1984 Trans Am, Holley 600.

Ok I got the 305 to idle around 800 to 900 RPM ( got a dodgy tac so its hard to be specific on RPM) but when you pull up at an intersection put the car in neutral and take your foot off the pedal it dose not drop under 2,500RPM, when back in drive it sits around 1,400RPM, unless I get under the bonnet and turn the throttle back.
The thing is the Holley has 2 very strong return springs one going back to the plate that holds the cable in place and one going forward to the front rocker cover bolt.
Another problem solved, the arm on the base of the carbie that operaits the choke cam was catching on the adaptor plate so I took it off and cut a little bit away and now it operates nicely.

1984 Trans Am, Overheating Problem.

Got more problems :(.
Over the last weekend the temp got a little warm and the car really didn't like it, Sat: 34'C and Sun: 33'C. The car got to 260 in the red on the thermo 5 times, A 10 min drive and it was on the red as I pulled in to the driveway.
So last night I started to rip stuff off the front end to try find a way to get better air flow through the radiator. I took the front number plate off, removed the front grills and gutted the thermostat. I took the number plate (being the only piece of spare metal at my fiance's place) and screwed it in to the plastic thing under the radiator to direct air up. Well as for the drive on the way to work thismorning the mods must be working because the temp gauge didn't go over 160 , hopefully it will keep it cool on the 36'C drive home
(THESE MODS WORK VERY WELL!!!)
Going up hill going 100kmph in third gear on a 36'C day the car didn't go over 220, once on a flat road at 100kmph in forth gear the temp dropped to 160 to 170. Now that is a huge drop from my 260 over heating temp on a 34'C day on a flat road.
I have a sheet of 600x250x2.5mm stainles that in cutting and shaping to make a under car scoop to pull air up in to the radiator. cant wait to see how this will work over my (number plate) air deflector of 120x300.

Works Great! The car (Under load on a 34'C day) it never went over 180 and normal driving it sat on 160, IM very happy with this outcome.

1984 Trans Am, Not Shifting Back.

I have an issue with the trans now well it is to do with the new carbie, under load or when accelerating in 4th gear it is not shifting back to 3rd. Now it goes like hell when I manual shift back but it refuses to do it on its own, it also jumps from first goes in to second gear for like .8 of a second then jumps in to third and it makes it a bit sluggish off the line.
Ok I know what caused this little problem, Stupidity! Not researching before working on it.
There are two cables going to a third gens carbe one is throttle (normal) the other (what I thought to be a disconnected cruise controls) is a T.V (throttle Valve) cable. This cable is VERY important for a 700r4 trans, it tells the trans how mutch the throttle is open.
But now this cable is connected and set correctly it runs fine again.

1984 Trans Am, So Far So Good.

The holley is on and running sweet, I stuck with the stock intake with an adaptor plate for now.
give it a few weeks and let my finances grow and we will see how it goes with the manifold.

1984 Trans Am,Threaded.

I ran in to a little trouble with the Holley 600, 3 of the front bowl screws have no thread left in the carbie so I have found a place that will helicoil the holes with steal thread for only $4 eatch.
I will be getting this done tonight and i am picking up my intake manifold on Friday and installing them both on Saturday.

I will update the sight on Sunday and let you all know how it is going.

1984 Trans Am, Time For Some Upgrades.

IM getting some goodies for my ride, IM picking up a Edelbrock Performer intake manifold and putting a kit through my Holley 600 that has been sitting around for a while.

Hopefully these mods give the car a little more grunt and better fuel economy over the badly modded Quadrajet that spits raw fuel out the exhaust when the car is revved.

1984 Trans Am, Getting There.

Now the oil leak is solved, it was pissing out the back of the left rocker cover going down the back of the engine.

the wire for the temp got burnt on the exhaust and was shorting out. (replaced and now working).
