What would the proper intake manifold be for a L88 intake manifold and I know there are certain dates that would be acetable what are the ranges?

Larry,

1967:
#3886093

1968-69:
#3933198

Can't help you on the date ranges.

NOTE: Both of these are Open Plenum......meaning "boggy" at low rpm's. You'll want an appropriate cam and gearing to make these streetable.

Thanks For some reason I thought it was an 069 manifold

I just aquired an o69 manifold and was told it was meant for the l88 for because of the date codes.

This one still has the divided plenum. Thanks again.

The 069 manifold is listed by NCRS as used on '66 L-72, '67 L-88, and "possible" use on the '68 L-88.
