was it used on. I bought a really nice extruded honed base, but I think it fits L98 vette. Will it work on my 91 GTA L98??? Help is needed

I have two bases:

Stock base off of my 89 GTA has a 10088016 number

A base I took off of a junkyard car with no VIN available reads 14081005. It appears to be an LPE type of ported base by the looks. I got LPE runners and a professionally looking ported plenum also...reason I think the base was done by someone. Either way...it is a pre-89 base with cold start injector provisions, etc. Specific Model year unknown.

If it fits the L98 vette with the aluminum heads, the 4 center bolts won't line up right on your iron-headed 91 l98 (with the different angled center bolts)...

i have a base from an 88gta - stock - can send photos
if needed - part#14081006 - ported by local shop

my aftermarket base for 89gta - part # 10108468

four inner holes are angled. I hear that the EGR are different with the vette. I'll take a photo of it tomorrow, maybe that will help.

will this help?if you look at the back of the passenger there is fittting that is screwed into the base and right next to it there boss that is for a crossover tube going to the exhaust manifold.there also so stud bosses for the fuel rail covers.

I just check it, no it does not have the studs for the fuel rail, nor the fitting on the back. Is that manifold off of a vette? Please check back, I'll have a pix up tomorrow night (pacific time)
