I’m currently ordering parts for a head and cam swap for a ‘00 Z28. This is a super “mild” build with a tight budget. The heads will be PRC 220’s and it’ll have a mild summit cam. The specs are 218/227 .600/.600 112+2.
It has the stock LS1 manifold and unfortunately it looks like I’m going to have to keep it. I’ve been shopping LS6 manifolds but most of them have broken pieces and people still want $400+ for them. $400 is too much for a manifold with pieces broken off. The Dorman LS6 is obsolete so that’s a no go. The only new option is the Fast brand and it‘s close to $1,300. I don’t believe thar the OEM TB will work with it so I‘d have to buy a larger one. $2k or so for a new intake is insane and it’s just not in the budget.
This isn’t really a power making focused build. It’s more of a getting it back up and running type build. I’m not even replacing the factory exhaust. I would upgrade the intake manifold if it was cheap enough but that doesn‘t look to be the case. Hopefully my mild little combo makes at least 330 at the wheels. We’ll see I guess.
