dodge28 Posted August 5 Share Posted August 5 I recently saw on yutube a Pontiac (50's) with a flowthrough head. Carburetor on one side and exhaust on the other side. Can any one tell me what year and model it is ? Link to comment Share on other sites More sharing options...

Pfeil Posted August 6 Share Posted August 6 (edited) All Pontiac V-8's are crossflow and the INDY 4 cylinder which uses the Pontiac V-8-cylinder head. Edited August 6 by Pfeil (see edit history) 2 Link to comment Share on other sites More sharing options...

Pfeil Posted August 7 Share Posted August 7 (edited) 28 minutes ago, dodge28 said: Pfeil, I trust your judgement. Thank you. dodge28 Pontiac's first engine the split head six (a inline six with two cylinder heads) (1926-1932) and the Oakland/Pontiac V-8 (Pontiac only 1932) and Pontiac engineer Ben Anibal who designed the Pontiac Straight Eight 1933-1954 and the variation of the straight eight Pontiac's straight six (two of the eights cylinders lopped off) were not cross flow but were flathead design (the exception of flathead would be the 1932 Pontiac V-8 meaning that it's head design/block was multi angled and not completely flat but also not crossflowed. Pontiac's OHC six of 1966-1969 also was not a crossflow head. The only real Pontiac 4 cylinder besides the Indy 4 would be the Iron Duke 1977-1993 and it is a crossflow head design. FYI, exhaust and intake that enter and exit the same direction is called a reverse flow head or in the flathead's case a reverse flow block.
