'91 chevy exhaust manifold casting numbers
Hi guys,
I am trying to find the correct L and R side exhaust manifolds for my '91 305TPI Z28. Can anyone share the casting numbers for both the L and R side. I thought I had them recorded but can't seem to find them.
TIA

Re: '91 chevy exhaust manifold casting numbers
Thanks James, I actully found them
However, what is the #14094084 casting used for. I searched on here and some threads read that this casting was used for the LG4 and L69 cars, but after looking into my GM parts and illustration catalog, Lg4's and L69 came with #14043373 and (rh )#14031361
I ask as I came acorss a #084 casting from a 1991 Z28 with the L98, yet the L98 (according to this GM book manual) came with #063 and #064) for this year.
Is the #084 a corvette casting?
Also what do the prefix and suffix 05200 and 2130M and 2130N represent? are these Jullian dates? (ie; 05200=52day of 1990, and 2130 = 213 day of 1990)?
05200 preceeded the #084 casting (right side) on the left #063 manifold. 2130M casting # and tbe 2130N
Can any one shed some light on this for me please?
