forcedfirebird -- you wont have the same issue that myself and driver_10 might have, because you have a third gen and the engine not only sits a little bit differently, but your height limiting factor is in the bottom of the hood, which can be changed by going to a SS style or cowl induction.
the limiting factor in the 4th gens is the cowl, or area the windshield sits on top of. the only way to change the height of that, would be to notch or cut the windshield and then move things around -- a much more difficult task than just changing the hood.
While driver_10 used a full 3400 engine and custom motor mounts to drop the engine - I used stock motor mounts and only the 3100 and then 3400 topend, so my motor sits in the stock 3.4 location. WITH THIS SETUP - i have 1/8" clearance between the top of the 3400 plenum with the "3400 sfi" shaved off (had to use my rotozip) and the underside of the cowl - "top of the engine bay"
the 3500 plenum is the same height as the 3400 plenum - WITH THE "3400 SFI" letters on top. when i tried putting the 3400 plenum in before i removed the lettering on top, it scraped the cowl. it would have meant that the motor would have been directly tied to the rest of the car, and i would have negated any effects of motor mounts (think solid mounts...rattling your teeth out, etc).
the height is different - because i am measuring differently than driver_10 is. if you make custom motor mounts (which is something im considering having done) - i could use any plenum i wanted to. the other limiting factor to me right now, is that im using the stock k-member.
there are a lot of differences between everyone else's "3400 setup" and mine - being that i did this myself, when everyone said it wouldnt work, and i had to invent everything as i went, i used what i had on a VERY limited budget.
consequently, i am using the stock 3.4 tune and because of the cam i have in there now (its always run a little off) the engine is just dumping fuel into the motor. i currently have a 10.5:1 Air to Fuel Ratio (rich) running the car and i probably get around 8 mpg. (im not kidding).
on my last dyno - 3400 heads and aftermarket cam - i recorded 184rwhp / 212rwtq. if i could tune (working on it), those numbers would go up...
something to look forward to i think lol.

something to look forward to i think lol.BUT, as Driver mentioned earlier in this thread, he managed to drop the motor by 1.5", and that should give more than adequite room to do a 3500 upper end swap.
I'm hoping to get 250hp N/A, and put about 20psi on it
. With a MegaSquirt tune, custom headers, LS6 springs, ported/polished, 75mm TB, and 1.7 rockers riding on a 262 cam (maybe 272 if lift isn't too excessive), I'm thinking it is possible. At 20psi, I should be able to get over 500hp. The most I have seen out of a 660 is 475hp, and I want to push the limits of the little beast.The next question, is how am I going to get enough traction?
