William,
go to Classic Industries web site and type in part number "L95" and take a look at that book. I have a copy and it is VERY basic and inexpensive. Only 100 pages and just enough detail and pictures to show you what is involved and what you would need to do. It would be good for a first restoration book but not really detailed enough to do a full high end professional restoration. Just a "Restoration 101" type book. Pictures make all the difference.

Hope this helps,

-Mark.

That depends on what you are trying to do. There are factory assembly manuals, numbers books, and chassis service manuals. There isn't just one good manual. You will need a custom set depending on your needs.

Thanks again...I assume 291's that came with 2.02's had the unshrouding done at the factory?

All of the "double hump" or "fuelie" style heads that were originally factory fitted with the larger 2.02"/1.6" valves will have the intake valve unshrouded like that picture John posted.

349  Camaro Research Group Discussion / Decoding/Numbers / Re: Help on date coded block?? on: January 24, 2010, 04:59:10 PM
You are comparing the assembly date of the engine, as is mechanicaly stamped into the block, to the body build date shown on the Fisher Body trim tag. That means the engine assembly stamp was on average about 2 weeks before the body began assembly on a Z/28 that was produced during that time frame where your car was built. You will find some cars with dates closer and some that are farther apart because there was no "first in-first out" type inventory control. They were basicaly building components as fast as they were selling the cars at that time so there was not a lot of extra stuff laying around.

You can purchase old DuPont paint catalog pages from dealers that specialize in that sort of thing. I have a set for '69. They are not that expensive.

If we had a reference picture of a car in each color that might be a worthy addition to the CRG site. I know there are plenty of pictures out there.

After running the "30-30" for some time in my 302 I tried a Crane F-278-2 and that one worked a LOT better in my opinion. I don't ever think about switching back. It has about the same opening / closing points and wider lobe separation as the LT-1 but it has more lift. If you try to find another grind with those characteristics "on the shelf" you will have a tough time. The other solids available are all too narrow or too big.

Availability might be a problem right now but you have to think Crane camshafts will come back at some point soon.

30cc is the one. The 50cc was originaly OEM spec'd for a REO Commercial Chassis (Firetruck) but it is also used on aftermarket applications where racers need a huge pump shot. I doubt it has any OEM car applications.

I do not believe that a "documented" list exists. I am sure CRG would not publish anything we have sent in either. The info we send in should be confidential and is only as good as the sender it comes from.

355  Camaro Research Group Discussion / Restoration / Re: Rear end sits too high on: January 10, 2010, 10:47:14 AM
Did you lower the car to the ground before you tightened the rear leaf spring bolts ? If you did, loosen the bolts  and lean on the bumper a couple times and then tighten the bolts. some people tighten thos bolts while the car is up in the air and then the rubber bushings are holding the car up.

Do that after you have it all assembled. You need all the weight of the car to be on the springs before you tighten the bolts. Smiley

I was under the inpression that the trim rings with (4) rivited steel grippers attached to the back were correct sttyle for production but there are rings out there that were used later years on other models and in service that have the sheet metal full circumference retainer on the back side. I can't tell the difference without pulling them off the car.

You can add some close replacement rivits to your sill plates if you want.  I bought some of these rivits a few years ago and installed them. They look rather good if you ask me. Let me know if you want to see a picture. I think I have the guys email address somewhere. They don't cost too much. I know he had a BUNCH made at the time.

Pump adjustment is the first thing that comes to mind.
I am with Steve.

You must not have ANY slack in the accelerator pump linkage AND have about .015" ADDITIONAL travel available on the pump arm with the throttle open all the way so you do not bottom out the accelerator pump when you floor it to WOT.

What color accelerator pump cam are you running?
