i think this is the engine L98 engine.

and this is the LO5

Both of those have crappy heads.

These are the Vortec headed engines and with a cam change should run very well. They may even offer a better cam as an upgrade.

we live in Cali, vortec heads really arnt an option for us if we want to pass emissions

 

if you can sneak the no egr past them then it should pass with a stock unmodified vortec headed motor. If im not mistaken, the exasust recirculation is done through the cam timing.

 

or... you could jsut plumb a line to the manifold form one of the exaust maniflds/header primaries. Gm makes an intake just for this application witht eh roundabout egr built in.

 

yeah i could do that, but that engine is still more expensive. thats y i was goin to get the lo5 and add heads later. i really just wanted to know if these engines are good.

 

heads are very much an option in cali. there is a wide variety of heads that have passed CARB certification, including all of those tha come on factory vehicles. tha tmeans the vortec heads are in as long as you get a egr kit for it.

later

how much is the EGR kit?, because if i can get the cheap vortec heads, i might as well start with a shortblock and just build it up.

 

should just be able to get the manifold from GMPP along w/ an egr valve. Requires some welding for the exaust feed but thats about it. All the rest should be straight forward.
