Re: LS-7 Motor??? On ebay
 

Dont know if this questions been asked but is it safe to assume all LS 7's are stamped CE on the pad or how did they did they handle that? Just wondered [img]/ubbthreads/images/graemlins/dunno.gif[/img]

No, I believe they were stamped "XCH" or something like that.

Didn't the LS7 have 077 aluminum heads? The one I bought from Indy a few years ago had 077 heads and
a lowrise aluminum intake, 596 I think.
The one in the add looks to have rusted iron heads, and I don't even see the usual SQ port hump on the
front of the heads.

I think they came with cast iron heads. But, I'm not sure if they used the LS-6's 291s or the later service replacement open chamber "188" heads. [img]/ubbthreads/images/graemlins/dunno.gif[/img]

69L72RS,
I flipped thru one of my 70-71 engine books and it does say the LS-7 had aluminum/semi-hemi heads and a low-riser aluminum manifold.The title of the article is " The L/88 that can be lived with in the street".---JoeG

Came across the LS-7 head part # 3946072 ---1969 design

Re: LS-7 Motor??? On ebay
 

I asked the seller about the head issue, he replied that they could come both ways, alumunum or iron. I had always thought they had aluminum heads, I would do homework about this issue before I laid down the $$$$$ for this engine.

I purchased mine around `83 or `84 brand new Rob is correct with the "xch" designation! mine is right above the timing cover 1219 XCH nothing stamped on the pad ,iron heads, this at the time was leftover shelf parts

Re: LS-7 Motor??? On ebay
 

Kloneco,
Was the aluminum head still available then or did GM just offer the iron block on the later LS-7.--JoeG
