You are very handy and have alot of know how on different repairs and projects.

Are you a veteran automechanic too?

I think I read some of your older posts where you also worked in a custom performance shop and/ or a speed shop?

I believe you.

You have a few years at it more than I do.

Been at it hard since 1983 when I was 14 years old.

Go karts, mini bikes, Briggs & Straton and Techomash 1 cyl motors before that and getting chased by the local police for riding them on the streets.

Again and again. lol

I used the 1.6 complete kit that ecklers sells and bought the springs that they also sell at the same time. I didnt go full roller but with the roller tips, didnt want he extra noise and this is just a daily driver. something that may help others is that I removed all the rockers at the same time and with an air hold didnt worry bout the engine turning, take a 1/2 socket and tap each spring to loosen things up, It saves alot of time. I put both o-ring and umbralla seals on all valves,had to buy two sets but its money well spent. I had good compression and I mic'd the valves from the top , its not as accurate as doing it from the bottom but it gives an indication of guide slop. Due to the milage on this car, i also replaced all the injectors with FIC 3rd design bosh. the only thing I did with that that some may not do is I removed both plenum and runners instead of just loosening them, its a little extra time but cleaning gasket surfaces and actually seeing whats there is a good way to insure everything is good with no leaks. I've never done non-commision mechanic work, so having to do something twice only costs money and loss of customers . It runs excellent , and I am happy with it.

I know that feeling. When I'm on edge it always seems to come out on the wrong person.

The fun of driving the car with the new mods always makes the pain of the install go away.

I'm sorry I still dont have pics of this but I thought I'd give a small update. With only the above mods I went on a three hundred mile trip for a test run. My mpg went from 21-22, at 65 mph average speed, to 24-25 at 65 mph average speed. I'm very pleased with it. More fuel milage and more driveability. I installed the fancy shifter and then removed it. It worked fine , I just didnt like the looks in my stock interior. In a race car it would have been fine.

Its still a ton of fun driving a C4 on the street.
Something that can be hard to do after you turn any car into a pure track car. Especially with today's rising fuel prices.
Word is I am hearing is that pump gas is maybe going to $5.00 per gallon here in the midwest by mid summer. That is for only cheap 87 octane gas.
None of us really like running our C4's lower than 91 or 93 octane.
Especially with performance tuning and engine mods made.
What have you heard out on the west coast- California?
What style or brand shifter did you install in your 87 Vette before you took it out?
Take your Vette on a real long trip say 900 miles each way.
You will have even more fun driving it and exploring the USA.
I did that back in fall of 2008 with my 87 vert.
Lots of fun and memories.
For the wife back then too.
We were together not for long when we made the road trip to Her hometown Reston, Virginia.
Her 20th highschool reunion.
She was worried that we would not make it in time.
We did.
The hammer was down.
And my eagle eyes looking miles ahead always.
Drove 10 hours straight before we had to stop. Drove through Friday night into Saturday Morning.
19 hour trip one way I remember now too.
Made it in about 14 hours of driving time on the road
No breakdowns.
Averaged about 27MPG the entire trip. Driving fast.

Brian

The shifter was, or I should say is a stealth pro ratchet from B&M, as I said it worked fine , just not what I wanted in my 'stock' car. It'll probably make it to the 'for sale' section. Gas is $4.50 range out here, I run 87 octane in my 87 without any issues, and I run injector cleaner thru every 4-5 tanks, with the new seals it no longer smokes or uses oil. One thing that I did learn is that the small screw on the wiper board cover, thats a pita to get to if you forget to snug it up is the ground for the wiper board. you'll need it snugged up when it rains or you'll have intermittent wipers when you dont want them and you wont like them.
