Just wondering if anybody can offer some insight as to what needs to be done to convert a 93 over to LT4? I did a search and only found info on having to change the fuel rails to 94. What else needs to be done?

I am thinking about doing this over the winter and would like some help to get a head start!

 

Can u say get your heads (or a spare set) ported by phil at advanced induction or lloyd elliot (nightrain66) and you'll probable have a good 30 rwhp over stock LT4 heads!!!!!

 

As far as I know, the fuel rails is it. Everything else is a standard part. Provided the LT4 kit doesn't come with the LT4 ED timing chain. If that was the case, then you'd have to swap out your timing cover for a 95+, opti for a vented opti, cam dowel pin for a longer one, and make one minor mod to a vac line going into the intake. Oh, and the opti harness will plug right in, you just have to cut down the key on the plug.
