sweet. See normally that wouldn't fit, but you have alerady cut the big ass hole in your hood so your good to go!

...although, if I recall, I think you have to actually make the cut where the throttle body pokes out the top, which is further to the front but your scoop should still cover it... hopefully... and I'm pretty sure that the upper can actually be installed 180* reverse if neccesary, but I'm not sure if there will be enough room against the firewally to fit the TB on.. anyway it sounds like you've already got it on there so I guess you figured all that out? lol

The cowl hood has about 1/2" of clearance after the IAC was relocated.  :) And it is on correctly facing the front.

I was a bit disapointed with the low end on my 5.0 slow in 5th(.68) its okay crusing at 45mph, but even up to 75mph any hill requires a down shift unless you want to go well over half throttle.

plus side, no 1-d-1 shuffle when driving fast ;)

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

And what truck gearing would that be, good sir?

2:73 Final drive and .68 od ratio.

1st goes to about 40 mph, 2nd goes to about 65, 3rd i got up to 112. No idea on 4th and 5th, but one day id like to go try out the salt flats as its only an hour drive. with a bit more power i might be able to get to the 150mph club.

I always thought trucks had lower gears...

meant to ask this back in 09'
you mentioend early on the carb wierd angle and aircleaner in post 1.
going from 3.8L with the trans / gas pedal linkages on the drivers side as opposed to the 5.0L pass side, it makes sense how you oriented the carb.

the carb is suppose to slightly tilt forward for a reason but typically because of the carb intended lower intake.

is that a 4barrel?

the carb tilted forward so that when step on the gas hard, the floats dont cut out the fuel to the bowl.

my first reaction to your pics was  ... "why is the carb mounted backwards"...

Interesting thought about the floats. It is a 4bbl 500CFM Edelbrock with rear fuel entry, unchanged from how I pulled it from the box. I can't recall ever seeing a carb with the throttle lever on the passenger side.

  I didn't want to machine the intake so heavily as to bring it back to level for the carb, so I just let it lean back towards the firewall.

were the two larger butterflies to the front or to the rear when you bolted it down?

i agree, but the angle of the intake is the difference.
normally a carb intake would be lower on the front than the rear.
it *greatly* matters when getting on the gas pedal.  thats why the carb intakes are made like that.

im just thinking your upper needs rotated 180, the allen head pattern doesnt look like its fool proof.
this would orientate your carb prob about 2'' forward from where its at now.

what i do now is the lower is probably level enough with gaskets. the adaptor (upper) just seems to me to be backwards.

like i said,, i remember this thread, just forgot to post.

  I'll take pictures of it later. The upper is actually completely symmetrical and squared off, so there is no slope to it nor is there any difference front and back. Just a logo on the front flat.  The carb has the large secondaries towards the firewall and the choke plate/idle screws are towards the front.

  The lean of the whole thing is due to where the motor and trans mounts locate it. I wanted to drop the motor, but couldn't afford the parts necessary to do so. As it is, the oil pan has VERY little clearance to the steering rack.

understood, then the carb installed correctly yet its an picture trick there i see that makes the upper appear as though its lower on the front vs the rear.

I'm just gonna bump this with a "Check FB for the first video of it running on MS!"  Since I don't have a host site for the video here.  :)
