Topic: Re: What do you plan to do with your C3 this winter?
in Forum: C3 General Discussion
At the time the FITECH system was the "sweet heart" of the bunch. The Holley system came out after I bought so missed it by a bit. I've been told by some folks that the "self-learning" systems have a bit of trouble figuring things out at higher altitudes (I live at 9,200 feet ASL) but I haven't totally bought into that theory. I should probably buy a "TBFI For Dummies" book and put it under my pillow for a few nights to absorb some stuff, maybe that will help some.
Interesting color choice Bill. Looks good with the color fade on the hood.
Right about TBFI For Dummies! When I bought this '75 five years ago, I didn't want one with a computer, but since then I've put the TBFI and Holley's electronic ignition box in along with Vintage Air air conditioning, all of which have computers in them.
I'd like to get the system tuned on a dyno, but the closest one is a few hours away. I set the timing and fuel ratio in the computers, but I'm sure a professional could fine-tune it much better. On a cold day it is a bit cold-natured in the first mile -- not like an EFI system should be.

NO! Don't do it. A lot of life left in it yet. Gas is still available, electric cars are not what they claim to be! You can still keep it and buy a newer one, VETTE, that is!

I wish I had room for 2 Vettes. You know, the new C8 ZO6 is 80 inches wide. I measured where my C3 sits and if I parked that ZO6 in my garage, I wouldn't be able to open the door to get out.
Wouldn't mind having a C6 ZO6.
I have no use for an electric car.

Bill don't feel alone. Not a Corvette, but when I went into the garage yesterday my 1961 Norton ES2 motorcycle had a large puddle of oil under it. I did not notice the puddle before yesterday and it was oil tight all summer. The only difference was that we had below zero temperature two days ago and the garage is not heated. I have no idea why that would cause it to leak the oil. I'll need to wait til spring to check it out.
Is there a chance that there was some water in the oil, and freezing caused it to push the case apart a bit?
Hi Bill,
Better late than never, I didn't see your response until today, go figure.
The engined wet stumped and the oil came out of the weep hole for the main bearing on the drive side of the engine. I drained the oil tank this winter so it won't happen again. Thanks for your idea on the subject.
This winter I'm having the interior renewed along with body mounts and the suspension rubbers replaced. I'm having a restoration shop near me do the work because I don't have the ability to lift the body for the body mount replacement. The rest of the work will save me time next summer so I can drive it more. Besides it is in a climate controlled environment for this winter.
Did you check the fuel regulator, many of the fitech's were sent out with 3 bar instead of 4 bar regulators, I had to change two units to get them to work correctly as the injectors are 4 bar. Good luck

I plan to get the parking brake working. Of course, first I have to get under it and see what parts I need to order. Real soon now...
I'm new to this site/club. My mostly original 327/4sp convertible '68 made a noise and quit running. So I might be doing a lot to it this winter. I have it at the shop where they will advise whether it just needs a bit of attention or maybe I am looking at some bigger decisions. I always thought if the original engine went kerplunk (that's what it sounded like) I would consider my options. I am considering what to do when I get the diagnosis...rebuild the orig 327/300 and keep it as much of a survivor as possible (never been graded), follow my teenager still in me (part of the reason we all play with these things) and go with a 383 stroker/new 5 spd gearbox, drive axle etc and throttle body fuel injection, go with that same line of thinking but add significantly more to the budget and go with an LS conversion, new 5 spd gearbox, etc etc etc. I can help but hope a little bit that the oig therw a rod, cracked the block and I am forced to make some "more power" decisions. Has anyone got any feelings/experience about the Holley throttle body injection system vs full on LS conversion???
Signed...torn between my budget and more power
