Can anybody ID this engine?

This was in an old service car (kind of like an informal hearse). What the heck is it? I can't figure it out.

 

looks like a ford to me with an hei unit. but i could be wrong?

 

Olds or Pontiac

 

Looks like a Buick 400-455 based on the front dizzy and the collant inlet/outlet locations to me...definitely not an Olds, but the valve cover bolts throw me off??

 

Buick 455:

 

How come you never see any of these used in a hot rod? I suppose there are, but not that I have seen.

 

Olds 455, dizzy in the back:

 

I agree looks like mid 70's Buick

 

I thought it looked like a GM engine but I didn't have a clue what. The dizzy told me mid-70's. Thanks gentlemen.

 

yea i knew i was wrong!

 

Yep def. a Buick motor.

 

Since when did Fords come with GM HEI units???

 

X2. EGR valve shows it to be 1973-up.

 

Looks like the old 430 Buick my mom used to have with HEI ignition added.

 

buick!!!! I have a hard time tellin small block and big block buick apart. If it was in something big I would assume 455.

400 1967 -1969

430 1967-1969

455 1970 -1976

 

Ya its a buick, the valve cover show its not an Olds

 

I,m gunna say 350 buick, 455s arent really very big though.
but 350 is my final answer

 

455 Buick...

 

1975-76 Buick 455. Earlier ones were red from the factory.

 

Looks like the 455 in my wife's -aunts 75 Electra

 

call me crazy, but i have seen it!

 

looks like a buick 350 thats in a 1963 jeep pickup for sale at 623-695-6031. call for details

 

I vote Buick.

 

Looks like a buick. Look at the pictures of them on google images.

 

+973 for Buick, although I can't say for sure what size.

 

Case closed it's a 350ci buick.
