For 1970, a new forged-steel crankshaft was used with drop-forged steel connecting rods.
Forged-aluminum 11.0:1 pistons made by TRW. Fitted with a dual snorkle Smog cleaner.
My build date is 05E which decodes as May 5th week.

They are not 1970 Z/28 specific so it might help those who are looking to look at other 1970 Camaros besides a Z/28.
A 1970 307 cid-T350 Camaro used the same rad as a 1970 T400 Z28.
Look beyond the Z28 mentality and you might find what you are looking for.

Overflow jugs were not used in 1970, but you can add one.
Without an overflow jug
With an overflow jug. Make sure the arrow points to the tube or the water will not drain back into the rad.
GM EOS 992869
AC Delco EOS 992869 contains 6221 ppm of ZDDT and 5762 ppm of Phosphorus.
Oil I use with enough ZDDP to protect the flat tappet engine. I do add 1 bottle of GM EOS with the Valvoline oil.
Joe Gibbs Hot Rod oil does not need EOS. If you add anything it will disturb the chemistry.
I started to use ZDDPlus to non synthetic oil to be better on the pocket book.
GM stopped selling AC PF25 and PF35 oil filters which did not have the anti drain back valve.
Napa Gold 1061 is the replacement for the PF35 oil filter and it also does not have the anti drain back valve.
SB and BB Chevy's already has an anti drain back valve in the oil filter spin on adaptor.
Break in your cam with Joe Gibbs BR Oil, Viscosity typical of SAE 15W-50
Wiped 3 lobes on the solid lifter cam due to lack of ZDDP after about 43,000 miles. It was a slow wear.
Pic on the right, shows the 1st lifter (2E) good compared to the other 3 concaved lifters.

To change the cable at the inside rod end,
Laying on the carpet, squeeze the back of the plastic lock and push it towards you and it'll pop out.
There are slits on the back that compress so it can come out of the hole frontward and locks into place
when you push it back on. The plastic piece has a slit in it so the cable can be slid out and the new one
slid back in.
