    What are you putting it into? That helps. I put these in just about everything and have a spreadsheet with a list of PN#'s and vendors.

    Sorry, 64 Elcamino. Seen it on car craft website, and heard of it on other sites.

    Are you keeping the fuel injection or switching to a carb? You will need motor mounts. Do you want headers or are you keeping the stock manifolds?

    Going carb will save on $$ but if you go FI you need ECU and a harness. Stock manifolds may work but I run block huggers. Also stock auto or manual? Throw up some details on the build and we can point you in the right direction

    Keeping the EFI, I think I will have to use a F-body manifold on the drivers side.
    I hope everyhting else will be easy. The ECU reprogram will be outsourced to keep me from butchering it.

    fbody manifold is a good fit with exception of O2 sensor. It is located on front side of manifold and points it right in to crossmember. It can be plugged and then add O2 bung to pipe. Left manifold has enough meat it can be modified to accept standard 3 bolt header collector if wanted.
