5.3 swap into '80 Firebird exhaust question I have been searching the forums to get info but have not been able to find out if any of the stock ls1 exhaust manifolds will work for my swap. I've got a 1980 Firebird T/A and a 5.3 truck motor in it. I need to find out if the ls1 camaro or any of the lsx corvette stock exhaust manifolds will fit. I know that Sanderson makes a header for my swap but stock manifolds are way cheaper and cost is a big factor right now. Any ideas?

I'm in the same boat with my 76, I have a 5.3 engine and was wondering if the stock LS1 manifolds would work?
I have also seen some full length headers for sale on eBay that look like they may be a direct swap (location wise) for the headers currently on my older 350. Which means no extra mods- possibly?

Have you looked into the stock truck manifolds? I just put a 5.3 in my '70 Camaro using the stock manifolds and 1" set back plates. They fit with a little bit of grinding around the collector flange and shortening of one of the driver side studs.
