I have a 70 bee 383 4 bbl, auto, etc and I need to know if any of these intakes would be correct enough to use for my car??
My original engine is dated 8-26-69,
the stamped pad by the dist has - F 383, 3 11, hp
on it.

One question is would a 69 intake be correct #2806301 since the casting date on the block is 8-26-69?? or do I need a 70 intake # 2951666 ???

Question #2 my #2951666-1 what does the -1 mean???

and the last question, I have 2 intakes with #2951666 on them and one has a date code of 5.3.9 I assume this one is May 3rd 1969 and the other is 5.02 what are these dates as I can't find the info in my galen white book.

Any Help on these questions would Help me out Greatly. If neither intake is close for my car let me know Please.
Thanks David
