thanks for all of the comments! yea it was well worth the work involved. there's no way i could just sit down and work on it. i just worked on a lil bit here, and a lil bit there. so it wasnt near as bad.

There is another of those in progress I understand. Apparently this other one has had its ears removed too.
I'm just not sure what I'm going to do with it once its done. But I'm sure ill figure something out.

well, its a kinda back and forth topic. you have a better up-top powerband, but down low the 3400 mani flows better with its angled runners. the 3500 is like ports on the bottom of a box

I've got some nice spacers to stick under mine if I do decide to use it. But to use it I'm gonna need a cowl hood of some sort.
I'm torn, I definitely prefer the looks of the 3400 upper. And I'm not feeling let down with its current performance. I'm ready to hit the track in mid-late April and knock this time down some more.

So if i install my 3500 upper on the 3500 lower i need a cowl hood??Doesn't alxsmt have a stock hood with a 3500 top end??Yes im hoping for mid to low 14's with my Lsd and a few other little plans before the engine build.Do you still have a open diff kurt???What rpm do you launch??

You only need a cowl hood if you wanted to use phenolic spacers between the upper and lower.

I'm still open diff and will be for a while. But even with that and the huge brakes I'm thinking a low 14.7 or high 14.6 could be in the cards in full street trim.

Im sure you can get there without a problem.What a pain it is sanding all the little spots on this intake.But it will look pretty when it's finished.
