Thank you. Thanks exactly the information that I'm looking for. When I press out the pins I will measure the openings. Then
I will draw my conclusions as what to do for my restoration. How is the lubrication to the floating pins accomplished. Are they
under oil pressure or just simply splash lubrication.

Thanks for your comments. Some background on the vehicle. I purchased the car about 20 years ago from a gentleman
who said he was road racing the car. Though the engine in the car was not completely stock. I have verified numerous 302
engine components, suspension components, interior components and exhaust components. The engine has been dissambled.
The pistons are trw with grooves for wrist pin retainers. But the pistons are not stock 302 pistons. The connecting rods have
the raised letter 'O' on the bottom of the connecting rod caps. There are some numbers (3 digits) around the cap bolt bosses. The
question I have  did the 1970 LT1 Z/28 have connecting rods that had the raised letter 'O' on the bottom of the connecting
rod caps?

You are correct 70 LT1 engines used pressed in pins and used  large journal rods. The rods I have are also large journal and they have the raised letter 'O' on the bottom of the rod cap (69 z/28 rods have a raised letter 'O' on the bottom of the rod cap, 67 and 68 z/28 are small journal rods, dont know if any letters are on the bottom of the rod cap for 67 or 68). The gentleman I purchased my car from over 20 years ago informed me that he road raced the car. I'm trying to determine if my rods were modified to accept pressed
pins or may be 1970 LT1 connecting rods. The key question is that did 1970 LT1 connecting rods have the raised letter 'O'
on the bottom of the rod cap. If the 1970 LT1 engines did not use the raised letter 'O', then by deductin these are 69 z/28
rods, though modified.

I'm trying to find out some information regarding z/28 connecting rods. I have a 1969 z/28 camaro
that I'm starting to restore. Upon removing the pistons and inspecting the connecting rods I noticed
that on the bottom of the connecting rod end cap their were the raised letter 'O' which is correct for the
pink rods for a 1969 z/28. But, what has me confused is that the wrist pins are pressed on. My question
is did the 1970 z/28 camaro with the LT1 use connecting rods that had raised letter 'O' on the bottom
of the connecting rod but used pressed wrist pins. Or in my case did someone convert the full floating
pins to pressed pins?

John Z.  When I bought my 1969 z/28 about 25-30 Years ago. The owner who claimed that
he was road racing the vehicle threw in the trunk a few extra components. It included
a 15/16 front sway bar and two front coil springs with a tag that had the numbers
3935784. Do you know if these are GM off-road springs by the part numbers? And
could this be a gm sway bar?

Let me know if you find anything out. I also went to the Dupont web site. They have a historical color chip section for older paint
codes. Here is the link for Dupont performance coatings.

Let me know anytype of information. I will be contacting my paint person next week.

Thanks.

I am in the process of having the rally wheels on my 1969 z/28 painted to the factory colors.
I do realize that the silver color is called Argent silver. My paint man wants to know what
the paint chips are or the color mixing charts. He uses Dupont paints. I would appreciate any
direction as to identify how to mix the dupont paint in order to achieve the Argent silver
color.

My vehicle did not come with a grab strap on the right side of the dash, nor are their any holes for it.

John Z,

What does the Z87 deluxe interior consist of? The interior of my car has standard door panels, 7000 rpm tach, red lined
at 6000, floor gauges with console, shoulder strap seat belts for the front passengers, AM Radio, and clock in the instrument
panel.

Thanks again

John Z.

My 1969 z/28 camaro, build date of 1OD, with a flat hood. Had hood insulation as well as
a trunk mat. I know that for a fact because when I bought the vehicle over 20 years ago.
I removed the insulation for the hood because it was tearing and I threw out the trunk
mat because it was also torn. Does that mean my 69 was ordered with the z87 deluxe
interior. I also have the front endura front bumper.

Thanks
Alan

Is it considered a safe practice to sleve cylinders. My 302 block may have a sleve in one of the cylinders. I'm
not sure. But, I will be finding out shortly.

I am trying to find out what ignition coil came with a October 1968 produced
1969 z/28 camaro. Is it a 293 BR coil or a 298 BR coil.

Thanks for any information.
