3500 Sfi For Sale(350.00)

It's unfortunate that this thread deteriorated to the previous tone, but I feel it necessary to mention that I just went and checked the cam in my 2005 3500 from the G6 currently upside down on an engine stand and noted that an approximately 8 inch long screw driver went all the way into that center hole until the handle hit the end of the cam. So I guess I didn't get one of those solid camshafts.

Don't feel bad, I too have a 3500 cam and it is hollow. The 3500 cam is the same part # as the 3400 cam. However where it gets interesting is that the 3400 Equinox cam has a different part #

Ha Ha, no it's still in the block, I didn't know GM had a problem with roller cam failure that's kind of scary.

I think the roller cam failures is more due to the Leaking LIM than the cam being hollow.

Couldn't you just have played "telescope" with it to determine that?

goooooood!cause none of you know anything!first of all the cam isnt the same for the simple fact that the 3100 and the 3400 have a hollow cam which was a problem with them breaking.gm corrected that problem with the 3500.look at the diffrence in torque between the 2.i guess that doesnt count for nothing either?

Yup, thats the setup I recommend.

So should I get 3500 heads for my 3400 block?
Then will the 3500 intakes all have to go on there?


I still like the thread about port and polishing your motor with the heads still on.

The guy who wrote that made it sound like it was the way to do it!

"....crank the motor up to 4000 RPM and slowly start pouring the white sand in the TB..."

HA!!! loved it!!!!!

[SappySE107]

Not insane, probably in the 10.x:1 range. 3500 heads are 32 cc and 3400 heads are in the 28cc range.

[FallenZ24]

I just thought of something. If you put the 3100/3400 heads on a 3500 shortbock, wouldnt it net some insane compression? Because of the smaller combustion chamber of the 3400 heads.

Either way, this guys has no place on this site. Everyone is wrong except him. He is the almighty 660 God of Knowledge!

I was having a bad day until I read this thread. Thanks Larry for the great entertainment. It was a waist of 2 mins of my life.

[IsaacHayes]

Hmm. Good luck with the sales, but seriously you're not impressing anyone.

If you really think you are right, then build your motor, show pictures and post dyno sheets. Until then you can't dispute what has been proven and is common knowledge.

I love your email. LARRYSAUTOSERVICE@xxx

I didn't wanna display your whole email but that right there is classic. Larry's auto disservice is more like it.

[SappySE107]

Yup, you most certainly are done here.

[FNJ26]

your an idot!im done here.

None of us know anything. Amazing. The cam specs are the same. I measured them myself. Going from a hollow to solid cam is not a performance increase, its a durability increase.

Torque increase, you don't say. I wonder if its because the 3500 heads flow better and are a better design on the intake and exhaust ports. Better combustion chamber shape as well. Perhaps its the redesigned intake valve shape. Maybe its the shorter runner length and the better breathing upper and lower. Ive flowed them all. Oh wait, none of that would give you 16 hp. Its gotta be the .2-.3 compression increase and the non hollow cam. Oh, and speed pro stock replacement cams for the 3100/3400 are solid now as well. Guess I should add those to the store for a 16 hp gain even though they are the same stock specs.
