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.

My build is a 1967 302, which did use a 657 2 bolt block as I have, my heads are also 462s the only difference between my block and an original 302 block is the code on the deck. I did sonic ck my block after cleaning, I think it will be ok, hoping for 400 HP on the dyno.

Pictures of rods. I will balance them next.

Setting up for the line hone.

Nice progress.

Are you building for street or strip ? Higher quality rods would be a good idea. I have spun my Original 69 Z28/RS to 7200rpm on many occasions, but that is playing with fire. On one of my 302 engines in my Super Stock car I have spun it too well over 9000.

Today I finished my line hone, set housing bore to 2.4914. Next I will clean the block and set up for decking, assembly height:

Stroke 3.00
Rod length 5.698
Comp height. 1.800
Total height. 8.998

I need to decide which head gasket thickness I will use, then I will cut the block.

Mike Jones you are doing a fine job, keep the Build updates coming. It's great to see a young fellow developing an ability. Your combination of parts should workout just fine, keep it light and low drag. The preparation of all the components are important, but you appear to have that handled. Keep up the "GOOD WORK"… Maurice.

Thanks! A member on here donated this 1967 small journal Z/28 windage tray, which was very appreciated, very hard to find piece. I will clean it and punch the holes out.
