TPI Base from a vette? Can I still use it?
So I bought part number...excuse me CASTING number 10088015 of CL on the cheap. Pro ported, ready to roll. The part number comes up via search, but there's not 100% clear answers as to when and from what car this manifold came from. The guy I bought it from is a vette guy, but he bought it used also, and never used it himself.
Here's what I know. It's got the Cold start hole. I can just run block off, right? They seem to be pretty cheap off ebay.
I have the EGR programmed out, so regardless, that shouldn't matter, right?
From what I've been reading, coil mount may differ
slightly, but that's an easy fix.
The bolt holes are angled (pre 87?), and they won't fit my 89 L98 heads, but I have some RHS heads on the way, that DO have the earlier style holes.
Is there anything else I need to add or delete? I can't think of anything, but for all the times I've had my manifold off, I've always used the same, stock base, so I've never had to deal with last minute "oh craps!"

...so as I'm staring at this manifold, I'm learning. LOL. ..it does NOT have the rear EGR hole/fitting, so it HAS to be an F Body manifold, right?
With regard to the 9th injector cold start- My runners, tune, and fuel rail are all from my 89, so NO 9th injector. No holes to block. Are there any differences in the manifolds themselves? ...and anything I need to do?

The TPI Swapper's Guide would come in handy here. Just going from memory here, but the only difference Corvette to F-body TPI is the EGR port at the back, and the bolt angles. No EGR at the back, should mean it's a F-body part. Within the F-bodies, the only difference early to late is the bolt angles. So if it'll bolt to your heads, you're good to go. As you already figured out, the runners will cover up the CSI port, so you don't need to worry about a delete plug.
