Figured I would give an update to the project. Ran all new SS brake lines and put new calipers and brake pads on. I planned to restore the calipers, but they were in super rough shape.

still need to tie in the front calipers to the brake lines. Also put a new master cylinder on.

Just to get an idea of the shape of your engine I would do a compression test and check the color of the spark plugs. If it has a lot of miles it might need valve guides and a bore.

I had good compression on my 82 but the heads were shot so I opted for a Blueprint crate motor.

Wouldn’t start today and found the battery drained. Must have something on somewhere, but hard to tell with so much torn apart, but made some really good progress today.

Brakes are bled and ready to go.

found out the engine temp gauge doesn’t work and found a leaking radiator hose.

I did get some new tires and rims off FB marketplace to replace the set that was on it. Installed in 1984



Headlights were the only bulbs not blown, so picked those up this evening.

Getting really close to getting it back on the road.

I see it has the two tone light/dark buckskin interior. I have the same one in a ‘76, but decided to change it all to the lighter buckskin color. If you’re curious they do make carpet in the lighter color.

I believe that is doeskin. Interior.

Gave it a sponge bath today since the windows don’t roll up yet…more of the bumper fell off.

Put the hood back on and still need to align it.

Is there a way to have this thread move from tech/performance to general?

I'm thinking maybe the understatement of the year, decade?lol I was going to chime in earlier on this post, but it looked like you were excited and having some fun. I am just going to come out and say it (coming from 30yrs of C3 ownership). Pls do yourself a favour, unless you are an expert C3 restorer, it will cost you 3X as much to get that "vette" to the point where it would be comparable to a good C3 "driver" you can buy anywhere. They are still relatively inexpensive and I have seen this same scenario play out many times. Believe me when I say I am just trying to help.

As for C3 motors and their "valve guides" ---
ALL OE C3 IRON heads (sbc & BBC) have Integral Valve Guides (cast in during casting pour).
Replacing guides in those heads is expensive; although the parts are reasonable, the labor is crazy expensive (entire guide has to be milled away) AND there's great risk of cracking head as new guide is driven-in.

In lieu of guide replacement; today's bronze "Guide Liners" are typically preferred. They're even better than new and their purchase & labor are much more reasonable.
Top names in Guide Liners are K-Liner and Golden Bullet. Not ALL shops have the tooling for Guide Liners; call ahead. Installing Guide-Liners is NOT for DIYers.
