1970 Pontiac Firebird/Trans Am conversion project car.

The car has over 100,000 miles -I don't have the original speedometer so I cannot be exact.

This car includes all parts necessary to put back together except for the dashboard.

FullAutometerPro-Comp gauges including speedometer,tach, oil, water, gas, and volts custom fitted into stock trans Am aluminum instrument panel, new head-liner,andrear deck panel. Includes 4 brand new centerline rims, brake rotors,etc.

Body work is all done, just needs primer and paint. All body accessories are included such as stock air dams,foilers, spoiler, and air extractors to make factory Trans Am. Most of these parts are brand new in the factory GM boxes! Front fenders and front inner wheel wells are brand new.

Engine is totally custom 60 over 455(462cid) block with 96cc D-port heads fully ported, polished with stainless valves,custom 3/8 push rods,Crane aluminum roller rockers,stud girdle,insane.690intake and .740exhaust roller cam(280deg@.050),Venoliaultra-light custom pistons, custom lightweightwrist pins,nitridedcast crank, factory SD rods(Rockwell tested),7-quart oil pan, approximately 10.5 to 1 compression to run pump gas(with these heads), Doug Nash warrior intake extrude honed, custom Holley 850, MSD 6A on HEI, 2” headers, 3”Flowmasters, custom 10” converter, 390posirear end.

Many more parts included.Too many to list.

This engine and all of the parts listed have never been run or used. Most are in their original boxes. This is a perfect project car to have one bad-assTrans Am when you’re done.Projected power is over 600h.p.Engine, transmission, and rear end are already built except for stud girdles and rockers.

As for the body work:

We (as a family) have owned the car since about 1975.I am the brother of the person selling this car. I have done every single bit of work on this car since it came into our family. I know every inch of it.Our father purchased it from the original owner in mint condition. The car has always been in southern California. The car had sprayed on undercoating when we bought it. I don’t know if it was factory, or spayed on afterwards. The whole car has never been painted.It used to have a black vinyl top. The yellow you see in the photos is the factory paint.The car hasbeen apart for about 20 years.

About 22 years ago the car was hit in a parkinglot(the firebird was parked) in the left rear quarter, just at the rear of the wheel well. Usually, I do my own body work, but because it was pushed in about 6 inches(a little too much for me to handle), I had a friend who worked at a body shop take care of iton his free time. It appeared to me that he repaired it properly.If you run your hand on the inside of the trunk where the car was hit, there are no bulges or signs of any filler etc. When we took the car apart the last time to make it perfect, I had to clean up some of the work around that area because the body line and wheel well line weren’t perfect. I believe they are now.The rear wheel well edges on the top have been rolled under to prevent cutting of the 28X10.5 tires that were on the car. This was done without ruining the wheel well body line. You can only tell if you look up under the well, or feel it with your hand.

About 25 years ago, the driver door was backed into in a parkinglot(the firebird was parked again). I was a rookie at body work at the time, and although the door looked very straight when I was done, some areas had a much as an inch of body filler on it. So the last time the car wasapart(the same time we did the final work) we acquired a used door from another firebird and just had to do some minor work to make it straight. So the only major part of the body that is not the original is the driver door.

The car was in its only moving accident about 100 yards from home when we had a little incident with a neighbor. The left front fender was damaged right where it meets the nose. There was no major damage, and this dent stayed with the car for many years until this last teardown where we replaced both front fenders with factory GM Trans Am fenders.The passenger doorhashad only a couple of door dingsin the car’s life. The trunk and rearpanel have never been touched.

As for body rot, the back corners under the rear window were rusted through and unfortunately, I just filled it in withBondo(about a 2 inch length on each side). The small panel below the rearwindow(between the window and the trunk lid)was pretty rusted and was replaced.I only usedBondoto fill the rivet holes that secured the vinyl top to the roof. The rear wheel wells had just a touch of rot in the typical places, behind the rear wheels. Again, I only usedBondoto fix it, but as you can see from the photos, it was only an area covering a couple of inches. There is one part of the car that was actually rotted, and that’s the floor of the trunk.Because the trunk lid leaked during rains and washing the car, without us knowing it, because the originaljewtand flooring in the trunk was hiding it, the steel floor was constantly wet. We had no idea this was happening until this last teardown. When we removed the flooring andjewt, the trunk floor was rotted from one side to the other. Because we didn’t have the means to fix itproperly(cut it out and weld in a new floor), I just applied layer upon layer of fiberglass and resin until the floor was sound again. If you look at the trunk photos, you can see glimpses of the edges where the transition from fiberglass to steel takes place.

The nose of the car is original and not in the greatest shape. It has been bumped a few times, but may still be salvageable to an expert. We purchased a fiberglass nose replacement to save on weight, but it was somickey-mouse, I gave up on making it work. It comes with the car if you have any need for it.The left corner of the rear bumper was tweaked a little in the above mentioned parking lot incident. We had it straightened by a shop and then de-chromed with the intent of painting it black before putting it back on the car. I’m not convinced it is perfectly straight. The hood that comes with the car is from a 1976 Trans Am. It is pretty straight, but I haven’t worked on it yet.

I’ve spent countless hours aligning the body parts on this car. The gaps on thedoors(front and rear edge) are nearly perfect,and the trunk lid and spoiler were perfectly aligned before the teardown. Except for the front nose, if you primer and block this car, it will be perfectly straight.

If I’ve left anything out, just ask and I will be happy to answer your questions.

Thank you.
