I drove it for the last two summers, once up to Bowling Green for the CI and to a few out of town drag racing events. Currently the car is stripped for paint and a few upgrades.
Got to stay the fastest, with all these supercharged C-3 in the works. Once Monty get his going I'm out.
Last year I ran a T-56 with 3:55's. The problem with 3:55's is you are lugging around on the highway at 1700 rpms and only doing 78 mph. I didn't care for that to much. Thanks to a trade on the forum and Traccdog2, I got the back changed to 4:11. My cruise rpms should be around 2200 now.
Your going to like the LS1.

I appreciate everyone's info...
I still have a part of me that says go for the LS engines, but then I have another part that tells me to rebuild the engine and a fuel injection set up...
Have any of you or any one you know ran the original SB and with a hi perf. cam and an electronic fuel injection setup? How is its reliablity, throttle response, and it so on....
p.s. this doesn't mean the LS is not an option...

My last motor i had before the ls1 was a 360 ci zz4 roller cammed world products sportsman 2 heads tpi motor.You could always build up your motor and add a modified tpi setup,i got 22 mpg with 3.70 gears.There great for low end torque just not the greatest for high rpm use above 5500.Unless you spend alot more money for a superram.

JK!1973 Corvette with a dark blue metallic ( is that your original color?), that had a TPI and now has an LS engine..
That is exactly what my car use to be and will be put back to in the future! It was originally a dark blue metallic, with the blue interior ( It's been converted to black and like that it will stay)..
I guess, I'll have to get a fuel injected BB!
Just curious, what options came with your 73 originally?

Well I guess they are some what different... Good looking car! Nothing grabs my attention more than a '73! That might be because they are different from all the other C3's

I put a ls1 in my 73 roadster about a year ago. I love driving the 73 now. It has about 140 more horsepower than the L48 and gets 18 in town,24 on highway. It cost me about $6000 and I did all the work myself. The best part is going to shows and watching people check the ls1 out.I get asked all kind of questions . I checked your profile and I see you are are from Illinois. What city are you from? Here are some photos of My vette.

Hey buddy,
I believe your car and I have met before...
I am from Rochester, Ill...
I believe you attended the Swapfest at mid-america this year? and did the autocross?
You have a nice looking car!
What all have you done to it?

OK TOTOP73....You are my hero. I just got my LS1 yesterday. It's still in the back of the truck. Like you, I'll be doing all of my own work. I have a boat load of questions for you. I'd like to PM you and exchange info and maybe give you a call.....Glenn P

Yes, I could just sit and look at that C3 body all day. The wife, now that's another story. I have to move all my stuff tomorrow.
If you're ever in San Diego, look me up....gp

I'm in the early phase of doing my conversion and it looks to me like different vendors have solutions to different parts of the puzzle to make it all work. For example, I'll be going to Jegs for motor, trans mounts, speartech for wiring harness conversion, local shops for drive shaft, AC update, etc. I don't think that there is a universal "Kit" from one vendor. I'll be documenting every step of my project and I'll keep you guys posted. The photo's that TOTOP73 posted are a major inspiration. How can you top that for a C3? By the way, you are Ca. smog exempt so if you decided to do yours, it would be MUCH easier then the 76' I'm doing......GP

Pat....I hope I'm not hijacking this thread. I'd like to talk to you off line about your swap. I send you a PM to get your info.
I have the entire under hood harness from the donor car. Most guys who do this conversion don't have to worry about having all the original donor car smog equipment operational in their project car. I'd bet you were able to delete most of the smog sensors in your computer. I have to have all the 2002 smog sensors working in my 76'. This means adding a tank sensor (whatever that is) and who knows what else. That's why I'll probably need some profession help with wiring. Getting all the basic stuff operational should be too bad.....gp
