Patro46 With the LS3 swap now complete, I've decided to start the LS3/LSA Supercharger Swap with it's own thread. This build has been fun, unbelievably educational for me, and more rewarding than I ever dreamed it could be.

This swap has taken an already unique icon of American history and converted it into more fun than the engineers at GM ever could have visioned. From comfort, performance and handling, she has became something to be reckoned with, even by today's standards. e

I want to thank so many who have contributed to this build, as 5here were many. One of my favorites being those boy's from "down under" who took the time and silkscreened the mp3/radar/USB ashtray conversion top plate, using the same stencil typeset used by Chevrolet back when she was created.

Been a wild ride!

Patro46 It's been been a while since I've posted, but only got my car back from paint a few weeks ago, and I've been busy playing catch up.
Someone broke the wiper switch, so I had to replace that. While there I replaced both the worn and weathered center vents as the chrome was missing and several grates were damaged.
Also, earier in the build, when it came to the AC, I wanted to truly keep cool in the hot Oklahoma summers. In addition, I wanted my PCM to be able to control the AC using three factors.
1. Throttle position
2. Pressure
3. Temperature

By integrating a trinary switch in the high side, aND utiizing dual PCM controlled fans, I'm able to sit in traffic staying cool and not overheating, something difficult in old C3's.

Also, I've almost assembled all the required parts for the LSA supercharger. I finally aquired the blower, and have the new improved ZL1 hat.

I have the required blower drive now, and need to replace the compressor brackets to one's that still keep the compressor up high, but are fashioned for the blower idler. I've aquired these brackets.

What I lack is a fuel rail (200 bucks), injectors (300-400 bucks) and an adjustable harmonic balancer for the blower (500-700 bucks)

Other than those, I'm ready to go!

Patro46 It's been quite a spell since I've have anything to share as my car has been tied up at the body shop for.like 7 months now.

Anyway, I'm now moving on to completion of the LS3 engine. It had been my goal to install an LSA supercharger from the git go. Even down to the cam that's a custom grind Comp Cams stick designed for boost (even though she runs pretty good normally aspirated with that cam)

What stopped me then was because of having to go high on the compressor and the alternator with Holley's kit, there wasn't an option for the belt/tensioner kit from Holley, and there still isn't.....until now. LS CONCEPTS has created the drive that will now allow an LSA supercharger configuration to work with the C3 required compressor and alternator relocate kit!
I contacted them today and was informed I can keep the Holley alt/power steering bracket, but have to purchase their high mount compressor kit and the LSA drive kit. I have to provide the LSA balancer and change the PIA custom water pump I had to reconfigure and do it again to the LSA water pump, as the heater hose bibs are in the same place as the other one before modding. GRRRR on that, but Yay on the blower.
Time to start saving some green again!

Richard454 Good to hear it's working out for you!!!

Sounds like it'll be read for the Hotrod Power Tour!!!

Patro46 With all the preliminaries out of the way, a game plan has been formulated. Final damage assessment? Over $8500.00, and probably close to 10k by the time all is said and done. Yesterday, damage I hadn't seen was pointed out to me, and looks like I'll need to replace the front bumper as well. For parts I'm using Eckler's for the fiberglass and Urethane bumper and Al Knoch for the convertible top. He's about the same price but seems to provide the best product for the buck. There was also damage to the drivers side cowl lip. These are things I've overlooked, and am happy I have someone who seems to care about the details as much as I do. At this point, my hats off to David and Jerrod at Unique for handling not only the details of this repair, but in also dealing with the insurance company for me. State Farm rocks when it come to insurance, and they should consider this a free "plug". I figured we'd have a fight or two, but they were indeed fair and balanced, even leaning my way so to speak. I looked at 100's of colors in the Dupont line and a few others but simply cant play second fiddle in the paint dept, and stood my guns, insisting on House of Kolor's one and only Candy Apple Red with a gold base in the new "Shimrin 2" series. Stripes will stay a dark charcoal with a pearl effect.

For now we're finishing the tune, and she goes into the shop Monday for a 6 week venture on a complete color change, sure to emerge better looking when when she went in.

Richard454 Good deal-

Taking lemons- and making lemonade. Or what I call 'Plan B!"

You still have to make it over to the HRPT-being a passenger is not that bad....

brent319 Good for you! Glad you can make the best of the situation. The color should make the car stand out even more.

Patro46 I really want to thank you guys for all the support. I've been rather quiet, but I usually go through a period of silence while I gather up a game plan when tragedy hits in it's many forms and flavors. I've pretty much lived my life as if I had an obligation to take life's tragedies and somehow find a way for something good to come from it, being a lesson or whatever it may have been. Really, all this does is change the game plan, and the timing of it. I had planned on a re-paint, but had planned to deal with it next year, and just enjoy the car this summer. It really was nice enough to just leave it alone, but I've never been much of a fan of greens, so a color change was already in order. I WOULD be lying if I said it hasn't "grown" on me though. This just means I'm going to have to "get with the program" if I'm going to enjoy her this summer, so here is the gameplan.

Color change. L-88 hood.

"Back in the day", I used to shoot a bit of House of Color paints, and was especially fond of their Candy Brandywine on a gold base. Looks almost black until light hits it. Team that up with charcoal Metallic Z-28 stripes (just like she had btw), except I'll do a stripe work-around on the L-88 hood, just like a 73 Camaro I had in my early years. Also, paint has improved a LOT since I shot it on a regular basis. Usher in House of Color's Shimrin 2. I'll get all the advantages of a true candy paint with the ability to spot repair in the future, something that simply couldn't be done with the candy lacquers of yesterday. I'm also pleased to report I found a local shop whom I trust with my car, something that has never happened before with ANY of my past cars. After the battle with the insurance company, I'll finalize the game plan and initiate the countdown.

slofut I'm with Terry, it's a blessing in disguise! And no windshield frame damage! By mid-summer you'll be driving it with a new hood and top and parking in a new garage!

riggs 74 Glad to hear its not extremely horrible, maybe even a blessing in disguise, this may help you with the next step of paint and body. I hope everything works out in your favor.

I'd likely never let anyone do body work on my Corvette unless they had the same passion or at least understood my own. Some people get why we love these cars, and some people don't.

7TRoadster Well............. on the up side it isn't totaled, it's still drivable and from your description it sounds like most the damage was in the drivers front quarter. It sucks true, but could have been much worse.

You will rise above this, look for opportunities to upgrade during the repair process. For instance: if you ever wanted an aftermarket hood now would be the time. As I recall you were looking to replace the soft top yourself, now the insurance can replace it.

The good news is you will get your car back. Hopefully a new carport too. Hang in there, stay tough.

Patro46 Yesterday, I began to laborious task of putting together estimates for the insurance company. As far as damage, here is what she went through. When the roof collapsed, it literally came down around the car, except the area of the hood and drivers fender. The convertible top was penetrated, but the frame itself held up rather well. The area of the hood right in front of the drivers seat was pretty much holding up the entire enchilada, as it fractured the inner supports of the hood and left a low spot visible. The paint has been gouged down to the fiberglass in several areas. The car IS driveable, but it makes me sick nonetheless. Out of ALL of places I went for estimates, only one impressed me. To the point I hope I can afford him as his work is beyond outstanding. He was the ONLY one that took it personal enough to pick out what I'd been concerned about with the car, unlike the other shops. I'll post some pictures tomorrow.
