73 Corvette Before & After

My Dream becomes a reality

Finally the car arrives, my dream is becoming a reality Car was ordered new with 350 L82, M21 4 speed, 3.70 Posi and AM-FM mono radio. Car was in original condition with build sheet and repair documents back to mid 80s and had been in storage for about 15 years

350 L82, was rebuilt about 13,000 miles ago but will be freshened up in the restoration. L82 included forged crank, rods heads had 2.02/1.60 valves, pushrod guide plates and screw in rocker studs. It was basically a 72 LT1 motor with hydraulic lifters

Always wanted a Corvette since I had a ride in a 69 427 as a teenager. Finally was in a position to buy one in 2006. The only stipulation was it had to be a 4 speed and it had to be a 68-73 "Bumper" car.

The car I found required a body off restoration to replace rusty frame, brake lines and 35 year old suspension bushings

Plenty of rust issues to deal with as disassembly continues

Corvettes may look all nice and shiny on top but there is actually a lot of metal reinforcements and a metal "Birdcage" Here you can see the rocker channel is rusted out and requires replacement. Luckily the Corvette vendors carry all the parts you need to restore a Corvette

This is the seatbelt reinforcement, Car probably sat parked over grass for long periods as all topside metal such as windshield frame was ok

Motor was in good shape so I just freshened it up with new rings, bearings, timing chain, Comp cam XE268, Edelbrock Performer intake, Headman headers

I found a replacement frame from a 73 Corvette parts car. I went to a local do it yourself sandblasting facility in the city and sandblasted my frame, wheels,bumper brackets,driveshafts and lots of other metal parts. The facility has a 200hp compressor with large sand hoppers and air supplied helmut. This sure beats trying to do it at home with the small 5hp compressor and no mess to clean up!

After about a year the chassis is completed. Rebuild included Stainless Steel brake/fuel lines, Energy Suspension Poly bushings, Moog steering components,Addco front/rear sway bars, 460lb front springs, 255-60-15 BFG tires, 2.5" exhaust with MagnaFlow mufflers, new rotors & Stainless sleeved calipers

even the headlight header bar was rusted out but again a new one was available from Corvette vendor

Before dropping the body on the chassis I needed to replace the rocker channels, various reinforcement brackets then clean and paint the engine compartment, floor pans etc

All the headlight buckets were rebuilt with new seals, new rad support and the wiring harnesses cleaned up

Finally, body drop day has arrived!. Its good to have a few helpers on hand to help guide things back in place

Sure looks a lot nicer than it use to. It will be a pleasure maintaining this now

Looks a lot nicer than the second picture. After hooking up dozens of brackets, fuel/brake lines,linkages etc its almost ready to fire for the first time.

First day on the road!! This was the first time I had driven the car except for the 4 test miles I put on when first purchased. With the 3.70 rear end it has a healthy appetite for fuel!

I attended numerous local car shows during the summer and met lots of great people. I still need to paint the car and replace the interior but at least now I can enjoy driving it while I finish it.

My 350 L82 was numbers matching and a little down on power so i decided to put it away for safe keeping and build a 454 for it. Found a late 70's 454 short block for $150. Machine shop bored it .030 over, line honed the crank saddles, decked the block, turned the crank .010/.010 & hot tanked the block. Used ARP crank studs & fasteners throughout, Speedpro pistons (10.5 compression) Procomp heads 305cc runners, 119cc combustion chamber, 2.25" intake, 1.88 exhaust, 2" headman headers, Edelbrock performer intake, Comp Cams roller rockers, guide plates, pushrods, Quick Fuel 750cfm carb

swap day, 454 going in I used most of the 350 components starter, bellhousing, engine mounts, pullies etc. During chassis restoration I had upgraded all the suspension and put in a Dewitts aluminum rad

40+ year old interior was worn out, time for a refresh

seats were really bad, no foam support, covers torn and seatframe was broken.

welded and sandblasted seat frames, painted with DP90 epoxy primer New foam and covers made a huge difference in driving the car. before I was almost sitting on the floor

Replaced Carpeting, Dash Pad, Pillar post mouldings, rebuilt seats I have new door panels but will wait till later when i paint the car

The rocker channel is welded to Vertical brackets that are welded up inside the front and rear pillar posts. There are also some rivets along the door sill coopersgarage.piczo.com

I used to do a lot of resto work. I've owned everything from a Lotus to 2 66 SS Malibu's, 3 67/68 RS,SS 1 1969 Z28, A very mint 1964 SS Impala a very rare high optioned car tilt wheel factory tach power ant, black with a grey/silver seats and door panels, factory fender skirts and the best of it all was the 327 375 hp with the M22 rock crusher, the second nicest car I owned, my first love was a 1969 Chrysler 300 2 dr hardtop with a 440 TNT 375 hp but I'm positive it was at least 100 hp more then it was advertised and torque was just unbelievable, hideaway headlights car was loaded power everything and climate control. I never ever knew how fast it could go cuz after 120 there was still so much more it would do, but I didnt have the balls to push it all the way. I've had Mustangs, Cougers a nice 68 Montego MX with a 351, buckets and console with factory A/C, they have become almost extinct, but I have been damned when it came to Corvettes I almost owned one that had been smashed up. nothing special a white 1980, but it was a Corvette, lol. These days I've been reduced to BMW's a 635CSi and a 1990 325 rag with less the 80k's both beautiful cars fast and handle well but I still haven't gotten my dream car which is a 69/70 Corvette. Oh but I wouldn't rule out a 67 big block with A/C,,but thats just dreaming. I loved working and restoring cars until I was seriously hurt in a workplace accident 9 yrs ago. Today my Hotrod is a 2007 Ford F150 FX4, at least it has that V8 growl, its loaded and comfy. I had a 72 Camaro with an LS6 for a spin, it brought me back to the days, but it wasn't a Corvette,lol. ,Congrats on your restoration, and its not a mutt its a Resto-Mod. I'm jealous, and too feeble to do that kind of project. All The Best!!!!moe

Thanks Dan! My car was featured on his site under restoration projects he once had but the free web site i was using went down some time ago, just never had the time to create another. The 73 Spot is an excellent site with lots of great tech articles. I enjoy reading the original road tests from the day.
