Any help is appreciated! The previous owner said it was a 72' truck but It has dual headlights and I didn't think a 72 had them.

 

Block was cast in 7/6 of 1988 and it is a 440 casting number.

7/5/1988,

 

That does not make any sense. Because the last year of it was 78-79 right?

 

I looked at the date closer and I can't tell if it's a 1988, 86 or 66 but the 6430 block is supposed to be a late block.

 

What would the .5 mean? Like a mid year

 

Month/may got it?

Thanks y all. I didn't know where to start. And I believe this truck was pieced toget her but I do appreciate it.

 

Alright fellers. I got you another pic but this one is the head. How can you tell which heads theses are.

 

looks like 906 Head casting ??????

 

Are they any good by chance. What I've done. I've jumped the gun on the built and now Im realizing everything and pretty confused. Plus with no knowledge on anything about it. But what I've thought about now is just going with a aftermarket head for street/ drag

 

aftermarket heads are a good step up.. Availability seems to be the biggest challenge's

 

I've done A little more research Nd they are indeed 906 heads.
