LT-1 Owners in forum

Hi, I'm a new member and I wanted to tell you a bit about my LT-1. I don't have an original LT-1 car, it's a 69 coupe that I built the motor to 70 LT-1 specs, using a GM LT-1 cam, 2.02 heads, and 11.0:1 compression. I use the car strictly for autocrossing, and I love the motor. I'd like my next Corvette to a 70 or 71 LT-1 convertible, so that I have one to cruise on the street.

Just checked and it has been quite awhile since I last posted here, anyway I completed the 383 stroker buildup of my original engine and am putting out @ 490 hp. I went to the track for the first time ever and on my 3rd run I had a 12.46 # 116.2 mph. I haven't learned how to successfully launch yet, maybe I will go once or twice next year. I have 245 15's BFG T/A's so I had to be careful shifting into 2nd and 3rd as well. I keep all my original parts, and will be adding the C5 seats that I just picked up as well as stripping and re-painting late winter/early spring.

GDH; Did you do any beefing up on the rest of the drive train & suspension? Or is the stock/original componments doing the job for you?

Hi, everyone, I own a mostly original 1971 LT-1 Roadster, Sunflower yellow, black interior, less than 40K original miles. Only option is the Delco AM/FM which I just sent out and had the volume control repaired and the radio cleaned. Presently I am having the breaks, bearings and rear springs replaced and the radiator repaired. I've only had it a short while, but love to drive it. I also love the sound of those lifters, and without and power options of any kind, its one of the few cars I've owned that you have to drive.......it doesn't drive you.

Happy new year, everyone. Pray for good weather in the northeast so we can get out on the roads before summer.

Hey everyone! Thought I'd better get on here and share some info on my car. I bought it in 1993. It had just been repainted Mille Miglia Red. Everything else, other than the starter, alternator, and distributor, was original, Since then I have had the engine rebuilt, rear end (3.55) rebuilt, new carpet and seat covers, new rear spring, and most recently, installed adjustable poly strut rods. Oh, I also had a new top put on shortly after I got it, and also have a hardtop for it. It is a fairly early car (#3081) with late August date codes, but a December build date, due to the strike that fall at GM. When I had the engine done, it was completely to stock specs, although they did some mild port cleanup on the heads, and it dynoed out at 386HP.

Oops, should have stated first- it's a '71

Well, better late then never.

I have a 72 LT-1 factory A/C car (only 240 built as I am told). It's heavily optioned with power everything, T/T wheel, A/C, AM/FM ( I added a CD changer). Sunflower (bad name for a vette) yellow with a black interior. The numbers match. To date I've done the following mods:
Headers and Flowmaster
New calipers and disks
New springs in front and composite in back.
Off set trailing arms so I can stuff 15 x 10 wheels.
Torque thrusts all around.
Hurst comp plus shifter.
MSD Ignition.
New harmonic balancer.

The car is a 10 on the 'grin-o-meter'.

 

[LIRacer]

ANyone every think about a 1970 -1972 LT-1 only meet?

 

[LIRacer]

I read an old post from JMP about the left hand mirror tilting at 70+ mph. That happnes to mine also. I spun it around so the shorter side is up and the problem stopped.

 

[tonyk72]

Count me in...

'72 LT-1
Red on Saddle Vinal
PS, PB, Tilt/tele
5600 Redline and 3.55 gears = A/C
Mostly all original except for alternator and a few other small items.
Also, one of my buddies told me his brother has a '70 LT-1 motor just laying around that he wants to get rid of...guess where that might be going...

 

[LIRacer]

Does your friend with the '70 LT-1 motor want to part with it?

 

[tonyk72]

Yes, but it's already slated for my engine bay... My original LT-1 is going to be tucked away for safe keeping.
All I gotta do is pick it up, not a bad deal I'd say!

 

[LIRacer]

Now why would you want to contaminate a '72 engine bay with all that extra HP? Dont you know that less is more?

Enjoy it.

Hello all.

I own a '72 LT-1. I've been researching and trying to find out about my motor which has a CRT code. It is the original motor and was the #85 car built for '72. I've not learned anything absolute about the CRT code except that it's specifications are listed the same as the CKY code, but having uncertain usage. Anyone have any ideas?

 

[69autoXr]

CRT Engine Code

Chevrolet By The Numbers 1970-75 lists the CRT code as 1972 Corvette 350, 255 hp, 4-speed, mechanical lifters, Holley 4-barrel with A.I.R.

 

[Billy]

Thanks 69autoXr,

Those are the same specs as the CKY, so still I'm not sure what differentiates the CRT.

 

[GaryS]

According to the NCRS 1970-72 Judging Manual "Chevrolet service records list CRT...code(s), but Flint and Tonawanda report none wer produced. Their existence is unverified." Since you have a very early car, probably built on the first day of production, why don't you write me off line and I will send you the email address of the editor for the NCRS Restorer magazine. He has started an LT1 survey that is ongoing despite the fact that it has been around for several years.

My LT-1 info

I just found this site and forum. . .

I've got a 1972 LT-1 Air Coupe in Sunflower Yellow with pretty much every available factory option.
Delux Saddle interior
Power Windows
Power Brakes
Power Steering
Tilt/Tele wheel
AM/FM Stereo
Rear Window Defroster
Air Injection Reactor (still installed, no less)

The car was sold in Souther California by a dealer who did mild custom work. In this case it included side pipes, custom wheels/tires and a custom paint job (the rear is white reflective (imron?) paint). Aside from closing off the tailpipe openings the car has a stock body (no flares or anything).

The Vette is otherwise a stock, numbers matching, well documented (window sticker, protecto-plate, maintenance records, etc.) vehicle. I'm the second owner (since around 1989) and I've added only a few miles to the current 104K total.

The car is tons of fun to drive and is a very tight, clean unrestored example.

I'm still trying to decide if I should kill the custom work and bring the car up to NCRS standards or not but for now it's an occasional cruiser that can set off car alarms just by driving by.

Erik,

Which sidepipes are on it?

 

[Erik S. Klein]

The car has the stock for 1969 C-3 sidepipes.

Erik

 

[LIRacer]

I am putting on a set of 4 inch hooker side pipes.

 

[Erik S. Klein]

I've still got the original cast iron exhaust manifolds on the car so anything I improve on the exhaust system would have to start there.

I had a base-motor 1972 a while back and tricked out the performance tons over the time that I owned it. Besides a fairly performance oriented 400 motor (lumpy cam, dual plane intake manifold, etc.) and a shift kit in the TH350 I had a nice set of headers and performance mufflers on the car.

I had also reworked the suspension with a 'glass leaf and performance shocks, springs and sway bars plus urathane bushings all around.

The car cornered flat and went fast, at least for a while.

I like the fact that my current car is closer to stock even if it isn't as exciting when you put your foot in it. To make NCRS judges happy I'll have to lose the sidepipes, wheels, luggage rack and custom paint. That and a bit of cleaning and I'm probably pretty close to a second flight car.
