Ok I wire brushed and WD the block to see the casting numbers Had a neighbor look also to make sure .I first thought it was a D9 but he pointed out the curve in line not straight like the other D . Lots of rust under the blue paint they just sprayed to cover up years ago I guess . Know the guy I got it from said he pulled it from a 82 Squad car he had .
It has a aluminum 2v intake on it with a date of E1 for 1981

Block is cast C9AE 6015 ED-15
Date 2A5 -- 1972 Jan 5th

Exhaust manifolds D00E-9430-D right side the left the number are the D00E-9431-D

Cant wait to get it on a stand and pull the heads for numbers . That will for surely help out . Hope its the bigger valves .

Well, the D0OE manifolds are encouraging, let's hope the heads have those #'s too, they're the good 'uns. Cop cars often had the older, better performance stuff. I have just about the same car at a buddy's place, haven't checked the numbers yet.

Bobby - occasionally you can find the head casting number when you pull the valve covers. The last set of D0OE's that I scrapped were that way (they wouldn't sell after several years worth of occasional listings on eBay, Craigslist and at swap meets .... and I needed the room)

If the block is truly a 69 cast block, the deck heigth ia 9.480. '72 on, it was increased to 9.503.
This is something to remember if internals are being replaced.

Thanks guys for the reply's you know the internet info varies so much that some info is different from page to page . I did pop the cover and no # other then 1K30 and a 78 . Read somewhere about something of the springs having machined surfaces these look done ?? . Couple pics of heads they will be off by Friday morn . Then we will no and maybe I can get a better view of block casting instead of standing on my head .

Bobby - with bolt down rocker arms, I really doubt that you have the big valve heads, but the D7OE-DA OR D8OE-AB. If they are the economy driven-shrouded, 69cc heads, you might be best off to either go with after markets or spend some time looking for the D0OE-G or C9OE-B / D or even some GT40s (the GT40P is widely available)

Dave thanks not really going for a power house but if I run up on some cheap I'll get them . I will make these work or check out the salvage picks for some better one's later on . Some early 70's seem a bit better to If I read right .

What he said. Rail rockers mean they're not the good heads.

LOL back to the drawing board .

Thanks Dave. Good size for the street and reasonable RPM..
