I have edelbroc hedders currently on my tpi and I am going to be doing the lt1 swap some time in the near future as money permits. Will they fit or do I have to buy the hedemin ones.

Headers made for an 4th gen will not fit a thirdgen. This has been discussed many times on these boards.

You will need to use headers built for a 3rd gen car, even when a LTx engine has been dropped in.

Please read, think, then post.

Yes your TPI (hey thats where we know his headers are thirdgen) headers will fit, the edelbrocks arent ideal for the port alignment as i've checked and they dont fully surround the port, however they do not leak, and are ideal when fabricating a/c lines, a/c lines with SLP headers or most of the others would be a pita IMO without a tubular K.

Ok thanks a lot. I don't think I will be running ac but good to know.
