I have a 92 camaro with a 305 tbi motor and I want to switch to a 350. What motor years do I need to look for? Can I use the GM 350/330 motor or will it not work cause of the vortec heads. The reason I am asking is because I have heard the the bolt's angles into the heads differ from certain years. Anyone I need some help. Also do I need to change to 350 injectors?

 

You can use the GM 330 with great success. The main thing is that you will need a new chip, 350 knock sensor, larger injectors and a few other goodies. It is pretty simple when you break it down. As for bolt hole angles; using vortec heads will require you to use a vortec intake. Also they do not have internal EGR passage and you either have to have an external EGR or program it out of the chip. Try a search and you will find enouhg stuff to read for days. Good luck
