Looking at it with a magnifying glass my bet would be a nine.

Doesn't look like a 0 in person. Just thought if the  car was out there with a number like that they might want to check it out. Not worth anything to me.

Have had this case laying around the shop for 30+ years believe last digit is a 9. They struck it twice last digit not too clear.

Thanks for the response. I'll reuse mine

I purchased a new NAPA (Gates) lower radiator hose for my 69 small block Z-28, it has no spring in the hose. Did factory hoses have a spring? I've always thought it helped prevent collapsing from suction.

Let us know how it works out, thinking of the same using the same one

Who makes the best correct stripe stencil kit for 69 Z-28?

I'm a little confused with the 52 degrees total advance (vacuum plugged) referred to in one of the earlier posts. For distributer part #1111480 69 manual calls for 32 degrees total centrifugal@ 4400 RPM. Add 4 degrees initial total would be 36 degrees total with no vacuum. Am I missing something?

I clamp vise grips on the tubing wrench to help keep it from spreading apart. Often helps on a tough fitting.

Ignition is stock distributor and coil, plugs are 44 Autolite, 36 total advance. Compression is 11.1, the combustion chambers are a little big, came that way from factory, and I wanted to run a composite head gasket, so I had J&E make pistons to my specs.

Rebuilt my 69 Z engine this past year. Been in the car for 35 years and I decided to go through it. Only variations from stock specs are .040 overbore, 3927140 off road camshaft, stiffer valve springs, 69 GM crossram, and 1 5/8"primary 3" collector equal length headers. Best numbers were 370 lbs. torque @5700 and 417 H.P. @ 6700.

Right in that 1976 timeframe I went to look at a Z-28, engine out up side down on the carport floor with a bad crank. Car was silver, black stripes, radio delete with 30,000 miles showing. Had a few scuffs wasn't a garage queen, passed on it at $1400.00. Like to have that opportunity again.

I stripped a JL-8 car in 1976. Car had had a very rough life totaled and rebuilt, then wrecked several more times. My brother and I bought the car for $1800 (borrowed the money from our Dad). I thought I would put the rear-end in my Z and sell the car, then I realized the whole front set was different. So I pulled the cars nose to nose and took everything down to the master cylinder. I took the brakes, my brother swapped the trans, heads and intake for junk stuff and we drove the car to Seattle and sold it to a dealer for $1800! Still running the brakes, long story, but shows how different times were.

Jon were there any modifications allowed, head porting, compression, etc? I've read that top teams made power in the 450 range, good #'s for stock stuff.

I was thinking higher on the low side with a four speed they would have wanted to keep up in the power range. Just a guess haven't ever done that type of racing.
