Can i use this engine?
Alright ui once posted about being able to use the TPi plenum on the GM 350 HO, but now i'm wondering about being able to use the GM Goodwrench 350 in it since it doen't have vortec heads.
Also would this engine be much of an upgrade from the 350 that came in later models?

Yes you can use TPI intake on that motor, and no it's not an upgrade. Most likely a downgrade.
