1975 Corvette Stingray Resto w/ Performance upgrades


Well as fate would have it a deal was struck and while I may not be "big balling" in the S600 I got the next best thing... Another 560 SEL!

It would appear that in this project I have my work cut out for me. Complete interior gut, seal and paint along with mechanical / performance upgrades ending in the preping of the entire vehicle for a re-spray.

It's a big job but the truth is these Corvettes are somewhat small and compared to the 4 door sedans and even the 2 door Camaro/Firebirds and Mustangs that I have been working with these early Stingrays are pretty straight forward.

I have many photos I am converting and will update this thread to include the entire process. I have a lot of ideas for a "really cool" 75 Stingray and as I mull them over with the owner Ill share them with you.

For now the main goal is gutting the interior to clean what appears to have been a small mouse infestation. It's a real shitty job but the ole' girl is cleaing up nice.

RE: 1975 Corvette Sting-Ray Resto w/ Performance upgrades


Hey SELLC,

Really cool looking car...The era just oozes class & big performance without being over-kill...I like the '97 model you've got posted aswell, but I think that this old-girl would leave it for dead as far as desirability goes when sat side-by-side...Why not go for a 454 or 427 up-grade...

Cheers,

Rastus

Yes the Stingray is a classic no doubt... It's almost 25 years older than the Trans-Am.

The vintage cars have something special about them. But keep in mind that Pontiac is no longer, which could make for a "rare bird" 25 years from now... No Pun intended LOL!

The Corvette Stingrays (big block models excluded) were pretty slow back in the day for a sports car. I would highly doubt the Corvette will hold a candle in terms of performance to the current Trans-Am build I am doing in the other thread, this is because the owner of the Corvette is not really big into "Performance" or "Racing" and that is not the focus on the Corvette. With the TA it's pretty much all about the performance.

Awhile back I did not care much for the look of the older Stingray Corvettes but since this one has been here it has grown on me. The task with the Vette is more or less cosmetic with some performance improvements. Not going "all out" in terms of the engine as far I know, but that could change.

Neither of these cars are mine, so I can only make suggestions and they either get apporved or denied but both of these projects should be a whole lot of fun when finished. Cool part is that everyone can see them thru the process.

Well... We just got approval/deposit for this project today.

FULL ON BODY OFF RESTORATION! Complete with Hi-Po 350 engine overhaul!

It's going to be one hell of a transformation!

Yo SELLC,

Yeah, she'll be a great car again !!! I must admit though, I really like the way "427" rolls-off-the-tongue LOL. Still, there's so much more magic that can be waved over a 350 I suppose, & probably more ponies to be found when sought after...I know it'll be a while away, but a nice little video when completed will be really cool to enjoy !

Cheers,

Rastus

He's been steady with the $$$ so it should be the first one out once the weather breaks. I too am very excited to get the before and after photos up, and of course the mandatory burn out video!

Trust me Rastus, the Corvette IS the KING OF THE HILL in terms of power, style and performance when it comes to sports cars. In just about any setting the Corvette demans attention and an expectation of raw power. My mention of Firebirds is only due to a soft spot that was for the "F-Body" in "General" (no pun intended) when I was growing up (see link http://autotrend.activeboard.com/t8171625/photos/ ) and we can leave it at that.

It is amazing the twist and turns these performance overhaul / restorations can take. At the start of this project I knew this old vintage Corvette was capable of a show stopper. I may have underestimated the owners interest in this project, because at any moment, drop of a hat - he is there with cash. Not only that, he has means to have a brand new engine and transmission dropped off at my door from GM in just about ANY configuration. Then again, the owner is a W126 lover so it's to be expected. LOL I'd like to have performed a 350 overhaul on the existing engine block, but it is currently .030 over and the fit of the pistons is as such that really it's not worth it trying to take it over .030 IMHO, but we will see. This is because right now all focus is on body and restoration. Getting this vehicle down to the bare frame, removing and taking inventory of the parts is a job in itself, but if we are to get what I consider to be "better than new" result, it's going to require every nut and bolt to be given attention. That being said EVERYTHING has to come apart and start from the bottom up.

So first up on the agenda to get the fiberglass body off the frame was stripping the interior, doors, hood, t-tops and getting ready for engine removal.

With the entire interior removed, dash and air box I am able to media blast the inside (aka soda blast) to remove all of the old sound coating for its soon to be brand new dynamat. We are dealing with a prior rodent mess and this process of cleaning, blasting sealing, painting and sound proofing is very important. As clean as the car was to start it's obvious the vehicle spent its winters off the road and something had to give. In this case it was all the things that go along with the glorious barn find.

First up is a trip to get some supplies. Here is the soda that will be used on the fiberglass. I also have silica media that I plan on using on the frame and seal body cage, all of which will be blasted and sealed prior to it's fresh coat of PPG paint.

These tools were purchased exclusively for this project, and I would imagine they will come in handy but a test run was made on a 1989 420 SEL that we are getting back in order and most of this stuff works real good. There is no getting around the hours, but the end result is where you have to keep your eye. Sometimes that can get changed up, but when you take the stance that if something is going to get done, and done right; everything else is secondary. To put things in perspective, someone hands you a Corvette and says to you "I want it better than factory" and you will soon come to grips with the scale of such a task.

So you got to love how GM ran the exhaust thru the cross members on these cars back in the day. I once knew a guy by the name of Mark who could bend this entire system from memory out of raw 10 foot sticks of Sainless steel without the car even being at the shop yet! Talk about amazing! What's not amazing is the job that was done on this exhaust system, as clearly this engine was being choked off and the "cherry bomb II" style mufflers gave a classic old old rumble, but this system gave nothing near what a Corvette SHOULD sound like. I think this is the first thing to go!

Having removed the fan, radiator and support it's clear this vehicle could make some extra horsepower and show off it's new motor with an electric fan, getting rid of what was an ugly fan schrode. Given the long nose of the Corvette one must pull the engine from the side of the car.

And away she goes! It was at this time we made bets on wether or not it was going to still have it's 4 bolt main block.. I won the $1.00 bet! LOL

"Green-Horn Rick" showing off his freshly picked cherry.

 

Pay up Green Horn Rick! It's a 4 bolt! LOL! Clean, but already punched over .030

It's very interesting how these headlights work. They opperate off vacuum and springs. Kind of a bugger to work with, but thank goodness everything was pretty straight forward once you got all the framing and front bumper out of the way.

You can see here the interesting way these cars are made, but most important it's just about time for the body to come off so we can get cracking on the chassis and suspension.
