Some who have read my previous threads know I'm changing to factory HP logs as part of the 440 rebuild. The current left side log is casting #3830800 and appears to have the distinctive up sweep to the top of the valve cover. The 2nd # in the casting is blurred and could be a 6 or 3. Can anyone confirm if it is a HP manifold? BTW the right side is low and straight across so I'm sure it is a LoPo log. Thanks. <span class='smallblacktext'>[ Edited ]</span>

This picture also shows the 2806900 & 2863409 combo (top and bottom) but it also includes the 2951216 (center) which is basically identical to the 2863409 except it has fins and has the mounting holes for a stove.
My dual snorkel air-cleaner has the plumbing to use a stove, so I'm going to use the 2806900 & 2951216 combo.
That is the HP manifold off a 75-76 engine (#3830800). It was also used on some trucks in the 70's. It will work okay in your car, but you cant hook up a TTI system to it, you will have to have a shop make your pipes.
Well blow me down! I had no idea that HP manifolds for 1975 even existed. So here is a pic of the right side manifold #4081488. I couldn't be lucky twice could I?
