500 crank just with timing notches cut in for our engine and some numbers ground off

Actually, everything said is true, except for the stuff on the 3900. The 3.9L has an entirely different block than the current 3.4 L. It has offset cylinder boars to help with cooling. This meaning if you pulled that heads and looked down on the cylinders, they are not directly one in front of the other as you go from front to rear of motor. That being said that says that heads are different. Also the front of the motor is different to house the cam shaft phaser, as this motor has variable valve timing. Also the intake is variable length. This motor is big time different from that of the current generation V-6's

Now the LX-9, which is the current malibu and G6 3.5L does share some commonalities with the 3.4L but there is more differences that one would think.
