    Hi, I will be swapping a 5.3L Vortec into my 79 z28. After looking around I couldn't find anyone selling headers that specified they fit F bodies. Does anyone know where you could get any?

    They're a little pricey (most of them are) but Ultimate Headers has built the nicest, most tightly built pieces (Longtubes and midlengths) I've seen on the LS swapped 2nd gens. I've used several sets at our shop and they're fantastic.

    Speed Engineering. I paid under $300.00 for stainless.

    I used Hedman mid length on my swap, they were pretty cost effective a few years ago, mine are ceramic coated.

    I went with Speed Engineering 1 3/4". They fit easily from the top. Has o2 bungs welded too. Welds have good penetration and no sugar.

    Manifolds work pretty good on LS engines. I scored a pair of 6.2 ZL1 exhaust manifolds that are stainless steel for $50. Looks like they would fit right in if I ever make the swap some day.

    yeah, they are pretty good for a stock manifold. For $300 though i would try the headers. Seems some of these manifolds are $$$

    That's what I thought, if those manifolds can feed a 500hp engine, they would work ok on a 5.3 N/A engine some day.
