Wal-Mart stocks CD2 brand lead substitute. I was using this stuff for a couple years on my 68 Merc's 390, and never had problems with it. Can't verify that it actually does what it's supposed to do though, & I'm not going to take the heads off anytime soon to see either. Just from past experience with their products, they make good stuff. The bottle has a "dose" chamber and directions for use. The whole bottle treats about 350 gals. and cost's less than $10.

So I do need it for my 289

It depends. what year is your motor?
If you have a 60’s engine that has never been rebuilt then you should run some from time to time. If your heads were rebuilt with hardened valve seats then no.
If your engine has never been rebuilt it must be close to that time. I am assuming that a 40 year old stang has some miles on it if it’s all original.

I wish I knew what year the engine is of if it has bewen rebuilt. I got the car a couple of days ago and all I know is it got a new tranny last year

PMUM5 is correct. If you have none hardend valve seats like in all early engines then you should use it or the valves will wear into the seat and ruin them. If you have had your heads rebuilt with hardend seats then no you dont need lead. you dont need lead with any aftermarket heads.

 

[Fireman255]

so if I don't know, would it hurt to use it if it has been rebuilt?

Better to be safe than sorry........ if in doubt----- use it.

No, lead itself isn't toxic. Lead fumes and dust are. And where did I tell him to use a lead additive? Plus, the amount of lead that one car uses to keep the valves lubricated isn't enough to harm anyone, unless he/she has their mouth wrapped around the tailpipe and is directly inhaling the exhaust. In that case, the lead isn't what's going to kill you, the CO is going to do the deed long before the lead ever will.

lead is toxic. Installation of lead pipes in ancient Greece and Rome wiped out whole settlements. anyhoo... Now-a-days CO and cigerettes will no doubt do you more harm than the amount of lead around now but its still bad for you.

There were and still are lots of century old houses here in the US that have/had lead pipes and you don't hear about wholesale deaths because of them. Lead is bad for you if ingested in large quantities but minute amounts are relatively harmless. I used to cast huge quantities of lead bullets and I'm still here. Of course I do occasionally suffer from "CRS" sometimes. Don't know if it was from the lead or "other" substances I used to ingest 20 something years ago.
