I'm just starting on my project so I thought I'd post some info and pics.

This was my sister in law's driver for several years until she retired it about 10 years ago. The car has rust in all the usual places (i.e. rear quarters, trunk drops, wheel wells, back glass, a little in the trunk pan, etc). The trough in the panel under the filler panel behind the back glass was rusted completely though. The back glass has been leaking for years.

The victim.

My sister in law keeps telling me how much power the car has and how well it handles. Wait until these are installed. Then we're starting to talk about power.

The L99 is out of a 2010 Camaro with 125 miles on it before it was replaced with a LS7 and the 4L80 is a GM rebuilt tranny. I also have a '67 12 bolt housing and a new eaton posi. I'm thinking either 3:55 or 3:73 gears

The current thinking to go along with the drive train is:

DSE suspension (Possibly ATS spindles)
Kore Brakes
17 x 8 w 245s and 17 x 9.5 with 275s or 285s (may shift to 18s rather than 17s)
Stock black interior - w/buckets
Marina Blue - Possibly with SS badging.

Re: 67 L99 T56 Project

Well the project has been moving mighty slow but there has been some progress. I've decided to change my choices a little.

For frame boxing I used the inner sections out of a damaged El Camino frame. Kind of like the FX kit so it should be at least as strong if not stronger. I also used the rear sections from ABC Performance. At this point the frame is pretty rigid.

- Mini tubs (should have decided this before I put new inner fenders in)
- 275/35/18 up front and 335/30/18 out back (gotta love them big tires)
- T56 Magnum (gotta have the man pedal)
- Magnacharger (I told my brother when I was 14 I wanted to blow the car)
- DSE suspension - dual adjustable coil overs front and rear
- Wilwood brakes 14" front 13" rear

Here's some shots of where I'm at on it. Should get the body back from the media blasters this week.

Sweet, building a 67 myself. Interested to see what mounts you use and also how that 4L80E fits in the tunnel!

On LS1Tech there's a couple of builds that used the 4l80 with very minor mods (i.e. big hammer where the cooler lines come out) so you may want to check over there as well as some of the builds here.

I ended up selling the 4L80 and bought a T56 Magnum. Originally I didn't want to do it because of the tunnel surgery but..... I plan on street driving and possibly autocross vs drag racing so the T56 ought to be better for that. If my calcs are right I think the 3.42 rear gears I have in the 12 bolt will be ok. The final drive ratio is slightly better than 4:11s with a close ratio muncie with a 2:20 first gear (i.e. 9.04:1). I bought the close ratio T56 which has the 2.66:1 first gear so with it and the 3:42s I'll be at 9.09 final drive ratio. Plus the magnacharger will make loads of torque down low. Also I should be able to cruise at 65 at 1800 rpm in 6th.

On the mounts, I have the Edelbrock mount kit that I'm going to use to initially position the engine/transmission. From there I'll trial fit the Flowmaster headers to make sure they fit. Ultimately I plan on making my own so I can move them back to align with the front cross member to give room to mount the AC compressor low on the passenger side. I'm planning on using 4th gen Camaro clam shell LS mounts on the block and build my own frame mounts.

Awesome list, I will be watching for sure! Where did you find the 335/18 KDW's? They have been impossible to get for some time.

I bought the 335s from a guy on the pro-touring site that decided he wanted to go to 19" for his Trans-Am. He is out of Canada so I got stuck with shipping + duties. They were a little expensive but I really like the tread pattern plus they are new and never mounted.

Also, I had a set of 285/40/18 and 255/40/18 KDWs that I bought off of craigslist locally for the car. Initially I was going to use the 255s for the front so I wanted the rears to match them. After getting the 335s and doing more research (especially Tom's '66), I decided to move to the 275/35/18s for the front.

I guess after selling the 285s and 255s I didn't come out so bad.

What size wheel and back spacing do you have for the front and how are you getting a tire that wide to clear? My 17x8 with 4.5" bs and a 255/50 rubbed the top inner fender on the outside edge close to where the outer fender ties to it. My car was about 2-2.5" lower than stock at the time.

In the rear I am banking a 20x10 and a 275/35 is the best size unless you mini tub it.

I haven't ran them but I'm basing this on a couple of others (It seems like 1 was an El Camino and the other was a '66 or '67 running 275s all the way around) and on Tom's 66 - "front: 18x9.5" with 6.5" BS with a 275/35-18. If we had it to do over again and Vintage Wheel Works offered it, we would go with a 9" on the front with a 6" or 5.75" BS. Right now I have a small amount of rubbing on the anti-swaybar at full turn. We're also running a splined anti-swaybar which gives us a little more clearance than a standard tubular bent bar. We also had to run a 1/8" spacer for our wheels to clear the C5/Baer brake calipers."

On the rears, I've heard a 285 is the widest without mini tubbing (I believe Tom was running those before he mini tubbed). Originally that was my path but my buddy talked me into mini tubbing and now I'm half pregnant .... or maybe a little more since I already bought the rear tires. 20's might be a little different because of the tire height.

I'm thinking about getting a WheelFit tool before ordering wheels to ensure clearance since the Wilwood brakes add a little to the track width.

How much does the wilwood brakes set the wheel out from the stock setting?

Which wilwood setup are you using?

Chuck, .38 per side. I'm assuming the DSE drop spindles won't change the track width. For the front Aero 6 with 14" rotors and for the rear Superlite 4R with 12.88 rotors. I had them swap out the calipers from what they show online to configure it for a manual brake setup. I received the rear setup earlier this week and hopefully will get the fronts along with the MC/prop valve kit before long. I ended up going with Wilwood because the appear to need the least amount of clearance for the caliper from the wheel mounting surface. Originally I was going to use the C6 brakes from Kore3 but noticed how much clearance they needed for the caliper. Also Wilwood appears to make a good product based on the posts I read and in looking at the rear set. I must admit Baer's look to be a work of art if I compare some of the Willwod pieces to the Baer pics. Especially the backing plate for the e-brake.

Originally I was thinking about hydroboosting (even bought and rebuilt an Astro van hydroboost unit and an aluminum mounting plate - will probably end of selling them) but then decided to go with manual brakes after reading quite a few posts on the topic.

I got the body and parts from the media blaster on Friday. Overall it wasn't too bad since most of the spots we already knew about. There were a few surprises though. We thought the bottom windshied channel looked pretty good but I'll end up replacing it. Also after looking at the trunk pan I think we'll end up putting a new one in since I'll have the inner wheel wells the mini tub inners. At times it's a bit of a tough call whether to patch or replace since most of the parts don't look too bad.

We put some metal prep on and epoxy primed all the parts to keep them from rusting. The metal prep was interesting because it almost look like it flash rusts.

Body doesn't look that bad. I love 67's. Keep up the progress.
I use a manual booster on my race truck. It slows me down just fine plus I don't have any clutter. I'll end up doing the same on my 65 build.
Mike, I was looking at your build post and all I can say is wow.... I wish I had your skills (and equipment)...

Hey Ted, don't cut yourself short. Your build is bad ass and from what I can see, I'm not doing anything you couldn't do :)
I'm going home for a week this Friday so, I'll get to see my 67. (This makes me happy)
I do a lot of skim reading so I may have missed it.. What are you doing for the rear and shocks?
