So swapping out the top end of a 3.4 to a 3400 is not easy...

[Shadly]

Man, that setup is so nice looking, I'd do it just for the visual aspect! I hope the rebuilders don't F it up. Looks like I'll be in San Francisco this weekend, so I won't be able to check out that engine compartment or visit with GMEternal. I'll be getting a free ride on this! I'm sure you understand, right? I [img]graemlins/love.gif[/img] my job! I thought I was going to get to use a G-IV, but this will do nicely. Maybe I can come up there next weekend.

On the exhasut manifold header idea.

coouldn't you jsut use the FWD ones, and cut them off very high, and cusotmize them to go in about the same place as the stock Y-pipe.

As for modifyng the firewall, you think a plasma cutter and welding in metal plates to "box" in what you cut out would work?

Just somehtng I was thinking up if I were to ever do a small block conversion.<hr></blockquote>

ok. so heres the thread that should end all the confusion on the whole exhaust manifold bit:

the exhaust ports are the EXACT SAME configuration and alignment as the 3.4 RWD iron heads. there isnt any difference. the DIFFERENCE: D-shaped exhaust ports. not a huge deal, just gotta do a little grinding with a dremel to make everything work.

the only trouble i am having, is that the spacing of the BOLTS is too far apart (top to bottom) .. the bottom bolt on the gen iii aluminum heads is farther down than the one on the 3.4 RWD iron heads. not a huge deal, im just gonna notch the bolt hole out on the exhaust manifolds and there i go. [img]smile.gif[/img] i could always get headers, but i dont have the money for that rite now. just the heads/intake will work. headers later.

Well, it's Thursday. What's the story, Russ? Is there a severely overpowered beast sitting there next to your car?

[black34v6]

LOL. overpowered beast..I like that. remember you are talking about a 3.4 ;) j/k -- anyway, no I still haven't heard from Coast Motor Supply about the engine. I'm gonna give them till around noon today, and then I'm gonna call them and ask whassup...

ill keep everyone posted as i know that i have EVERYONE with a 3.4 on the edge of their seats lol.

edit: so its friday, i called coast. we are looking at no sooner than NEXT WEDENSDAY. apparently they had problems (this was the expl.) getting the right pistons in. &lt;sigh&gt; ill keep you all posted.

Russel what do you mean by chp in your sig?

[black34v6]

chp = crank HP. or HP at the crankshaft, without the driveline on it.

basically when the 3.4 is rated at the factory, its rated on the engine, without anything else attached. thats why when you do a dyno, the numbers come out lower and you factor for driveline loss (such as tranny, driveshaft, gears, etc etc.) most manuals get a 15% driveline loss (average) -- i have a T5 transmission, manual(5spd), so i added back 15% to find out that my dyno (i got the car put on a real dynojet months back) that came to 140.2 HP / 183.6 TQ..

i got:
(you divide to go up, multiply to go down)
140.2 / .85 (15%) = 164.9 (rounded to the nearest 10th)
and:
183.6 / .85 (15%) = 216 (flat) -- so it looks like i miscalculated the first time LOL. o well no one is perfect, ill have to update my sig. anyway, so this is how it compares:

factory:
160 hp @4500 rpm
200 tq @3500 rpm

me:
164.9 hp @ 4500 rpm
216 tq @ 3500 rpm.

anyway, thats what it all means. hope that helps.

what happened on your first run?

[black34v6]

the little dip is a misfire. its cause the engine was in a broken state when i made that dynorun.

[black34v6]

ok so this motor shop i took the engine too is beginning to piss me off.

they said TODAY it would be done, around mid-day. well its mid-day. no calls. no anything. im gonna give them till 4:30. if they dont call by then im gonna ***** at them.

wish me luck.
