Re: 67 Z28 project
 

Since the original engine is gone the CE would be okay, but since you have an experimental AL laying around (don't we all? https://www.yenko.net/ubbthreads/imag...arleySucks.gif ), I would go with that one.

Re: 67 Z28 project
 

Charley what is the story on the aluminum motor? It looks like it has bolt holes on the ends of heads for the later style alt. brackets. How about running this with a very early cross ram and a cross ram cowl plenum air cleaner set up? I do not see how this could be any tricker. It would be like the semi hemi yellow 69 Z/28.

Is the AL X-motor a 302?
What did the AL blocks in the Grand Sports look like?

Re: 67 Z28 project
 

Aluminum parts were acquired by someone in about 72. Maybe they fell off a truck ? I was told Jack Podell also had a set of aluminum heads like these that he used to have for sale. They also had the bolt holes but were from the 60's. Mark..Would you now hook me up with a early crossram and early crossram cowl plenum ? It is starting to sound like my old 67 RS Z with the Xram.

Damn Charley!!!!

I can find stuff, but YOU...

You can really find things I havent seen before!!!!

Would LUV a nice detailed write up of that motor!!!

No 0-code for that block.

Is it dated????

Any similarities to the 0-code Can-Am blocks, etc that were prototyped???

That's a first for me on a SBC Intake with this coding!

Re: 67 Z28 project
 

No dates on the block, just the 366298 #. The block was virtually a raw casting with only pan rails machined. Apparently when a block is machined they start by doing the pan rails and reference everything else from there. The block has traveled all over the country having stuff done to it. It is a very rare Dude.

Re: 67 Z28 project
 

Anything similar to the ZL1???

I recall the Delta Bolts on the main caps on mine when I had it.

Any external blockside stampings that distinguish this relative to any GM aluminum motor you been exposed to???

Re: 67 Z28 project
 

It looks like a GM bowtie block and has a bowtie but they use a small diameter truck type oil filter. This is cast for a full size one.

Re: 67 Z28 project
 

Seeing as it's original block is long gone,I would opt the experimental SB alloy & use that cowl plenum AC.That would be killer!

Re: 67 Z28 project
 

I overheard a guy at work (I work for GM) talking about aluminum SBC blocks that were cast in the late 60s for the Chaparral cars. In fact he built a gorgeous replica with one of these GM aluminum SBCs, I think a 331 or 377 or some other high winding deal. Will see if I can get any more info out of him.
