TWO LANE BLACK TOP

Y'all are welcome...

I've always liked the Reatta's too...I think they're really cool cars...Wouldn't mind having one myself...Coupe/Convertable either one would be OK with me...

The owner of the Solstice added the hood scoop to it...It also had the trunk lid from a Saturn Sky added to it because he liked the Saturn rear spoiler better than the Pontiac...

Have been seeing a Northstar powered Cadillac Alante..Around the area here recently too....Will try to snag some pics of it...When/if I see it again....

14 to 15 inches of vacuum at idle is really not a problem...Do the Power brakes work OK. ??

Just for my own curiosity...What Are the cam specs @ .050...

intake..duration -n- Lift..

Exhaust..duration -n- lift..

Lobe separation angle (LSA)...

Frosty...

Just to satisfy my own curiosity...And think you may able to enlighten me..Bonne61 has a thread...Brake Upgrade Advice...and I have a question sort of related to that thread...

GM used two different power brake systems...The Delco-Moraine set up...And the Bendix set up...Both the systems were used simultaneously across all/some the brands for a few years in the early 1960s...So my question is...What determined which cars got the Bendix system as opposed to the cars that got the Delco-Moraine system...Was it determined by which assembly plant the cars came out of...Certain production dates...Certain shifts...Supply pipeline...ETC..???

Any insight that you may have to this question would be appreciated...

Thanks..

From what info that have able to gather....In order to upgrade to a dual circuit Master Cylinder...you would have to swap out the Bendix power brake booster...For a Delco-Moraine power brake booster...As far as the brake pedal assembly...I'm unsure if the Bendix unit would properly work with the Delco-Moraine booster...As it is very possible that the brake pedal ratio/angle on the Bendix system would be incompatible with the Delco unit and would require the brake pedal assembly from a car that was originally equipped with the Delco power brake assembly in order to maintain the proper geometry and pedal ratio for the system to work correctly... 

Great car...(rare and fast)

I Especially like minimalist Stripper Pontiacs...

When the engine timing Marks on the damper/timing tab are lined up to zero (TDC)...Have you Physically verified that the engine is actually at TDC...?? (Both the intake and exhaust valves fully closed and the piston is at its highest point in the #1 cylinder)...The reason I ask is...Because the outer ring on the damper/balancer can/will slip around on the center hub...And the timing mark will NOT be accurate...Even though the timing mark on the damper indicates TDC....In actuality the engine timing can be several degrees off...Possibly causing your detonation issue...Might be worthwhile to check out...

 What sized jets do the Carburetors have in them...?? 

When the engine was redone was the cam set straight up or 4 degrees advance...?? 

Are there any flat spots..When accelerating through the RPM range...??

Frosty...

Thank you for the kind words and great photos....I'm certain that our paths Will cross again in the future...Look forward to it...

Very cool. I have heard of the Pro Am. There should be a gold plate on the dash telling you what number (out of 100) yours is.

Based on what I know, this was mostly cosmetic changes to the car, regardless if it was a base Firebird, Trans Am, or Formula. Chattanoga Choo Choo (CCC) did not alter the drivetrain in any way. So if it was a V6, it stayed a V6 car. a TPI 305 stayed a TPI 305, etc. I've heard that most of the cars were base Firebirds.

CCC was a dealer conversion company, and they added the large (non-functional) hood scope, the ground effects package, wheels and tires, dash plaque, exhaust tips, and perhaps some other interior mods. Most were solid color cars, but there were a handful of two-tone cars as well. It is my understanding that the cost of a CCC converted Pro Am was close to the same price of a Trans Am.

These are sharp looking cars especially when they were new. I rather doubt that these cars are particularly valuable or desirable. I hope I am wrong on that point. However, if the car started life a base Firebird, then the value decreases substantially. Given your pictures, your car might have been a Formula to start (a VIN check will confirm that), so that has some value plus it is a V8 car and not a V6 car. Given that CCC was located in Tennessee, it stands to reason that a larger percentage of the Pro Ams can also be found in Tennessee.

The car in the pic appears to be a base V-8 Firebird...With Throttle Body Fuel Injection...(TBI)

The Firebird letters on the fender is what gives it away...(Formula/TAs are badged differently)  The Trans Am version would have the air extractor in the lower fender behind the front wheel...The Formula/Trans Am version will have 4 wheel Disc Brakes...16 inch wheels and a 140 MPH speedometer...And of course (305/350 CID) Tuned Port Injection....The base V8 Firebird will have Thottle body injection (305 CID)... Drum brakes on the rear...With 15 inch wheels...

The same company...Choo Choo Customs...Also did a different 3rd gen Firebird conversion known as the Bandit II...Kind of the same as the Pro Am...With a different hood scoop that simulates the 2nd gen Shaker...With specific Bandit II graphics/wheels...They also did an El Camino SS conversion with the 80s Monte Carlo SS style aero nose on it...With special El Camino SS Graphics/Wheels...Have seen in person a few Bandit IIs and SS El Camino's...through the years...But have never seen a Pro Am...

Cool car..

Welcome...

Cool car..

Old Car City USA...

Great Pics...I'm surprised that I have never seen/heard of the place before...Very possibly... Future road trip...
