Default 302 Chevrolet Engine Build

I've always been fascinated by first generation Z/28s, which brings me to my first engine rebuild, a 1966 October 657 casting block with matching 462 casting heads. I will post pictures as I go along. The first pictures show the core cleaned along with the block prepped for machine work which I will start this coming week.

Is this a restoration type project?

No it will be dyno tested then put on a cradle until I get a car. The machine work starts today.

If you are building a race motor, you probably should consider different rods.

Why are you starting with a 2 bolt main block, 302 came with 4 bolt? The original blocks where 618 castings in '69. I'm not questioning your build, just pointing out different items, but in 1966 maybe they used 2 bolt blocks.
Also, if you are using an older block be sure to test the walls for pin holes. I personally got burned by the pin holes twice.

Thanks, but I have a crank. I will have it ground and indexed, and the stroke will be set at 3".

This is my first over haul, I hope to race, but I will keep the RPM around 7000 RPM, I will be running a light piston with a low drag ring pack. There was a guy that came around my Dads shop that bought a new 1967 Z/28, he said he buried the tach every day-anyone else ever heard this story?
