Re: wtb exhaust manifolds

I've got a set laying in the garage off an 88 c1500 350. I checked them out yesterday and didn't see any cracks. Let me know and I'll send pics.

Re: wtb exhaust manifolds

I still have a set that are like new on the shelf. I've used Borla headers on my truck for the last twenty-five years. I can take pics of mine later tomorrow if you're interested. I sold the Y-pipe a couple of months ago.

Re: wtb exhaust manifolds

I think these are what you need. These are 305 originals. They came off my truck in '93 and have been on the shelf since. I now have Borlas on my 350 and so no need for them. One thing that may be an issue. Cast iron "shrinks" and you might need a spreader between the mounting points to start the bolts. They actually have a tool for this and you should be able to verify this with Chevy Tech. I might also have a good set of bolts for these. I may be able to dig them up.

Re: wtb exhaust manifolds

I also have a set of manifolds that came off my '73 307 squarebody that have AIR tubes. I have another set of manifolds that came off a '90 Impala/ Cadillac that have AIR tubes but are much different design-wise. Those manifolds have more of an upswept design.
