TBI swap question

[Ackattack]

I going to be swapping a TBI 350 into my 69 real soon here. I think I have a handle on most things.

My one undecided thought was about the exhaust system.

I can use the original 69 exhaust manifolds with the fairly new hooker dual exhaust system I have on the truck now. Its a little louder than I want, and I don't think its sealing real well at the manifolds. I'd also have to add a O2 bung, but that's not a real big deal.

The other option is to use the exhaust manifolds and exhaust system off of the 91 donor truck. The exhaust system appears to be relatively new and is much quieter. The cat has already been removed by the previous owner (probably when it was replaced). I would have to modify it a little since the donor truck is a LWB, and my 69 is a SWB, then I'd have to fit it up and around the trailing arms too. My one big concern with this option is the clutch linkage. My 69 has a 4speed, and the clutch linkage attaches to the engine block very close to where the TBI exhaust manifold collector is. Is this going to be an interference? Will it even work? Does the "newer" engine even have the mounting holes for the clutch linkage? I haven't checked, but I assume it does since it's still a genI sbc (but of course its a later roller engine...so maybe not).

I also like the design of the TBI manifolds since the since the spark plug wires don't have to run around and under the manifolds, but rather are on top of the manifolds.
